If you are looking for a black dahlia, the closest you will come to the dark, sooty colour is an Arabian Night dahlia. The Arabian Night dahlia is a deep black-purple flower that appears black in direct sunlight. It also has tones of deep crimson. Plant Arabian Night dahlias in flower beds or use them to form a border around your garden. Make sure your flower bed soil remains moist to produce these unusual blooms.

Identifying the Arabian Night

Recognise the black-toned Arabian Night dahlia by its deep, rich purple-red-black tone. They have broad petals and resemble water lilies. The Arabian Night dahlia's foliage is a deep green. The plant can grow up to about 4 feet tall.

Growing Conditions

The American Dahlia Society advises that your garden bed should have access to partial to full sun. You will need to water your dahlias frequently to keep the soil moist. The Arabian Night dahlia can bloom all the way until the first frost of your season, but a heavy coat of frost will kill the flower.

Cutting Dahlias

The American Dahlia Society lists the Arabian Night dahlia as one of the best dahlias types to cut and put into vases. The flower has a sturdy stem, few side shoots and an ability to open in a vase of water even when cut at an immature stage.

Soil Types

Arabian Night dahlias are highly adaptable to different types of soils, including sandy clay, clay, and loamy clay or sand soil mixtures. They can grow in pH ranges from 5.0 to 8.5, according to the Plant Database. The soil should have adequate drainage so that the dahlias do not rot.
