No Staking Required
Gladiolus Hardy Byzantinus, with its elegant flowers in vibrant magenta, scramble up straight stems opening from the bottom up. Shorter than classic varieties, it may not need staking. A perfect height for the middle of your sunny border. It is said to be hardy in zone 5/6 when well mulched for winter. However, for guaranteed winter survival, like other less hardy Glads, we recommend lifting in zones 3-7. *NOTE: Bulbs will need to be lifted in fall in zones 3-7.

Gladiolus General Information

Gladioli are a mainstay in the florist industry. The National Gardening Bureau has declared 2022 as the “Year of the Gladiolus”. Gladiolus commonly called “Glads” are a great cut flower for spectacular summer bouquets. Available in a rainbow of colors: yellow, pink, lavender, rose, burgundy, white and green. Flowers scramble up the stems, opening from the bottom up, above sword-like foliage to provide beautiful vertical accents. They typically reach between 2-5’ with flowers ranging in size from 3” in diameter to 5” across. All our accent annuals are guaranteed to reach you in good condition and to grow, but we can't guarantee annuals to overwinter. Will be an annual except in zones 8-10 but can be stored over the winter in colder zones. Instructions

Gladiolus Plant Care

Hardy in Zones 8-10. Plant Gladioli in full sun in well-drained soil after the last frost date. Mix compost (humus) into soil with a garden fork or tiller to loosen soil to about 1 foot deep to improve consistency and fertility. Extend the Gladiolus season by planting in two-week intervals until June. Plant 4-6” deep with pointed end facing up. Space about 6-8” apart. Water thoroughly at planting. Taller varieties usually need to be staked. Be careful bulbs are not damaged with the stakes. In zones 7 and colder, lift in fall when foliage has declined after the first fall frost. Place in a dry, frost-free place over winter. A paper or cloth bag, onion bag or nylon pantyhose works well. They may also be stored in single layers in cardboard boxes with newspaper between layers or on screens.
