General Description

Few garden plants rival dahlias as everblooming bedding plants and cutflowers. The breathtaking 'Arabian Night' is a herbaceous, warm-season, tender perennial with bulbous underground tubers. Its compound green foliage is made of oval and pointed leaflets with toothed margins. The 3- to 4-inch (8 to 10 cm), formal decorative flowers are dark red-crimson and long-lasting. The oval petals overlap each other in multiple rows to form a full (double form), perfect flower head. It is good to remove the spent flowers to encourage continued flower production up until frost. The hybrid 'Arabian Night' was introduced in 1951.

Dahlias prefer well-drained, fertile soil and full to partial sun. The most beautiful flowers occur when nights are comfortably cool and days warm and sunny. Hybrid dahlias are often grown from divisions of tuberous roots and cuttings to preserve their unique characteristics. Dahlias are cold sensitive and their tuberous roots should be lifted and overwintered in cool dry locations where winters are harsh. In hot, humid subtropical regions the dahlia is best grown in the late fall and winter with the start of the dry season.
