Description
Introduced by Swan Island Dahlias in Oregon, USA, Dahlia 'Hootenanny Swan Island' offers the usual quality we have come to expect from this world-renowned, family-run business. Its flowers are a vibrant magenta, with a tousled ring of narrow, white-streaked petals around a golden-yellow centre. We adore Dahlia 'Hootenanny Swan Island' as it provides all the beauty of a single-flowered cultivar with its own subtle dash of cultivated glamour. The velvety red tones work beautifully alongside other rich, jewel-like colours such as purples and oranges.
For the most impressive results, we recommend planting your 'Hootenanny Swan Island' dahlias in generous groups of five or more. To bulk up your collection, why not try taking cuttings? Using the new shoots in early spring, simply snip a few off once they are about 8cm tall and insert in a pot of free-draining compost. Given warmth, light, and regular misting, roots should appear out of the bottom of the pot within a few weeks.

Useful information
-
Dahlia 'Hootenanny Swan Island' is half hardy, which means that it should be kept frost free over winter and during spring.
For best results, start your dahlia tubers in temporary pots in a
greenhouse in March or April to grow on to transplant outside later in the season—this will give them a head start.Alternatively, you can plant the Dahlia 'Hootenanny Swan Island' tubers directly outside in May.
Plant with the stump of last year's stem facing upwards. The tuber should be fully submerged but with the stump just below the soil surface.
Plant one tuber per 8-10" pot if growing on during spring. When
planting outside, space the tubers around 30-50cm apart from each other. Compact varieties don’t need so much space.Water-in thoroughly after planting and continue to water regularly once in full growth, but only when the soil appears to be nearly dry.
