About Gladiolus Callianthus Murielae

Gladiolus Callianthus Murielae is a true summer garden showstopper. With a graceful, airy look, the white, star-shaped blossoms, each adorned with a striking purple heart, resemble miniature orchids. Enveloped by neat sword-like foliage, the cluster of flowers bloom one at a time along arching stems similar to its cousin the Gladiolus. No wonder it's a Royal Horticultural Society Award of Garden Merit winner.

Easy to grow, these blooms exude a sweet jasmine-like fragrance that reaches its peak in the evening, lending an enchanting touch to moonlit gardens. With a slender form they truly shine when grouped in clusters of five or more, or when artfully scattered amid borders or meadows beckoning butterflies and an array of other pollinators from August to the first frost.

This plant is also known as: Acidanthera, Abyssinian Gladiolus, Fragrant Gladiolus, Sword Lily and Peacock Orchid.

How to Grow Acidanthera

Planting Acidanthera

  • Plant in spring after the last frost.
  • If you cannot plant your bulbs and perennials right away, store them in a cool, dry, dark location, like a basement.
  • Plant them with the pointy end up in a sunny to semi-shaded area about 13 cm (5 in) deep and 13 to 15 cm (5 to 6 in) apart.
  • Water thoroughly after planting.

Growing Acidanthera

  • Plant in groups which then appear more natural.
  • These bulbs do best in well-drained soil.
  • The advantage of acidanthera is that it blooms after the other summer-flowering bulbs.

Acidanthera Care

  • When in bloom, feel free to cut some flowers for bouquets.
  • Flowers are pleasantly fragrant, so plant them where their fragrance can be appreciated.

Winterizing Acidanthera

  • After flowering, the leaves should be allowed to die down. The leaves will gather sunlight and provide nourishment for next year’s show.
  • You should be able to grow them right up into a USDA zone 4 with no problem outdoors. This is a cold-hardy bulb that does not require any winter protection in colder gardens.
