Comments: This perennial is noted for its bright yellow flowers that appear in spring. Grow it in the cooler regions of the country. Cannot tolerate the hot, humid South. Diseases may be a problem in summer, especially in the South. Try it as a cool-season annual where temperatures are high in the summer.
