The U.S. Department of Agriculture has created a map of North America that divides the continent into growing zones, numbered from 1 to 11, with Zone 1 being the coldest zone located in Alaska and northern Canada and Zone 11 the warmest, located southern Florida and southern Central America.
Not surprisingly, given where it originated, candy cane sorrel needs a warm climate in order to thrive. It does well in USDA Hardiness Zones 7, 8 and 9. Candycane sorrel is hardy when winter temperatures do not go below 0 to 30 degrees Fahrenheit. Hardiness zones 7 to 9 go from one coast to the next in a shallow concave curve. Roughly, these zones start in the Mid-Atlantic states on the East Coast, dip down into Oklahoma and Texas, and meander in a discontinuous band up through California and the Northwest states. Consult a USDA Hardiness Zone map to get a good idea if candycane sorrel would thrive where you live.
Candycane sorrel grows from bulbs that should be planted in the fall. This specimen requires full sun to partial shade. Planting the bulbs in groups results in a striking early spring to early summer display. The stems grow 6 inches to 12 inches tall. Once established, the plant spreads as the tubers or bulbs multiply, and can be divided.
Several bulb providers sell candycane sorrel, but it is not yet a common specimen in the U.S., at time of writing. In fact, it is not even listed in the USDA's Natural Resources Conservation Service's Plants Database. Therefore, little information is available.
