Description

A classic award-winner, Dahlia 'Duet' has been a star performer in summer gardens since 1955. Some beauties just don’t go out of style, and this one is one of those. Dependable in the colours it produces, and supported with strong stems which keep its star blooms up straight, it is a favourite for shows, where it still sometimes outdoes its younger dahlia siblings!

Dahlia 'Duet's medium sized bi-colour 20cm bloom tips its wine red petals with pure white. The petals' edges turn slightly downwards, preventing the collection of rainwater in inclement weather and increasing their ability to stay tall and erect after rain.

Dahlias in 60 seconds

Dahlias like full sun and a free-draining soil, and should be lifted and stored in winter, or at least protected with peat or straw. Dahlia flowers can range from 5 to 25cm in diameter and those magnificent larger-flowering dahlias might appreciate a little extra support with canes!
