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.

Dahlia 'David Howard' is a summer-flowering dahlia grown from a tuber, loved for burnt-orange blooms set against dramatic bronze-purple foliage. 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. Bronze-tinged leaves make the orange blooms stand out.

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 0.5–1 m with a spread of around 0.1–0.5 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.

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.

Dahlia ‘Just Married’ is a romantic decorative variety renowned for its soft, dreamy blend of bright pink and creamy white. It is a favourite for wedding floristry and elegant garden designs, offering a delicate and sophisticated look that blends seamlessly with other pastel shades.

This variety produces an abundance of medium-sized flowers on long, straight stems, making it exceptional for cutting. The petals are slightly fimbriated (fringed) at the tips, adding a unique, ruffled texture to the blooms that softens their overall appearance.

Plant in full sun to partial shade, ensuring the soil is fertile and well-worked before planting. It thrives in a dedicated cutting garden or mixed border where it can be easily accessed for harvesting stems.

Keep the soil consistently moist during summer, as water stress can reduce flower quality. In late autumn, cut back the stems and lift the tubers to store in a cool, dry place until spring, ensuring they are kept frost-free.

A brilliant choice for bridal bouquets and romantic garden themes, ‘Just Married’ bridges the gap between white and pink planting schemes, providing reliable structure and charm from mid-summer to autumn.

Dahlia 'Verrone’s Obsidian' is an orchid-form dahlia with starry, near-black blooms and a bright yellow centre. The open shape gives a modern look in the border and can be easier for pollinators to use than densely double dahlias—ideal for a dramatic cutting garden.

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.

After the first frosts blacken the foliage, cut stems back and lift the tubers to store somewhere cool, dry and frost-free. In very mild areas you can mulch heavily, but lifting is safest. Replant next spring and you’ll usually see stronger plants each year.

Dahlia ‘Black Jack’ is a dramatic cactus variety that commands attention with its spiky, dark maroon petals that appear almost black in certain lights. It adds instant depth and mystery to the garden, serving as a perfect counterpoint to brighter, lighter blooms in a mixed herbaceous border.

This variety forms a bushy, upright plant with dark, lush foliage that enhances the moody intensity of the flowers. The pointed, tubular petals radiate outward, giving the blooms a star-like quality that adds texture and architectural interest to planting schemes.

Plant in full sun to help the dark pigments develop fully, ensuring the soil is rich in organic matter and well-drained. Like all dahlias, it appreciates a feeding of high-potash fertiliser once blooming begins to sustain its performance.

Support with stakes as the plant grows, as the stems can become top-heavy with flowers. Remove spent blooms to keep the plant tidy and productive, and lift tubers in autumn to protect them from freezing temperatures.

A brilliant choice for contemporary and gothic-inspired gardens, ‘Black Jack’ looks stunning when planted alongside lime-green foliage or bright orange flowers, creating a bold, high-contrast display.

Dahlia 'Bishop of Llandaff' is loved for the contrast of bright red flowers against very dark foliage. It’s a classic choice for cottage borders and cutting beds, and it flowers from summer into autumn. This variety also carries the RHS Award of Garden Merit.

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.
