This entry has yet to be reviewed and approved by L2G editors.
Few garden plants rival dahlias as everblooming bedding plants and cutflowers. The single-form, daisy-like dahlia 'Delta Red' produces 4-inch (10 cm) flowers on long stems. Each long-lasting blossom comprises eight scarlet-red petals surrounding a central yellow disk. The dahlia is a herbaceous, warm-season, tender perennial with bulbous underground tubers. Its compound dark green foliage is made of oval and pointed leaflets with toothed margins. It is good to remove the spent flowers to encourage continued flower production up until frost. The hybrid 'Delta Red' was introduced in 2003.
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. Stake the central stems of 'Delta Red' to prevent this very tall plant from toppling in winds or rainstorms.
