Black flowers and foliage appeal to gardeners who like to try new things. Black flowers are sophisticated: 'Black Gem' cornflower and 'Superstition' iris, for instance, look almost dangerous next to their paler sisters. Black enhances other colors. It draws the eye, declares Karen Platt, author of Black Magic and Purple Passion (Black Tulip Publishing, November 2004) and founder of the International Black Plant Society. Black can be an exclamation mark in a sea of silver, for example. Responding to demand, growers are developing ever-darker varieties, including old favorites such as sweet peas and coleus.
Picking the Plants
Even those of us who adore black plants find that choosing them is sometimes a bit of a challenge. So I asked gardeners growing black plants to share which they like best and how they use the dark varieties in the garden.
Tulip: 'Queen of Night' is a near-black tulip that looks great mixed with something pale like tulip 'Angelique' (a pale pink, peony-flowered variety).
—Barbara Damrosch, author of The Garden Primer (Rodale, 2003)
Hellebores: I appreciate black and dark red hellebores because they hold their color long after paler pinks and whites have faded to green in the spring heat. Black-flowered hellebores are luscious, but against the bare soil of late winter, they disappear. To make them stand out, I combine them with pale-flowered bulbs and glowing foliage. Snowdrops and winter aconite bloom as the hellebores are opening. Both set off the dark flowers with their pure, bright colors. Later in the season, I use white variegated or yellow sedges such as golden woodland sedge.

Violas: I grow black Johnny jump-ups and let them self-sow around pale yellow primroses and golden feverfew.

Shrubs: I use Physocarpus 'Diabolo', Weigela 'Wine and Roses', and Sambucus 'Black Beauty' to complement the perennials and to help tie the garden together. My favorites all grow well in my zone and do not require spraying, extra fertilizer, or staking. Plants that need the "intensive care unit" to survive do not make for a sustainable garden.

Mondo grass: I have a much-loved, incredibly slow-growing black mondo grass in an old Japanese pot—it's a great container plant.

Vegetables: I would grow some of my favorite black vegetables for their magnificent color alone. The tomatoes 'Black Cherry', 'Black Plum', and 'Black' are stunning on a plate. The color of the ornamental peppers 'Purple Delight' and 'Royal Black' is a saturated ultramarine violet. And the pumpkins 'Futsu' and 'Yokohama' are gorgeous traditional Japanese varieties.
