Dahlia Purple Gem
Availability: Out of stock
Dahlia 'Purple Gem' is an outstanding variety of cactus type Dahlia. It has long, narrow, almost spiky petals that are of the most incredible colour. A deep-purple flower that is very bright and very bold, the perfect companion for rich plum, purples and near-black flowers. Makes exquisite cut-flowers, remove spent flowers promptly to encourage longer and more productive flowering. Will bloom from mid-summer right through to mid-autumn. This is a real purple Gem and would bring bold colour wherever you choose to plant it. Will reach a max height of around 90cm.
Supplied as tubers, the best time to plant is in April and May. To plant them, dig a hole at least 20-30cm square and around 20-30cm deep for each one. Cover the base of the hole with 10cms of compost, or manure and give it a good dousing with a full watering can and then plant the dahlia at a depth of 15-20cms. You will need a stout stake, not just a bamboo cane, to support each plant and it is a good idea to knock this in first and then place the plant by its side. It will need to be lifted in winter - once the foliage dies back simply dig it up and store in a cool, frost free location.
