General Description

Dahlias are nearly unrivaled as everblooming bedding plants or cut flowers. The brownish green foliage and the blooms of 'Classic Swanlake' are certainly beautiful. This hybrid, first selected in 1981, produces semi-double, peony-like flowers with a brown and gold center. The petal bases are yellow, but quickly blush to creamy ivory-white toward their edges. Multiple rows of the oval petals create the 4-inch (10 cm) flowers that lasts a long time. Remove the spent flowers to encourage continued flower production up until frost. The dahlia is a herbaceous, warm-season, tender perennial with bulbous underground tubers. The compound deep brown-purplish green foliage of 'Classic Swanlake' is made of oval and pointed leaflets with toothed margins.

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. In windy garden locations, stake the central stems of this dahlia to prevent toppling.
