Harris Seeds Petunia Trilogy Seed
Best vibrant annual for gardeners creating lush, early-blooming container displays.
These petunias take the guesswork out of spring displays by blooming early regardless of daylight hours. Their dense, dome-shaped habit makes them a reliable workhorse for hanging baskets, sacrificing a wild, trailing look for consistent, high-impact color that moves quickly off the shelf.
