Vincas are valued for the summer and fall color they provide everywhere, but are especially welcome in desert regions of the West. They thrive in almost any soil and prefer some shade, although they will grow in sunny sites provided they are well watered. How to Grow: Start vinca seeds indoors three or four months before the last frost is due, or buy started plants. Set the seedlings in the garden 8 to 10 inches apart after all danger of frost has passed. This plant is a perennial in Zones 9-10. New plants are usually started from seeds early each spring, however, because old plants become unkempt in appearance. They flower most freely in hot weather. |
