Summer Buttercups or Shamrocks are a wildflower from Chile and Argentina. Pink flowers appear over silvery foliage in late spring to early summer. Excellent groundcover. (Oxalis adenophylla)
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).
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 late spring to early summer. So this one offers you lovely pink flowers and attractive foliage for your 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.
