Visitors to the nursery love the name as much as the flower. 'Crazytunia Black Mamba' is indeed a matte black petunia, growing up to 10" tall and spreading 18" - 24" wide. Paired with pastel or cream colors, it makes an elegant, sophisticated container planter or basket. 'Black Mamba' with intense warm or cool colors creates a whole different feel - dramatic, fun, even mystical. No need to deadhead this petunia; just keep it well watered and fertilized throughout the growing season, and you'll be able to enjoy its good looks right up until freeze.
