Plant Information

This little floral treasure is from high in the mountains of South America, but is perfectly happy in most of North America. Planted in fall, these little irregularly-shaped bulbs bloom in mid-summer. So this one offers you lovely pink flowers and attractive foliage for your summer garden, year after year, in spreading clumps.

Of course, there are several wild Oxalis species native to North America, but most of ours do not have flowers as showy as this Latin American beauty.

      These flowers are a terrific ground cover. The foliage is interesting and the flower very pretty. Unfortunately the deer in my area could not leave them alone.

        I have spaced these little beauties along the edge of my bed of azaleas and rhodies. Their ruffled light green leaves are coming up now that spring is finally here. I am ready to order one more bag to complete the border.

          planted in the fall, so much fun to see things pop up where you forgot (no i do not make records of where things are!)
          that you planted anything. Everyday something new is blooming.
          Beautiful pink blossoms.

          Q & A

          Plant With These:

          USDA Hardiness Planting Zones

          To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low temperatures; the lower the zone number the colder the winter.

          • If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will survive the winter temperatures in your area.
          • If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack of freezing winter temperatures do not provide a time for winter dormancy (rest).
