If you’re looking to add a touch of drama to your garden, consider growing black flowers. These nearly black plants can give your outdoor space a unique and edgy vibe, perfect for gothic-themed gardens or complementing rich Victorian home colors. While truly black flowers are rare, the deep, dark petals of the following plants appear black in most lighting, making them ideal for creating a monochromatic garden with a dramatic flair.
1. Violas and Pansies (Viola spp.)
Violas and pansies are excellent choices for garden borders and containers. Both belong to the Viola genus, but pansies have slightly larger petals, while violas are hardier. Cultivars like ‘Molly Sanderson’ violas and ‘Black Beauty’ pansies are known for their deep, dark blooms. To encourage more flowers, use garden fertilizer and regularly deadhead the plants.
Best For: Garden borders, containers
Hardiness Zones: Typically grown as annuals in zones 3 to 9
2. Tulips (Tulipa spp.)
Dark tulip varieties like ‘Queen of the Night’ and ‘Black Parrot’ offer some of the most striking black-like blooms. According to Ward Dilmore, a landscape designer and co-founder of Petrus Landscaping in California, mass plantings of these tulips can make a bold statement. They can also be combined with other black flowers for a cohesive look.

3. Hollyhocks (Alcea rosea)
Hollyhocks, often associated with cottage gardens, can also bring a modern twist with their dark blooms. Varieties like ‘Jet Black’ hollyhocks stand out with their deep, almost black flowers. Keep in mind that hollyhocks are typically biennials, flowering in their second year.

5. Primroses (Primula vulgaris)
While primroses are usually known for bright colors, the ‘Victorian Silver Lace Black’ variety is a showstopper with its dark petals edged in creamy white. These flowers are cold-hardy and bloom early in the spring, making them a great choice for garden borders and containers.

11. Columbines (Aquilegia vulgaris)
Columbines are beloved for their unique, nectar-filled blooms that attract hummingbirds. The ‘Black Barlow’ variety offers deep crimson, almost black flowers that bring a touch of elegance to shade gardens. These plants are easy to grow and will self-sow if the flowers are not deadheaded.
