Rose Supreme Gladiolus

Availability: Out of stock

Long-lasting pinkish-peachy spires, the Rose Supreme Gladiolus (Gladiolus 'Rose Supreme') are soothing vertical focal points for adding punctuation throughout the garden bed and border! You'll love the ruffled petals and slightly darker edges with lighter throats as each alternating bloom opens in turn from the bottom to the top of the 3-4 foot tall spike!

Gladiola form tight clumps of equally vertical sword-like leaves in lush green and are the perfect complement to these architectural blooms! Butterflies adore these blossoms and the occasional Hummingbird too! Plant groupings of these hardy corms throughout the landscape to feed your bees and provide you with plenty of structural flowers for tall vase arrangements!

Also known as Sword Lilies, Glads are eye-catching with their erect growth and alternating symmetry. Growing throughout USDA growing zones 8-10 as a hardy perennial bulb, the midsummer blooms work as annual accents in all other growing zones. Northern growers can dig the corms up in the fall once the foliage has yellowed and store them for the winter in a frost-free location.

Planting and Application:

Ideal sculptural accents throughout both existing garden plans and established landscapes, there are few locations that won't be able to find a few inches of room to tuck these vertically growing, space-saving corms in among the garden bed or borders plants each spring.

Long-lasting color, one spike can bloom for a couple of weeks! Want a longer display? Plant your corms in spring two weeks apart for a staggered bloom all summer! Create drifts and rows in tight spots, along paths and walkways, or against a fence line or rock wall for height and color! Perfect cottage garden and courtyard plants, these blooms have both a formal and informal look anywhere!

Rose Supreme Gladiola works great in planters and mixed containers as a spiky focal point and vertical specimen. Looking best mixed with lavender, white, pink, and red blooms and foliage plants. Gladiola are must-haves for pollinator gardens and cut flower borders!

#ProPlantTips for Care:

Gladiolus bloom best in full sun and partial shade in a protected location. For especially windy sites and especially tall stems, some staking is recommended to keep your blooms from flopping. Plant your corms in well-drained, organically rich soil that has moderate, consistent moisture. Deadhead after the flowers fade and keep the leaves until they turn yellow. This way the corm stores food for next year. Then in fall, lift your bulbs out of the ground and store in a nylon stocking or brown paper bag in a cool, dry location with good ventilation above freezing. Each year you'll notice more and more little corms forming around the base of the parent corm for more blooms each year!

  • Full Sun & Partial Shade
  • Moderate Moisture Needs
  • Organic Well-Drained Soil
  • Deadhead After Blooms Fade & Prune or Dig in Fall
  • Deer & Rabbit Resistant

Rose Supreme Gladiolus is just the vertical pop of refreshing color your landscape has been craving! Fitting anywhere sunny, these perennial corms are versatile decorations indoors and out! Reserve yours at and get them shipped to your growing zone at the proper planting time for you today!
