Native to Mexico, it's no surprise that dahlias like a sunny spot. Give them fertile, free-draining soil and you'll have happy tubers. Dahlias vary widely in their flower shapes and colours and offer huge interest for any gardener growing them.
Popular with Victorians, growing somewhat out of fashion in the latter part of the 20th century, Dahlia tubers are back with a botanical bang and seen everywhere from the RHS Chelsea Flower Show (where they are forced to flower early) to the RHS shows at Hampton Court and Tatton Park where, in 2019, borders full of dazzling dahlias were on hand to welcome visitors.
More compact varieties are used for bedding plants, but the ones that really take your breath away are the taller specimens with large blooms, bound to impress.
The Dahlia on every high end horticulturalist's list is 'Cafe au Lait' - a true beauty - a creamy coffee colour - it is much prized as a cut flower and very respected in the industry. Sophisticated and stately, one not to miss.
Cactus dahlias are very popular for their quirky shaped blooms - 'Park Princess' is a perfect example, befitting of its royal name and a reliable purchase from royal warrant holders, Suttons! Meanwhile 'My Love' makes an excellent gift to a loved one in pure delicate white. Partner with pink and white Cosmos for a delicious combination.
It is important to regularly dead-head dahlias in order to maximise flowering. Some taller varieties may require staking. (Link to 38cm plant support rings).
Pompom types look neat, their spherical blooms perfect for picking. 'Golden Scepter' will brighten any border.
Dahlia tubers need to be lifted and stored over winter after flowering. Keep in a little dry soil or sand in a frost free environment before planting out again in late spring.
For the largest of all Dahlia blooms, head to our Dinner Plate Mix - a selection of decorative blooms in a mass of colours, with flowers of up to 25cm diameter. Great fun for children and an alternative to sunflowers!
