'Crazytunia Knight Rider' flowers are a unique combination of yellow petals edged in a deep purple, giving them a star-like appearance. This variety forms dense mounds of foliage about 12" tall and wide, perfect as fillers for container planters or hanging baskets, as well as in mass plantings or along borders in a sunny garden. As with most petunias, 'Knight Rider' blooms best in sunny conditions and maintains its good looks right up to fall if watered and fertilized regularly.
