- Description
-
Fragrant gladiolus is a flowering bulb native to Africa in the iris (Iridaceae) family. The Genus name comes from the Latin word for a small sword in reference to the leaves. The graceful 6-petaled flowers are fragrant and open successively on nodding stems The foliage grows in the typical fan shape of irises. The plant can reach 2-3 feet in height.
This plant does best in full sun in moist soil with good drainage. Protection from strong winds is helpful. As this is a later blooming bulb it can be mixed with the earlier blooming ones to prolong the season. Use in the border of garden beds or containers. Be sure to provide water during dry spells.
Corms are planted after the first frost or started indoors for earlier blooms. Depending on the size of the corm, they should be planted 2-6 inches deep and 6-8 inches apart. Planting in groups of at least 5 gives the best effect. The coms can be left in the ground over winter in zones 7-10 but will need to be lifted in colder climates. Allow the foliage to yellow before cutting it back.
Insects, Diseases, and Other Plant Problems: Susceptible to botrytis, crown rot, rust, wilt and mosaic virus. Watch for aphids, mealy bugs, spider mites and thrips. Avoid heavy clay as corms will rot.
