Dahlia Semi Cactus Karma Corona will give you gorgeous salmon-orange blooms with soft yellow centers throughout the summer months. Strong upright stems with deep, dark-green foliage support this fantastically colored flower that blooms all summer long, making Karma Corona Dahlia a wonderful choice for a cutting flower. 36-40" tall.
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).
36-40" tall. Dahlia Semi Cactus Karma Corona will give you gorgeous salmon-orange blooms with soft yellow centers throughout the summer months. Strong upright stems with deep, dark-green foliage support this fantastically colored flower that blooms all summer long, making Karma Corona Dahlia a wonderful choice for a cutting flower. Flowers can be cut at a fairly immature stage to ensure a long vase life. Because of their strong stems, they usually need no staking. Dahlias are pest resistant and will continue to bloom throughout the season, until frost. Native to Mexico and Central America, Dahlias are easy to grow and a good choice for gardeners in hot, sunny areas but they can be grown almost anywhere in the United States. Plant in full sun, in compost enriched garden loam. Pinch excess buds and deadhead for more and larger blooms, water well during growing season, especially when grown in containers. Cold hardy in zones 8-10. In colder zones lift the bulbs in fall and store in a cool place over the 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. Read our article about How To Grow Dahlias.
Growing Dahlias: Plant Dahlia tubers after spring frosts in good garden soil with full sun. Dahlias must be protected from high winds, so we suggest you position them against a wall or be ready to stake them. Keep the plants well-watered and free of bugs, applying flower fertilizer as they grow. Your dahlias will be in full bloom by July or August, with the enormous flowers continuing to bloom until frost. As frost threatens, pull up the roots and trim off the stems. You can store the tubers in a cool dry place until the following spring.
