About Gladiolus
Gladiolus hybrid is a fast-growing bulb in the Iridaceae family. It reaches around 1.2 m tall and 20 cm wide at maturity, with deciduous foliage. Red, pink, yellow, orange, purple and white flowers appear in summer.
Where to grow Gladiolus
Gladiolus suits warm-temperate, subtropical and Mediterranean climates and grows best in full sun. It is frost tender, so protect it from hard frosts or grow it in a sheltered spot or pot.
Soil & planting
Most soils suit Gladiolus provided drainage is reasonable. Plant into well-prepared ground, firm the soil around the roots and water deeply to settle it in.
Watering & feeding
Gladiolus does best with regular, moderate watering. Apply a balanced fertiliser in spring to support healthy growth. Check moisture below the mulch during establishment and water thoroughly when needed rather than following a rigid schedule.
Pruning & care
Prune Gladiolus after flowering to keep it compact and encourage the next flush of blooms. Its ongoing care level is moderate maintenance.
Using Gladiolus in the garden
Gladiolus earns its place for cut flowers for the vase and a feature or specimen planting.
Companion planting & design
Build the planting around neighbours suited to the same regular, moderate watering and warm-temperate climate as Gladiolus. Repeating the foliage or flower colour nearby will make the composition feel deliberate.
Good to know
Be aware it can self-seed or spread into bushland in some regions — check it is not a declared weed in your area before planting.
