Summer Bulbs & Plants

Dahlia 'La Luna' brings luminous dinnerplate blooms blending creamy white with yellow flashes 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 110 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.

Zantedeschia Mixed brings a lively mix of calla lilies in bright, contrasting colours on tall stems above neat, arrow‑shaped leaves. Expect a varied palette, so every planting feels a little different. The flowers are actually a smooth ‘spathe’ wrapped around a central spadix, giving that iconic trumpet shape that suits both classic and contemporary gardens.

These summer-flowering rhizomes are outstanding in patio pots, where you can keep the compost evenly moist and enjoy the flowers up close. They also work in sheltered borders, especially in richer soils, and the clean, architectural blooms pair beautifully with grasses and airy annuals.

Plant in spring once the ground has warmed and the risk of frost has passed. Set rhizomes 5–10 cm deep, with the growing points facing up, and space them so the clumps can expand. You’ll usually see shoots appear within a few weeks, followed by flower stems through mid to late summer.

Calla lilies love moisture while they’re growing, so water regularly and feed in containers for the best display. Mulching the soil surface helps reduce drying out in warm weather. If you’re cutting stems, pick as the spathe unfurls and place straight into fresh water for long-lasting arrangements.

These are tender plants in the UK, so protect them from frost. After flowering, let the foliage die back naturally so the rhizome can recharge. In autumn, lift and store the rhizomes somewhere cool, dry and frost‑free, or move pots under cover, ready for replanting next spring.

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 'Impression Fabula' is a compact collarette-style dahlia with pink outer petals framing a bright white collar, giving it a lively, open look that suits borders, patio pots and pollinator-friendly planting.

Although smaller in stature than many dahlias, it flowers generously and steadily, making it a useful choice where long colour is needed without too much height.

Plant in a sunny, sheltered position after the last frosts, using fertile, well-drained soil and regular watering while growth gets underway.

Deadhead to maintain continuous flowering and lift tubers in autumn where winter cold is severe.
