Gladioli

Gladiolus callianthus (often sold as acidanthera) produces elegant, starry white flowers with a rich, red-purple throat that adds a refined, exotic feel to late-summer borders, patio pots, and cutting gardens.

Reaching an established height of around 80–100cm, it sends up slender stems lined with multiple buds that open in succession, extending the display over several weeks and providing excellent cut flowers.

Plant corms in spring once the soil has warmed, in a sunny, sheltered position with fertile, well-drained soil. In heavier ground, plant on a gritty layer or grow in containers for sharper drainage.

Water after planting and during dry spells while growth is active, then feed every two to three weeks once stems develop. Taller stems may benefit from discreet support in windy gardens.
