More About Crazytunia® ‘Black Mamba’
The Black Mamba Petunia is part of the innovative Crazytunia® series bred by Westhoff, a breeder known for bold colors and unique patterns in annuals. Unlike lighter petunia cultivars, Black Mamba produces deep, velvety blooms that appear nearly black, thanks to very high concentrations of anthocyanins.
Compared to similar varieties like Black Magic Petunia, Black Mamba holds its dark coloration more consistently, with less purple undertone showing in bright sun. This makes it one of the truest “black” petunias available today, and a standout choice for gardeners looking to add drama to their plantings.
Why We Like It (Our Trials)
At Garden Delivery, we’ve tested Black Mamba side by side with other dark-flowered petunias in both containers and open beds. What stood out most was its uniform growth and fade resistance in our South Carolina trial garden. While some “black” petunias lose intensity under summer heat, Black Mamba maintained rich color well into July.
We also love its flexibility: it works equally well in mass plantings, where the velvety blooms create a carpet of dark color, or in small mixed containers, where it adds striking contrast against white calibrachoa, yellow petunias, or silver foliage plants. Customers who see it in person often describe it as “the most unique flower they’ve ever grown.”
Black Mamba vs. Other Black Petunias
While the Black Mamba Petunia is one of the deepest, most velvety blooms you’ll find, it’s part of a wider family of black petunias that each bring something unique to the garden. Compared to Black Magic Petunia, which has a trailing habit perfect for hanging baskets, Black Mamba stays more compact and uniform, making it ideal for beds and borders. Additionally, the historic Black Velvet Petunia was the first variety introduced to the market, but it tends to be less available today.
