Periwinkle / Trailing Myrtle
V. minor rooted cuttings should be spaced 4 to 6 inches apart; potted plants can be spaced 12 to 15 inches apart. Choose a site in partial shade, though the Vincas will tolerate deeper shade as well; average garden soil will do.
Keep plants well watered during periods of drought. A balanced fertilizer applied in the spring will encourage optimum growth.
