USDA Hardiness Planting Zones

To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low temperatures; the lower the zone number the colder the winter.

If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will survive the winter temperatures in your area.
If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack of freezing winter temperatures do not provide a time for winter dormancy (rest).

Details

(48-60" tall) ‘Polar Bear’ Gladiolus blooms with bright white, gently ruffled petals. In early to mid-summer, long flower spikes will emerge over the sword-shaped foliage, blooming from the bottom up. This flowering habit makes Gladiolus an excellent cut flower, as fading blossoms can be removed from the stems, allowing them to remain fresh in the vase for much longer. Planted 6 inches deep at a rate of 12 per square foot in loose, well-drained, sunny soils, the corms will quickly develop sword-like green leaves in late spring. Light staking or protection from wind is recommended. Gladiolus are perennial in zones 8-10. At the end of the season, cut back the stems, mulch well, and look forward to years of enjoyment as the corms will increase with time. In cooler zones, the corms can be brought inside and stored over winter.

Planting Guides

Summer Blooming Bulbs, including popular varieties such as gladiolus and dahlias, are planted in the spring and bloom in the summer. Most of these bulbs are tropical and require warm weather to be planted. There must not be any danger of frost and your ground temperature must have reached 55 degrees Fahrenheit before planting. Many of our summer blooming bulbs can be planted as perennials in zones 9-10 (zone 8 if mulched), but should be treated as annuals in cooler climates. You can lift them and store them in the fall, or bring patio pots inside before frost. See page 15 of our Planting Guide for a bulb depth planting illustration.

Growing Gladiolus: After spring frosts are over, plant the gladiolus corms (bulbs) in your flower bed wherever you want brilliant color in mid-summer. Gladiolus take very little space in the garden and can easily be planted between other plants. After planting, keep the bulbs watered regularly. Soon you’ll have bright sword-like foliage and brilliant blooms. Gladiolus corms are inexpensive, and provide excellent color for the cost. As frost threatens, you can just forget them, and replace them with new bulbs next growing season, or dig up the corms and store them in a cool try place until the following spring.
