This grower is sure of this plant identification.
My dahlias have flourished over the years and I don't have room for all of them any more! I'll be lifting them for winter in the next few weeks - if anyone can give them a good home you are welcome to them. I'd prefer if you could pick up (near Penhow) or I could meet up with you in Newport / Chepstow / Caldicot if necessary. You are welcome to visit to see them before they get cut down and lifted, just let me know.
Dahlia genus. This genus has upright and bushy, early summer and early autumn flowering, tuberous, deciduous annuals and perennials. They bear pinnatifid or pinnatisect, mid green leaves and disc-shaped flowers.
They are half hardy to hardy and will need a sunny position with well drained soil. In frost-free areas, the plants may be left in the ground as normal herbaceous perennials, but they will benefit from regular propagation to maintain vigour. After flowering in areas with frost, lift tubers and store in a frost-free place; replant once all frost danger has passed.
Grown as bedding plants or for their flower heads, which are good for cutting or exhibition. Suitable for coastal conditions.
