This dahlia is named after John Markham who was the chairperson of the Royal Horticultural Society. A keen dahlia grower. Bred by Alex Brannigan, very good variety for the exhibition bench and garden.
Dahlias require a fertile, moist but well-drained soil, and a sunny, sheltered spot. The taller varieties need staking. In autumn, dig up the tubers and overwinter them in a frost-free place, such as a greenhouse or a shed. Bring them back into growth in early April, then plant out in the garden from May onwards.
Our Dahlias are all unique varieties propagated here are the nursery. We ship them as growing plants typically 10 to 15cm high, not as tubers. This way you are sure that your plants have the best opportunity to grow and be successful. Orders placed for Dahlias are only shipped/available starting in May as we protect them for you from frost until then.
It is important to only plant Dahlias when all chances of frost have passed. When you place your order you will receive an email to confirm that we have received your order. You will then get a further email when your plants are either shipped or ready to collect from the Garden centre depending on what shipping option you picked at checkout time.
