Dahlia Unwins mixed is a mixture of double flowered dahlias in different beautiful and bright colours. This mixture contains a.o. flowers in yellow, red, pink, white and orange. The leaves are light green and this makes for a striking contrast with the flowers. The double flowered flowers are very well loved by bees, butterflies and other benificial insects. This mixture is very well suited for the use in borders, flower- and picking garden, in the bee- and butterfly garden, as cutflower and for the growing in large flower pots and containers. Deadhead often to ensure a longer, more beautiful and more abundant flowering season.
