Plant half-hardy hybrid gladiolus corms directly outside in mid to late spring, or start them under cover earlier. Hardy naturalising types, including Gladiolus byzantinus, can be planted in autumn or spring. Always plant corms during the season in which they arrive.

'Ivory Perfection'
sword lily
Gladiolus 'Ivory Perfection' lives up to its name with an air of quiet sophistication and timeless beauty. From neat fans of green, sword-shaped leaves rise tall, elegant stems adorned with up to ten flawless ivory-white blooms. Each flower seems to glow softly, catching the light like fine porcelain and bringing an effortless calm to the late-summer garden. The purity of its colouring makes Gladiolus 'Ivory Perfection' an exquisite choice for creating serene, harmonious planting schemes or for adding contrast among richly coloured perennials.
Flowering from late summer into autumn, Gladiolus 'Ivory Perfection' offers a graceful finale to the season. Its tall, sturdy stems make it perfect for cutting, where its pristine blooms lend a sense of freshness and refinement to any bouquet. Easy to grow in well-drained soil and full sun, this white sword lily is both elegant and reliable—proof that sometimes the simplest palette is also the most striking. Gladiolus 'Ivory Perfection' is a true classic for those who value poise and purity in the garden.

Plant calendar
Grow gladioli in full sun, in a sheltered border or large patio container. They need free-draining conditions, so improve heavy soil with organic matter and grit or plant into a raised bed. For containers, use peat-free multipurpose compost.
Position each corm with its pointed side facing upwards, around 10–15cm deep. Space them approximately 10cm apart when planting in groups. A generous cluster creates a fuller display and allows the flower spikes to offer one another some support.
Water thoroughly after planting, then allow the soil to become nearly dry between waterings while the corms remain dormant. Once shoots appear, water regularly throughout active growth, particularly during warm, dry weather and when growing gladioli in containers.
Most gladioli remain upright without help, although staking is useful in exposed or windy positions. Remove faded flower spikes just above the foliage, then leave the leaves to die back naturally. They can be cut down to ground level in autumn.
Lift half-hardy hybrid gladiolus corms in autumn and store them somewhere cool, dry and frost free. These varieties often give their strongest display in their first year. Hardy naturalising gladioli can remain outdoors where the soil drains freely and does not become waterlogged.
