Acidanthera (Gladiolus callianthus) Bulbs

Acidanthera Gladiolus callianthus is a beautiful bulbous perennial flower. It produces star-shaped white flowers with delicate purple centres, which appear in abundance during the summer months. The sword-like foliage of this plant provides an attractive backdrop to its showy blooms.

Acidanthera grows best in full sun and well-draining soil and prefers warm climates. Although it will survive light frost, it is not cold hardy enough to withstand severe winter temperatures.

This plant requires minimal maintenance and can be divided every two or three years for propagation purposes. With its easy care requirements and fragrant blooms, Acidanthera Gladiolus callianthus makes an excellent addition to any garden setting.

Acidanthera requires regular watering during the growing season. Water the soil until it is evenly moist but not soggy, making sure to avoid overwatering. The soil should be allowed to dry slightly between waterings.

Fertilize every two weeks with a balanced fertilizer and prune back faded blooms as needed for continuous flowering. When the leaves of Acidanthera begin to die back in late summer, stop watering and allow them to go dormant until spring when new growth will emerge again.

During colder months, provide winter protection from extreme cold temperatures by mulching around the base of plants or providing some other form of insulation such as burlap or straw.

Deadheading spent flowers encourages additional bloom throughout the growing season. With proper care, Acidanthera will produce an abundance of stunningly beautiful blooms year after year.
