Dahlias

Dahlia 'Picking Garden Mix' brings a surprise mix of colours and flower forms for bouquets to summer borders and cutting gardens, with bold flowerheads held on sturdy stems. Whether planted in drifts or dotted through mixed beds, the blooms add instant impact and keep coming through the warm months.

Once established, this clump-forming dahlia typically reaches 80–120 cm, producing plenty of long stems for cutting. Regular picking and deadheading encourages a steady succession of flowers from midsummer into autumn.

Start tubers in a frost-free place in spring, or plant outside once the risk of frost has passed. Choose a sunny, sheltered spot in fertile, humus-rich, well-drained soil, and enrich the planting area with compost for best results.

Water during dry spells, especially while buds form, and feed every two to three weeks through the flowering period. Taller plants benefit from discreet staking, and removing faded blooms keeps the plant productive and tidy.

Perfect for borders, patio pots and cutting gardens, dahlias are also pollinator-friendly in single-flowered forms. Lift and store the tubers after the first frosts in colder areas to enjoy an even better display the following year.

Dahlia 'Bohemian Spartacus' is a summer-flowering dahlia grown from a tuber, loved for rich red petals streaked and flamed with golden yellow. The fully double, show-stopping blooms sit above fresh foliage and bring instant impact to borders, cutting gardens and large pots.

Flowers appear from mid-summer until the first frosts, especially if you keep deadheading. Dahlias are excellent cut flowers—snip stems regularly to encourage new buds. The streaked petals give each bloom a different fiery pattern.

Plant in fertile, humus-rich soil in a sunny, sheltered position. Start tubers in pots under cover in March or April, then plant out after frost risk has passed, or plant directly outside in May. Set tubers about 10–15cm deep and space plants 45–60cm apart.

This variety typically reaches 1–1.5 m with a spread of around 0.5–1 m. Taller types benefit from staking in windy spots. Water during dry spells and feed with a high-potash fertiliser every couple of weeks once buds form.

In autumn, once frost blackens the foliage, cut stems back and lift tubers to store cool, dry and frost-free. In very mild areas you can mulch and leave them in the ground. Replant in spring for another season of colour.

Dahlia ‘My Love’ is a classic semi-cactus variety that produces elegant, pure white blooms with a hint of lime green at the centre. Known for its vigour and reliability, it is one of the most popular white dahlias for both garden display and cut flower use.

Reaching a tall stature, this variety sends up long, strong stems topped with spiky, needle-like petals that give the flower a starburst effect. Its height makes it an excellent candidate for the back of the border, where it can rise above lower-growing perennials.

Plant in full sun to keep the white petals bright and crisp, in well-drained, fertile soil. Due to its height, it is essential to stake this variety early in the season to prevent wind damage.

Water deeply once a week during dry periods and feed with a liquid tomato fertiliser from July onwards. When the season ends, lift the tubers and store them in dry compost or sand to overwinter safely.

A brilliant choice for "Moon Gardens" or all-white schemes, ‘My Love’ reflects evening light beautifully and serves as a versatile, long-lasting cut flower that complements any arrangement.
