Dahlias are nearly unrivaled as everblooming bedding plants or cut flowers. Introduced in 1957, the hybrid 'Contraste' produces formal double-form (extra petal rows), dark red and white flowers. The flower heads attain diameters in the range of 6 to 9 inches (15 to 23 cm). These long-lasting flowers have numerous narrow petals, darkest red at their bases and then becoming white at the tips. 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 green foliage 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 the tall-growing 'Contraste' to prevent toppling.
