Gladiolus 'Atom' produces bright orange-red flowers edged in silvery white on elegant flower spikes that add height and movement to summer borders. The blooms open gradually from the base upwards, giving a long display and plenty of stems for cutting.

Growing to around 60–90 cm, this gladiolus forms upright, sword-like foliage and neat clumps that suit mixed planting schemes. It’s ideal for weaving through perennials or planting in small groups for a natural, airy look.

Plant corms in spring once the soil has warmed, choosing a sunny, sheltered position in well-drained soil. Work in compost and avoid waterlogged ground, which can rot corms before they establish.

Water during dry spells and keep the area weed-free while shoots emerge. In exposed sites, a simple support helps keep flower spikes upright. Deadhead spent blooms, but leave the foliage to feed the corm for next year.

Excellent as cut flowers and perfect for summer colour, gladioli also attract pollinators when grown in mixed borders. Lift and store corms after foliage dies back in colder areas, or mulch well where varieties are hardy.

Galanthus nivalis is a reliable spring bulb for natural drifts and small pockets of early colour. Supplied “in the green”, it arrives with foliage attached so you can replant it soon after flowering, which can help it settle in faster than dry bulbs.

These plants are perfect for lawns, borders, and woodland edges where they can return year after year. In late winter, nodding white flowers with green touches appear on short stems, often pushing through frost. They’re especially striking when planted in generous groups and allowed to naturalise.

Plant promptly into soil that stays moist but drains well, ideally enriched with leaf mould or garden compost. Keep each clump at the same depth it was growing previously, then firm the soil around it. Water in well to settle roots and remove air pockets.

Once established, maintenance is simple. Let the foliage die back naturally so the bulb can store energy for next season’s display. Where planted in grass, delay mowing until the leaves have fully yellowed and collapsed.

For the most natural effect, repeat the planting in several small drifts and vary the spacing slightly. Snowdrops pair well with winter aconites and early narcissus, and they’re excellent for underplanting deciduous trees. With the right conditions, clumps will slowly broaden over time into a more generous seasonal carpet.

Anemone × hybrida ‘Honorine Jobert’ is a classic Japanese anemone prized for elegant, semi‑double white flowers on tall, wiry stems from late summer into autumn. The clear white blooms brighten borders and work beautifully in twilight gardens. Each flower has a bright boss of yellow stamens for contrast.
