The tall dahlia 'Cornwall Island' stands out for its fully double flowers in a deep, richly saturated purple. Its neatly layered petals hold their compact form exceptionally well from July through to October. This intense, cool-toned shade creates a striking contrast against pale plants and green foliage. It is a dependable, expressive variety that is best placed in the middle of garden plantings.
Tubers are best planted in spring, from April to May, once the soil has warmed sufficiently.
The recommended planting depth is 10 cm.
A spacing of 40-50 cm between plants allows them to develop freely.
This variety reaches a height of around 100 cm.
It flowers from July to October.
It is not frost-hardy, so the tubers should be lifted and stored in a cool place.
It combines beautifully with varieties bearing pale, pastel-coloured flowers, as well as with ornamental grasses that highlight its intense colouring. It is also suitable for cutting - its sturdy stems and long-lasting blooms help it remain fresh in a vase for an extended period.
