A break-through in breeding, Lobularia hybrid 'Snow Princess' is extremely vigorous and stays covered in loads of small, white flowers creating snowballs of blooms. Because it is sterile it doesn't set seed, so it continues to bloom non-stop. Snow Princess is so different from Allysum that the breeders don't want it referred to by it's common name! Adds a playful and whimsical touch to your combinations and hanging baskets. Sun to partial shade.
