Purple Gem: Cactus Dahlia Tubers

Enter a purple patch in gardening by growing the magnificent Purple Gem Dahlia! This deep purple, semi-cactus variety carries blooms 12cm across. As the flowers mature, the ends of the petals fade to lavender, adding a silvery sheen to the whole bloom. The stunning purple-shaded quilled petals are further set off by being held on burgundy stems with attractive green, divided foliage.

Growing Purple Gem Dahlias

All dahlias do best in deep rich soil with good drainage in a sunny spot. If it is windy they will need staking. They are greedy, thirsty plants so will need watering in dry spells, and they will always flower that little bit better if there is a bit of soluble food in the watering can once every couple of weeks.

It is generally more convenient to put support stakes in at planting time, rather than leaving it until there is foliage in the way.

Planting Companions for Purple Gem

It does well in beds alongside paler flowers and grasses - it looks best in groups of three or even five if you have the room. The magnificent flower heads look great when mixed with other dahlias in velvety tones of rich plum, deep red and near-black.
