Sword Lily (Gladiolus x hortulanus) - Description
Gladioli are attractive perennials with sword-shaped leaves and spikes of many colorful blooms.
Sword Lily (Gladiolus x hortulanus) - Blooming
For best flowering, it is important to treat your corms with TLC during the whole year.
Sword Lily (Gladiolus x hortulanus) - Growth
Grow in full sun. They do not do well when the roots are crowded by other plants or a building foundation. If there is any danger of freeze in the winter, dig them up at the end of the growing season and dry, treat for insects if needed, and store in a frost-free, cool, location. Remove cormlets at this time.
Sword Lily (Gladiolus x hortulanus) - Planting
Plant corms of tender glads in spring as deep as four times their size. Hardy glads, including G. communis, can be planted in spring or fall. Gladiolus will produce more corms, and should be planted about 7" apart for the largest corms. Plant a handful of corms at a time and once per week to see color all season long.
Sword Lily (Gladiolus x hortulanus) - Pest
The worst pest is a small winged insect called a thrip. Make sure corms are clear of them before planting, and dust plants once a week starting when leaves are 6" tall through flowering.
