They should bloom in the Spring if you plant them by or before the Fall season. They do well in shade or sun, but do not like to be overcrowded. They should be planted 1 or 2 inches deep in rich soil or compost, and 3-5 inches apart. They will multiply and when they become overcrowded in a year or two, it is advantageous to dig them up and spread them out again. They will grow about 15 inches tall.
Such a lovely color! Requires no care once planted.
