Is nemesia cold hardy? Sadly, for northern gardeners, the answer is no, as this native of South Africa, which grows in USDA plant hardiness zones 9 and 10, definitely isn’t cold tolerant. Unless you have a greenhouse, the only way to grow nemesia (Nemesia) in winter is to live in a warm, southern climate.
The good news is, if your climate is chilly during the winter, you can enjoy this lovely plant during the warm weather months. Nemesia winter care isn’t necessary or realistic because there is no protection that can see this tender plant through a freezing winter. Read on to learn more about nemesia and cold tolerance.
About Nemesia in Winter
Does nemesia bloom in winter? Nemesia is generally grown as an annual. In the South, nemesia is planted in fall and will bloom throughout the winter and well into spring as long as temperatures aren’t too hot. Nemesia is a summer annual in cool northern climates, where it will bloom from late spring to the first frost.
Temperatures of 70 degrees F. (21 C.) during the day are ideal, with cooler temperatures during the night. However, growth slows when temperatures drop to 50 degrees F. (10 C.).
Newer hybrids are an exception, however. Look for Nemesia capensis, N. foetens, N. caerulea, N. pallida, and N. fruticans, which are more frost tolerant and can withstand temperatures as low as 32 degrees F. (0 C.). The newer nemesia hybrid plants also can tolerate a little more heat and will bloom longer in southern climates.
