Are Black Petunias Rare

Black petunias are rare flowers that are difficult to reproduce. Many varieties of black petunias are trademarked or patented. Black petunia plants can’t be grown from seed.

Are black petunias natural?

“The black colour did not exist in petunias before, so it has to come from the right recombination of a novel color mutant and multiple regular color genetic backgrounds,” she said.

How do black petunias grow?

Like other petunias, plant “Black Velvet” petunias in an area of the garden that receives full sun and has rich, well-draining soil. Petunias need regular water and will quickly fade in dry soil. Feed your petunias a balanced fertilizer once a month or provide a slow-release fertilizer when you transplant them outside.
