Summer Bulbs & Plants

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 'Café au Lait Twist' is a dinnerplate-style decorative dahlia with creamy petals and a lively pink ‘twist’ that makes every flower slightly different. The big heads are brilliant for bouquets and statement pots, and the plant keeps flowering right up to the first frosts.

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 'Sir Alf Ramsey' brings large dinnerplate blooms in purple and white 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.

Grow in dappled or partial shade in moist, humus-rich soil. Astilbes dislike drying out, so they perform best where the soil stays evenly moist, including near ponds or in consistently watered borders.

Water during dry spells, mulch in spring to conserve moisture, and cut back spent flower stems if you prefer a tidy look. Alternatively, leave seedheads for gentle texture into autumn.

Ideal for shady borders and waterside planting, ‘Bonn’ combines beautifully with hostas, ferns and brunnera. The plumes also make charming stems for cutting or drying.

Dahlia ‘Rainbow Silence’ is a delightful decorative variety that features a harmonious blend of soft peach, lilac, and yellow tones. The petals transition gently between these warm, sunset hues, creating a multifaceted bloom that looks different from every angle.

This variety forms a bushy, medium-height plant with strong stems that display the flowers well above the foliage. The blooms are fully double and rounded, offering a classic dahlia shape with a modern, pastel colour twist.

Plant in a sunny, sheltered position in moist, fertile soil. The complex colouring of the petals is best appreciated in a spot where the flowers can be viewed up close, such as near a path or patio.

Water regularly during the growing season and apply a balanced liquid feed every couple of weeks once the buds appear. Remove spent flowers to channel energy into new growth and lift the tubers for winter storage in colder regions.

A brilliant choice for pastel-themed gardens, ‘Rainbow Silence’ provides a soft, glowing presence in the border and makes a wonderful cut flower that bridges the gap between pink and yellow arrangements.

Anemone nemorosa 'Blue Eyes' is a woodland classic, bringing white flowers with a sky-blue eye to shady corners in early spring. The starry blooms appear in a fresh carpet above finely cut foliage, brightening banks, underplanting and the front of borders when little else is flowering, and they look especially beautiful planted in repeating groups.

Reaching about 15–25cm in flower, wood anemones spread steadily to form natural-looking colonies. They are ideal for planting beneath deciduous trees and shrubs, where they enjoy spring light before the canopy closes, and they naturalise beautifully in woodland-style gardens.

Plant rootstocks in autumn or early spring in humus-rich, moist but well-drained soil. A position in partial shade is ideal, though they will tolerate sun in cool, damp ground. Water after planting and keep soil just moist while new growth establishes.

Once settled, wood anemones are low maintenance. Leave foliage to die back naturally after flowering so plants can recharge for next year. A light mulch of leaf mould or compost in autumn supports healthy colonies and helps retain soil moisture.

Use wood anemones to create spring drifts under shrubs, along pathways and on woodland edges. The flowers are pollinator-friendly and provide early nectar, while the spreading habit helps knit planting together for a soft, natural finish.
