Jewels of the Earth
In addition to potatoes, there is a shocking rainbow diversity of brightly colored tubers cultivated in the Andes where they have been a staple of rural communities for millennia. Largely ignored by the rest of the world, these “jewels of the earth” deserve to be widely grown. An alarming loss of heirloom cultivars has been observed in recent decades as land is given over to modern crops, such as carrots, that are associated with affluent culture. This makes preservation through integrating these enchanting and delicious tubers into our gardens all the more timely. Studies have shown all of these crops to be nutritious and high in antioxidants. Cultivation of some of these is still experimental, so let us know how they grow for you. We have live plants available April/May to November, bare root tubers available December through March/April, USA only.
Inquire for additional cultivars. Tubers are available USA only.
During late December through April every 3 tubers ordered count as 1 plant for shipping costs, we begin replanting the tubers in late April, so check that month for bare tuber availability. Regular plant shipping costs apply the rest of the year.
Apiaceae. Perennial celery-like plant with edible leaves. Forms clusters of large cream colored roots that are edible raw or cooked, a delicious flavor somewhere between a potato and carrot. Ancient cultivar grown throughout the mid elevation Andes. Not as common as it once was as “civilized” plants such as carrots take its place. For over a hundred years it has been grown in Puerto Rico as “Apio”, though cultivation is declining there as well. We offer clones from PR genetics. Z8a if well mulched
Plant $25 (limit 2 per customer)
Canna edulis ‘Rojo’ “Achira”
Cannaceae. Ginger-like perennial monocot to 6′. Large attractive foliage, green, sometimes with bronze highlights. Bright red lily-like flowers. Edible rhizomes. A cultivar throughout the mid-Andes. One of the “lost” crops of the Incas. The rhizomes are extremely rich in a large molecule starch and have been eaten since antiquity. Young shoots and immature seeds are also edible raw or cooked. Tolerant of diverse conditions, prefers moist soil. Often planted as a wind break. Knick and soak seed. Z8b if mulched. The main strain we offer has bronze and purple streaked leaves, dark reddish-brown seed pods and deep red flowers. True from seed.

Mirabilis expansa ‘Blanca’ Cl. A “Mauka” “Miso” “Tazo”
Nyctaginaceae. Herbaceous perennial to 2–3′, simple leaves. This clone has slightly pubescent leaves and small white flowers. Branched subterranean stems/tubers, thick, succulent and edible. White fleshed in this genotype. This is the rarest, least understood of the Andean tubers, known to science since the 1960s. Only known from 3 disparate locations- north of La Paz, Bolivia, near Cajamarca, Peru and the highlands of Pichincha & Cotopaxi, Ecuador. This is most likely the result of the Incan policy of mitma; relocating entire ethnic groups throughout the Andes. Mauka’s tubers are protein rich and high in calcium, phosphorous and potassium. Much still needs to be discovered about the cultural needs of the plant but it seems somewhat tolerant of both wet and dry conditions. Should be cold hardy to at least Z8 and likely Z7 if well mulched.
Plant $25 (limit 4 per customer)
Mirabilis expansa ‘Blanca’ cl. B “Mauka” “Miso” “Tazo”
This clone has smooth, leathery leaves with grayish hues in full sun. White flowers. Cream-white edible roots. Came to us from the fine folks at Peace Seeds.

Plant 1-2 years old $26 or 2 for $46
Neowerdermannia vorwerkii “Achacana”
Cactaceae. Spherical cactus to about 4″ diameter with dark green triangular tubercles. Curved spines, lilac-pink flowers and reddish fruit. Distributed from the altiplano of Bolivia to northern Argentina, from 10,000–13,000’+. The whole cactus is considered a kind of potato, it is gathered by the tens of thousands each summer, skinned, cooked and eaten. It is said to be very tasty and is a significant source of vitamin K, calcium and zinc. The pulp is also a remedy for stomach ailments and made into a drink for kidney and liver disease. There is some concern that harvesting may endanger the plant, but it has yet to be clarified how wild populations are impacted. Well worth cultivating as an unusual food plant. Needs strong light and gritty soil. Z7a or below.
Seed packet $4 (limited)
Oxalidaceae. Round to cylindrical tubers 1–6″ long. With hundreds of known cultivars in an alluring spectrum of colors from yellows to oranges, pinks and reds. Sprawling succulent stems to about 1′ tall with trifoliate clover-like leaves, yellow flowers. One of the easier Andean tubers to grow and second only to the potato in popularity. Cultivated for thousands of years, the tubers have a variety of flavors from crisp and lemony fresh to buttery and sweet when cooked. Still unknown as a food outside of South America with the exception of Mexico where it has been grown for over 200 years and New Zealand where it has been farmed recently. Grow similar to potatoes, the larger tubers develop late in the season after Autumnal Equinox with cool weather and shortened daylength. Traditionally the tubers are exposed to sun and cold for several days after harvest to increase sweetness. Light exposure also enriches the vivid colors. Oca also make captivating ornamental plants. If well mulched the tubers are hardy below Z7a.
These 5 Oca varieties are $12.50 each for tuber starts or plants,
or $42 for 4 varieties

Pachyrhizus ahipa “Ajipa” “Villu” “Andean Jicama”
Fabaceae. Semi-erect stems 1–2′ high with pubescent trifoliate leaves. Violet to white flowers and 3–4″ bean pods. Swollen edible root, elongated to spherical, weighing up to 1 kilo. Another ancient domesticate, unknown in the wild. Cultivated in the Yungas, Ceja de Selva and warm interAndean valleys of Bolivia , Peru and northern Argentina, between 5–10,000′. Our seed is from Tarija, southern Bolivia. This is the Andean jicama, with sweet crunchy flesh similar to the Mexican jicama (Pachyrrhizus erosus) many people are familiar with. Hardier, faster growing and more adaptable than Mexican jicama, this is a species that should do well in many gardens. Pest free, nitrogen fixing and daylength neutral. The root is rich in quality starch, minerals and protein. The foliage, pods and seeds contain the pesticide rotenone, moderately toxic to humans. Some plants show low rotenone content in the oil rich seeds, it is conceivable that an edible seed strain could be developed free of the toxin. About 4-6 months to harvest from seed, pinching the flowers back is said to increase root size. Prefers well draining soil and warmth. Sprout like beans. Cultivation of the plant is nearly extinct in Peru and Argentina and has been waning in Bolivia, integrating it into our gardens is an essential strategy for the conservation of this valuable ancient root crop. Z10a?
5 seed $4
Asteraceae. Clusters of knobby propagative tubers and large yam-like storage tubers. Fuzzy annual leaves and stems to 4’+ topped with yellow daisy-like flowers. A multi-use plant traditionally grown throughout the Andes, it has been introduced to Central America and is popular in New Zealand. The large storage tubers have a delicious juicy sweet taste, somewhat like a cross between jicama and watermelon. In the Andes it is thought of more as a fruit than a vegetable. The young vegetative growth is cooked similar to celery. The tubers are rich in fructooligosaccharides and are considered a prebiotic; that is, they feed the healthy bacteria in the gut which improves overall health. The leaves are used as a tea for diabetes. A molasses like syrup made from the roots is becoming popular as a beneficial sweetener. Easy to grow, prefers sun and a rich soil. This cultivar has proven itself very productive of sweet tubers even in tropical conditions such as Hawaii. Hardy to Z7b or 8a if well mulched.
Propagative tubers or plant $9.50
Smallanthus sonchifolius ‘OE’
An Oregon Exotics intro. This may be ‘Pearl of Bolivia’ but we are not sure. Very highly productive fast growing tubers with brown skin and pearly white flesh with an excellent sweet flavor. Z7b/8a
Plant/ Tuber $12.50
Smallanthus sonchifolius ‘Morado’ “Purple Yacon”
This may be the variety originally introduced by Oregon Exotics as “Purple Puma”. Annual stems show some purple streaking. The orange-yellow flowers are a little larger than other varieties. The propagative tubers are a bright violet-purple, the fat juicy storage tubers have a purple to brown-purple skin and white flesh that sometimes infuses violet with light exposure. Surely rich in anthocyanins. Delicious sweet flavor. We now have a good stock on hand! Hardy to Z7b or 8a if well mulched.
Smallanthus sonchifolius ‘NZ’ “Yacon”
A clone selected for commercial cultivation in New Zealand. A bit more compact plant than other varieties. The tubers also tend to cluster closer together. The vegetative tubers are white to pale brown with pink banding. The edible storage tubers have a beige skin and white-yellow to very pale orange flesh. Hardy to Z7b or 8a if well mulched.
Plant $12.50 (Limited)
Inquire for other Yacon strains
Solanaceae. Low growing plant, often less than 6″ high. Rosettes of dark green, odd-pinnate leaves. Pale purple flowers and heart shaped fruit that often plant themselves below the soil. Small white tubers, 1/4–1.5″ diameter, round or oval and flattened. The tubers are borne on the end of long lavender colored stolons. This tetraploid wild potato is known from central Andean Peru down through Bolivia to northern Argentina, preferring the grasslands of the Puna. Occurs from about 9,000′ up to 15,000’+, often amongst Stipa ichu, Cajophora, Urtica and several cactus species. Even grows along the margins of permanent snowbanks. On of the ancestors of the Ruki potatoes cultivated in parts of Peru and Bolivia. Used in modern potato breeding to increase frost tolerance and resistance to disease and pests. The bite size tubers are perfect for soups. Good horticultural appeal and is of keen interest to experimental home gardeners. Sun to part shade. Resents extreme heat. Tubers hardy to Z5/6?
10 seed $4
Solanum sp. ‘La Paz’ “Bolivian Potato”
Leafy stems to 12″+. Purple flowers. Rounded to elongated grub-like tubers, magenta to dark purple skin, large cream colored eyes. White-yellow flesh. Collected by ethnobotanist Jim Bauml, La Paz, Bolivia. May be Solanum phureja or S. tuberosum ssp. andigena or one of the many ancient hybrids. Does not seem to have a real dormancy except when frost comes. Produces tubers throughout the year. Z6-7a?
Tropaeolaceae. Very fat deep yellow tubers, often rounded and rosette like. Annual climbing stems to 8′, rounded lobed leaves. Tubular orange flowers. A close relative to the garden nasturtium, a high yielding root crop throughout the Andes. Easy to grow, highly ornamental, pest resistant and repellent. The tubers are cooked like potatoes and can have a slight peppery flavor, this variety has a more mild and agreeable flavor than some mashua. Shown to reduce testosterone with regular consumption. Good producer. Leaves and flowers edible too. Another Oregon Exotics introduction that was thought lost. Z7a when mulched.
Cream colored grub-like tubers to 6″+ long with purple eyes, speckles and some red striations. Tubular bright-orange flowers. This is the plant that we had originally received as the horticultural selection ‘Ken Aslet’, and had been distributing under that name. However last year we obtained a tuber from a friend who said that is was the “real Ken Aslet”, and sure enough this new plant fits the description better. So we have renamed this very productive clone with an appropriate Quechua name. Similar to variety pilifera, but we believe this one to originate in Peru and the purple speckles and red striping are heavier with light exposure. One of the easier varieties to grow. Z7a when mulched.
Tubers or plant $9.50
Tropaeolum tuberosum ‘Q’illu-isañu’ “Mashua” “Añu”
Tropaeolum tuberosum ‘Chilean Red’ “Mashua” “Añu”
Vine with purple stems. Round to cylindrical tubers; pale yellow, orange and deep red. Early in the season they unearth yellow and peach colored, the longer they stay in the ground the darker the red coloring. Fast growing and very productive for us. Z7a if mulched
Elongated cylindrical tubers, yellow with heavy purple-red flecking and lines that often entirely cover the tuber. The vines also have dark purple stems. This description fits the true variety lineamaculata. Highly productive. Originally introduced by Oregon Exotics. Z7a when mulched.
Tropaeolum tuberosum v. pilifera “Mashua Blanco” “Añu”
Vine with rounded lobed leaves, orange flowers. 2″ to 6″+ white to cream colored edible tubers with purple eyes and with light exposure: fine purple speckles near the stem. According to Cardenas this white variety originates in Columbia. This is probably the easiest and most productive of the Mashua for us, though the tubers are not as showy as other varieties. Z7 if well mulched.
Tropaeolum tuberosum ssp. silvestre BK08524.14 “Mashua Silvestre” “Añu Silvestre”
Large vine with lobed leaves and attractive orange-red flowers. Wild form of this ancient Andean tuber crop. In the Fall it forms porcelain white, finger thick, edible tubers up to 12″ long. These become flecked reddish with light exposure. Mother plant growing on a rock wall edging a traditional garden of corn and kiwicha, above Lares, Cusco Dept., Peru, 11,300′. Leaves and flowers edible. The tubers are also used medicinally for skin infections. Beautiful and edible, wild Mashua will also prove useful for breeding with the cultivated forms. We offer tubers/plants from several seed grown parent plants. Grow like the cultivated Mashua. Z7 if well mulched.
Tropaeolum tuberosum ssp. silvestre BK10501.2 “Mashua Silvestre” “Añu Silvestre”
No Photo. Clambering vine with lobed, rounded leaves. Small orange-yellow-red flowers. Come Autumn it forms finger thick edible tubers to 12″ long, pure white with a little pinkish flecking, turning purple-red when exposed to light. Another seed collection of wild Mashua from a plant growing on shrubs on ancient Incan terracing, Killarumiyoq, near 12,000′, Cusco Dept., Peru. We offer tubers/plants from our seed grown mother plant. Z7 if well mulched.
Mashua Collection $70* includes 7 varietals (all except Q’illu-isanu ) a $85 value! * add just $8 shipping for bareroot tubers/plants
Ullucus tuberosus “Papa Lisa” “Ulluco” “Melloco”
Basellaceae. Hundreds of cultivars with 1–4″+ round to cylindrical tubers, a delighful array of bright colors. Edible spinach-like rounded leaves on short sprawling stems to 12″. One of the most delectable of all the Andean tuber crops, yet practically unknown in the U.S. Crisp and buttery in flavor. Shown to have antiviral properties. Contains triterpenoid saponins which may help with hypoglycemia. Like oca the tubers only develop late in the season. Tuber production is best in areas with a slow transition from Summer to Autumn. A little fussy, but so far they seem adaptable to northern California. Hardy below Z7a when well mulched. (inquire for additional cultivars)
The following 11 Ulluco varieties are $14.50 each for tuber starts or plants, or $60 for any 5 varieties
Ullucus tuberosus Bauml ‘Pica de Pulga’
Small rounded tubers to 2″, a delightful yellow with neon-pink stars. The name means “flea bitten”. Bauml selection, La Paz, Bolivia. (limited)
Ullucus tuberosus BK08607.1
1–2″ round “pica de pulga” type; yellow to orange with fluorescent red to pink spots. Chulumani, Yungas, Bolivia.
Ullucus tuberosus BK08607.2
1–2″ round, pure fluorescent red-pink tubers, delicious. Chulumani, Yungas, Bolivia.
Ullucus tuberosus BK09510.2
1–3″ round or elongated deep-orange tubers, like gold nuggets. Caraz, Ancash Dept., Peru.
Ullucus tuberosus BK10425.2
3–4″+ grub-like cylindrical yellow tubers with flourescent pink splotches. Traditionally cultivated near Patacancha, Cusco Dept., Peru.
Ullucus tuberosus BK10429.1
Pale to bright yellow round to cylindrical tubers with slender pale pink “eyes”. From G. Quispe, Chinchero, Cusco Dept., Peru.
Ullucus tuberosus BK10429.2
1–2″+ Pale to darker yellow lumpy oblong tubers, occasionally with a purplish blotch. From our friend Grimalda Quispe in Chinchero, Cusco Dept., Peru. In addition to eating she says the sliced tubers are used on bug bites, burns and swellings; including swollen lymph.
Ullucus tuberosus ‘Llanqha-puca’
Round tubers up to 2″ diameter, colored a deep, dark pink to red. La Paz, Bolivia.
Ullucus tuberosus ‘Illimani’
New. Rounded chunky tubers, bright yellow with occasional pink speckles. Cultivated on the slopes of Apu Illimani, La Paz, Bolivia. (limited)
Ullucus tuberosus ‘Bogota’
Elongated cylindrical deep pink tubers, like a fluorescent grub! Paloquemo Market, Bogota, Columbia.
Ullucus tuberosus ‘Chugua Roja’
Rounded rose-pink tubers. From Boyaca, Columbia.
Ullucus tuberosus ‘Lisa Amarillo’
Cylindrical bright yellow tubers from Cusco, Dept., Peru.
Ullucus tuberosus ssp. aborigineus “Ulluco Silvestre” “Wild Ulluco”
Trailing vine to 2–10’+ with heart-like edible leaves. 1/2–2″+ round or oblong tubers, varying from white to pink or lavender, turning almost purple-brown with light exposure. This is considered the wild form or ancestor of the cultivated ulluco. In our experience the tubers are just as edible as the cultivars and only slightly smaller. The leaves are delicious like spinach. Cultivated ulluco very rarely sets seed and this wild subspecies, which seeds more readily, could be used in breeding programs. It has been speculated that it was used in breeding new varietals by the Incas. Grow as you would other ulluco, but give more room for the vine. A good source for edible greens, the leaves are larger and more abundant than the cultivars. In our initial trials one pea sized tuber produced nearly 4 oz of tubers in a season. First introductions, unknown in cultivation. Z6 to 7
These 4 Wild Ulluco varieties are $13.50 each for tuber starts or plants, or $48 for 4 plants
Ullucus tuberosus ssp. aborigineus BK10426.5
Trailing vine to 24″+. Chunky lavender tubers to 2″+. Growing in Incan stone terrace walls with Peperomia rotundata. Halfway from Pumamarca to Munaypata, Cusco, Peru, 10,500′. This accession was made at one of the most heavily terraced mountainsides we’ve seen in all of the Andes. With over a thousand stone terraces it must have been a site of intensive agriculture.
Ullucus tuberosus ssp. aborigineus BK10426.6
Sprawling vine to 36″+. Odd shaped lavender-pink tubers to 2.5″. Growing amongst dilapidated Incan walls above Munaypata, Cusco Dept., Peru, 10,400′.
Ullucus tuberosus spp. aborgineus BK10427.5
Vine to 24″+, small pale pink tubers. Growing amongst boulders with Bomarea and Fuchsia apetala, above Patacancha village, Cusco Dept., Peru, 13,000′. Should be extra hardy.
Long dangling vines to 20’+ hanging on rocky cliffs next to waterfall, Inkallajta, Cochabamba, Bolivia, 10,000′. Pale to dark lavender tubers, round to oblong. These were the longest vines we’ve seen from the wild ulluco. Reported to be utilized in the region for gastrointestinal problems. This varietal may be more adaptable to warmer conditions than the others.
Complete Ulluco Collection $130* includes all 12 varietals (8 cultivars, 4 wild) we offer,
a $170 value! * add $13 shipping
Cultivation of Andean Tubers
General information for all: Plant tubers 2-6″ deep. They all are tolerant of a wide range of soils, but definitely grow best in a relatively rich, well draining soil. We use 25% pumice stone, 10-15% sand and the rest compost/garden loam. Gophers are particularly fond of all these plants, so we grow these in half wine barrels or raised beds with wire mesh on the bottom. In the colder climates, several inches of mulch will help assure tuber survival through heavy frosts. In climates below Z7, the tubers can be overwintered in moist coir or sand in a cool place, then replanted at the start of the growing season. Though tolerant of a little shade, all do best in a sunny location.
Canna: This is the least cold hardy them all, but can still tolerate Z8a or even 7b if very well mulched. Achira is also much more tolerant of extreme heat and wet or even soggy soil. The rhizomes are best harvested after the tops of the plant have died back from frost or a dry period. Make sure to replant a few of the nippled growing tips of the rhizome for continued harvests.
Oxalis: One of the most adaptable of the tuber crops. Some varietals seem more tolerant of high Summer temperatures than others. Since tuber production does not begin until after the Autumn Equinox when the daylength shortens and the days cool, the largest tubers are produced if you can keep the tops protected from hard frost (they are tolerant of light frost) and growing as long as possible (this goes for Tropaeolum and Ullucus as well.) If you do not live in an area with a long mild Autumn season, you have a couple options. One method is to stake some hoops over the plants with frost protectant fabric or even greenhouse plastic. One other trick is to cover them with shade cloth a few weeks prior to the Equinox to simulate shortened daylight and encourage early tuber forming. We are finding that well before the shortened daylength it is good to mound extra soil around the stems, as you would potatoes, to encourage additional tuber formation. The tubers can be harvested after the tops of the plant finally die back. In general, the more cold the tubers are exposed to the sweeter they become, so a late harvest is usually preferable. Traditionally the tubers are exposed to sun and cold for several days after harvest to break down any oxalic acids and increase sweetness. Exposure to light also enriches the vivid colors. Tubers can be left in the ground for next years plants, or stored tubers can be replanted in the Spring. Like potatoes, the tubers can be cut into pieces for propagation.
Smallanthus: One of the most adaptable to warmer climates, some clones have even proven themselves in the tropics. It’s important to differentiate what’s the propagative tuber and what’s the edible storage tubers. The propagative tuber (what you’d receive from us) is knobby, eventually clustering, often cream colored, brown, or even purple when exposed to light. It looks very much like its close relative the sunchoke (jerusalem artichoke). The edible storage tubers grow off the other tubers and are long (to 10″+), smooth, usually brown or white, and shaped like yams. New plants cannot be propagated from these. The propagative tuber clusters can eventually grow quite large (we’ve had them basketball size), and these can be broken up to further propagate the plant. Some clones are very sweet harvested any time of the year, while others are a bit sour until exposed to repeated frosts.
Tropaeolum: Best given something for the vines to climb on. In general, mashua dislikes heat, preferring a long cool and moist season. Most varieties are daylength sensitive for tuber production, after the Autumn Equinox they should be cultured similar to Oxalis (see entry above). The ‘Ken Aslet’ variety has been grown as an ornamental for some time and is not particularly sensitive to daylength for tuber forming, though greatest tuber formation is still Autumn. Vegetative growth is tolerant of mild frost, but dies back to the tubers after heavy frost. Flowers are formed late in the season, but can be encouraged earlier by holding back water.
Ullucus: A little more challenging than the others, but well worth any effort. Most varieties resent too much heat. They also seem to be sensitive to being transplanted into overly rich “hot” soil, often rotting. The best treatment is gradually applying small amounts of compost/fertilizer as a mulch throughout the growing season. Even more than oca, they only produce their lovely tubers well after the Autumn Equinox, sending out small stolons that slowly grow into tubers. See the Oxalis entry above for additional growing info. Unlike oca, the bright tuber colors quickly turn green when exposed to light, though unlike true potatoes, they are still safe to eat.

This means that all plants and seeds are supplied solely under the following conditions: We expressly prohibit the use of any seeds or plants supplied by us, or their progeny, in any form of genetic engineering, breeding, or research which will result in any form of life patent, variety protection, trademarks, breeder’s rights or any form of intellectual property applied to living things which would compromise the Public Domain status of the seeds, plants, their progeny and any genetic material therein. We expressly prohibit the transfer to any third party of any seeds, plants, their progeny or any portion of their genetic material without these prohibitions in place. Commercial propagation is encouraged, but in the unlikely event that large-scale commercial distribution is achieved, benefit-sharing along the path towards the source, in accordance with the spirit of the International Convention on Biological Diversity, will be undertaken. Thank you for your understanding and support!
