Cactus & Bedding Dahlias

Dahlia 'Nuit d’Eté' brings spiky cactus blooms in deep red-purple tones 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 80–90 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.

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.

Dahlia ‘Platinum’ is an elegant decorative variety that graces the garden with pristine white blooms, often touched with a whisper of lilac or cream at the heart. Its sophisticated form and clean colour make it a versatile addition to any planting scheme, acting as a palate cleanser amongst brighter colours.

This variety grows into a sturdy bush with broad, lush leaves that provide a dark green backdrop for the luminous flowers. The blooms are waterlily-esque in shape, with broad, slightly cupped petals that create a serene and structured appearance.

Plant in a sunny, open spot in fertile, well-drained soil. It appreciates a position with good air circulation to keep the foliage healthy and free from mildew later in the season.

Water consistently, directing moisture to the base of the plant rather than the foliage. Lift the tubers after the first frost blackens the leaves, clean them off, and store them in a frost-free environment for replanting next spring.

A brilliant choice for sophisticated, neutral borders, ‘Platinum’ brings a sense of calm and purity to the garden, glowing softly in the twilight and mixing effortlessly with all other colours in the vase.

For best results, start tubers in pots from March or April in a frost-free place, then plant out once the risk of frost has passed. Choose full sun and a warm, sheltered position, and mix in plenty of garden compost to improve structure and drainage.

Plant tubers about 10–15cm deep with the ‘eye’ facing upwards, spacing plants roughly 45–60cm apart. Keep the soil evenly moist as shoots develop. If you’re growing taller stems or larger flower heads, add a cane early so support is in place before flowering.

Water deeply in dry weather and feed every two to three weeks through summer with a high-potash fertiliser to encourage buds. Deadhead regularly and cut stems often—removing spent blooms helps direct energy into new flowers, giving you a longer, heavier display.

Dahlia ‘Park Princess’ is a charming semi-cactus bedding variety that packs a punch of bright pink colour into a compact, manageable size. Unlike its taller cousins, this variety is perfectly scaled for pots, window boxes, and the front of garden borders.

Forming a neat, low-growing mound of healthy green foliage, it produces a profusion of spiky, vibrant pink flowers that cover the plant throughout the summer. Its shorter stems mean it rarely requires staking, making it a low-maintenance option for busy gardeners.

Plant in full sun for the best flowering density, in high-quality potting compost if growing in containers. Ensure container-grown plants have excellent drainage to prevent the tubers from becoming waterlogged.

Water daily during hot spells if planted in pots, as containers dry out quickly. Deadhead faded blooms regularly to keep the plant looking tidy and to encourage new buds to form continuously until autumn.
