Oca, Mixed Colors (Oxalis tuberosa) potted plant, organic

(3 customer reviews)

$8.50$22.50

Family: Oxalis (Oxalidaceae)

Hardy to Zones 6 to 12, otherwise grown as an annual, 180 days to tubers

Andean foodcrop rivalling potatoes in taste and exceeding them substantially in handsomeness.  Highly nutritious tuber with brilliant colors that make a welcome change from the potato.  Loaded with carbohydrate, calcium, iron and an excellent balance of amino acids.  Plant prefers full sun to part shade, moist soils, and is best hilled up as it grows, to promote formation of the tubers.  Requires 6 months from time of planting to time of harvest.  After aerial portions reach full size it will take the plants another 3 months to mature their tubers. Cool but frost-free conditions are favored.  Potted plants consist of the varicolored (mostly red or golden) tuber(s) in the pot and may be sold on the basis of a live tuber in a pot or on the basis of a plant, depending on growth cycle.

Potted Plant, Certified Organically Grown

    The plants that I purchased from you in spring have started producing tubers in my winter greenhouse in northern MN. What would you recommend that I do with the tubers that I plan to sprout for the 2020 garden?

      Under the circumstances I’d recommend planting to gallons now ank keeping in the cold greenhouse. They’ll sprout back up as the days lengthen and the soil warms. r

      Hi Richo
      Mike again. Any Food crops that can grow in a space like that?

    They do like it cool

    Healthy seedlings arrived last spring, but I made the mistake of planting them in the greenhouse (reasonable for zone 6-12 plants?) and watched them struggle all summer until late summer/early fall when they took off and started growing like crazy in the cooler conditions. They have continued to grow in the “winter greenhouse” (ave night temp 40C) and started producing tubers in late December. I plan to plant them in tubs outside in 2020, hoping they enjoy the cooler zone 3 summer temps, and will bring them in the greenhouse before frost.

  3. Question

    Merry

    Hi!
    If I order now – how do I store till spring? (Don’t want to kill them)
    Conversely, when do they ship if ordered for spring?
    I am in the northeast zone 6 – 6a
    Do deer eat them?

      Are the tubers high in oxalic acid/oxylates? Perhaps only the aerial portions are?

      The tubers taste mellow, not smacky and gritty like the way high-oxalic acid plants react to the palate. I don’t have the science on it, it is a reasonable food for most people taken on an occasional basis. r

      Hi Richo
      Live south of Seattle, have one area left in the yard with lots of trees and near no direct sunlight, but is open. Would Oca grow without direct sunlight? If not what shade vegetable could i put there?

      Oca does like shade and a cool aspect, also mounding of rich soil around the roots. Another option might be Sweet Cicely. r
