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.

    Comments about High Country Gardens Gladiolus acidanthera:

    I purchased this bulb many years ago as a new gardener. My HARDINESS ZONE IS 6b. I placed the bulbs on the south side of my home in 8 hours of summer sunshine. These bulbs bloomed prolifically for many years. I did nothing special to the bulbs--no extra mulch in winter etc. I think they're pretty tough plants.
    I am going to plant some again this year and plan to put them with Knautia macedonica and hope they bloom at the same time.

    Comments about High Country Gardens Gladiolus acidanthera:

    The bulbs had a 90% germination rate. The plants with partial shade did much better than those in the all day hot sun. The grasshoppers really chewed them up. Let's hop they overwinter and come back next year.

      Q & A

      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).
