Petunia, Supercascade Blue

Tender perennial that is winter hardy to USDA Zones 10-11. In other zones it is grown as an annual. Performs well in average, medium moisture, well-drained soils in full sun to light shade. Tolerates poor soils as long as drainage is good. Although many petunias may be grown from seed sown indoors 10-12 weeks before last frost date, many gardeners search local nurseries for interesting cultivars in inexpensive cell/six packs and only resort to seed in situations where a specific cultivar is sought that is only available from seed. Purchased plants often benefit from pinching at the time of planting. Prompt deadheading of spent flowers promotes more rapid formation of new buds. Cut back plants that become leggy.
