Dahlia Purple Gem

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 the whole bloom.

If this type of dahlia isn't for you, we have a wide-ranging selection, so why not check out our full list of dahlias for sale?

The stunning purple-shaded quilled petals are further set off by being held on burgundy stems with attractive green, divided foliage.

Purple Gem Dahlias in Your Garden...

Dahlia Purple Gem 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.

In the cutting garden, the more you cut, the more flowers you get - that's why it's important to keep deadheading in mixed flower beds, even if you're not growing them for flower arranging.
