Good for cutting

Dahlia 'Cactus Mixed' brings a mixed collection of spiky cactus dahlias for bold borders 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 90–120 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 'Edinburgh' is a bold decorative variety with rich purple petals tipped white, creating a dramatic bi-colour effect that stands out brilliantly in late summer planting.

The flowers are full and symmetrical, carried on sturdy stems above a neat, bushy plant that performs well in borders and provides striking stems for cutting.

Grow it in a sunny, sheltered site with fertile, moisture-retentive but well-drained soil, planting after the last frosts for the strongest start.

Feed and deadhead regularly through the season to keep flowers coming, then lift and store the tubers before severe winter cold.

Dahlia 'Blushing Lady' offers richly blended blooms in peach, mango and soft pink tones, bringing warmth and depth to summer borders as the flowers continue to open over many weeks.

With a compact, bushy habit and generous fully double blooms, it suits both mixed beds and cutting gardens, where the flowers add a softer, sunset palette to arrangements.

Plant tubers into fertile, well-drained soil in a sunny spot once frost danger has passed, and provide regular moisture as plants begin active growth.

Keep deadheading throughout the season to prolong flowering, and lift tubers in autumn for frost-free winter storage where winters are cold.

Dahlia ‘Seduction’ is an alluring decorative variety known for its elegant pink and purple picotee petals. Each bloom features a pale, milky-white base that is delicately edged with deep violet-pink, creating a defined and sophisticated outline.

The plant is robust and floriferous, producing a high volume of medium-sized flowers throughout the season. The distinct colouring of the petals gives the blooms a three-dimensional quality, making them pop against the dark green foliage.

Plant in full sun to partial shade, in soil that has been improved with compost. This variety is excellent for adding detail and intricacy to a border without overwhelming other plants with solid blocks of colour.

Keep the plant well-watered during dry spells and stake if necessary to support the weight of the flowers. Deadhead faithfully to ensure a display that lasts well into autumn, and protect the tubers from frost during winter.

A brilliant choice for romantic cottage gardens, ‘Seduction’ draws the eye with its intricate detailing and pairs beautifully with deep purple flowers like Salvia ‘Caradonna’ or dark-leaved Heucheras.
