GLADIOLUS

Gladiolus is a tall, slender perennial that grows from a corm and is often treated as an annual. It provides wonderful color and accents in our summer gardens and makes lovely cut flowers. Plant them in groups in the mid-height or taller flower borders, or put them in rows in a cutting garden. Gladioli often live through our milder winters but may require lifting in the fall.
