Trailing Petunia Seeds

Trilogy Purple's rich rosy purple, 2.5 in. trumpets bloom in abundance from late spring through frost, maintaining a tidy, domelike shape without getting bare in the center. Heat and rain resistant plants grow 12-16 in. tall, densely spreading to 3 ft. across when planted in beds and borders; growth is more compact when planted in containers and hanging baskets.
