HORTICULTURE

Detailed explanation-1: -Gladiolus is propagated by corms (the underground storage organs-which are sometimes wrongly called as bulbs) and cormels. The cormels of the first year would be normally of very small size and would not yield any flowers.

Detailed explanation-2: -Like many perennial plants, gladiolus grows from a large bulb each year, then dies back and regrows the following year. This “bulb” is known as a corm, and the plant grows a new one right on top of the old one each year.
