Botanical Name

Plant Common Name

Dahlia, Unwin Series Dahlias

General Description

Dahlias in the Unwin Series are dwarf, uniform and heavy-flowering. Their colorful flowers are semi-double to double and bushy plants have shiny green foliage. These dahlias are ideal for small spaces and containers. Flower colors include orange, red, pink, violet, white and yellow.

Nothing beats dahlias as everblooming warm season bedding plants and cut flowers. These herbaceous warm season tender perennials have bulbous underground tubers. They produce colorful flowers all season, as long as weather is above freezing and not excessively hot. It is good to remove the old buds from spent flowers to encourage continued flowering.

Dahlias prefer well-drained, fertile soil and full to partial sun. Ideally, night temperatures should be comfortably cool, and days should lack overbearing heat and humidity. Dahlias are cold sensitive. In colder regions, plant after the danger of frost has passed and lift tubers before the ground freezes in autumn. In frost free zones, they can be planted in fall for continuous winter color. Those grown in the tropics should be grown in the cooler, dry season.

Compact cultivars like this are best grown in containers or along garden edges. They are most colorful and floriferous when days are warm and sunny and evening temperatures are comfortably cool.
