The gladiola, also known by its genus name of Gladiolus, stands up to 3 feet tall and has trumpet-shaped flowers that open along the stalk of the plant. The gladiola is grown in a variety of colors.
The gladiola is a perennial plant grown from a bulb planted in well-drained soil during the spring, after all danger of frost has passed. The gladiola requires full sun exposure and at least 1 inch of rain per week.
After all the flowers have faded, they should be pinched off and stalks should be cut back so that the plant can produce energy for the bulb for the next growing season. In warmer zones, the bulbs can be mulched over the winter; in colder areas, they should be dug up and stored until the next spring.
