Hesperantha coccinea

Also Known As - river lily
Crimson Flag (Hesperantha coccinea) is a herbaceous, perennial plant native to South Africa. It is known for its large, deep red flowers that have a star-shaped appearance. The foliage is a glossy green contrasted with the bold red of the blooms. It grows in mounds reaching up to 0.3 meters high and blooms in late summer to winter. The plant is best grown in partial shade in well-drained soil. Its long-lasting blooms add a vibrant splash of colour to any garden and attracts hummingbirds and other pollinators. Crimson Flag is a tough, easy-to-grow plant for gardeners in temperate to mild climates.

watering

Watering for Crimson Flag plants should be done regularly but lightly. Water when the soil is beginning to dry out which should be every other day or every third day in hot weather. Water until it runs out of the drainage holes. When the weather is cooler, the frequency should be less. Over-watering can cause root rot, so it is important to not water too frequently. It is best to water your Crimson Flag in the morning so that the foliage has time to dry before nighttime.

sunlight

Crimson flag (Hesperantha coccinea) grows best in full sun, but will also tolerate partial shade. During the warmer months, this plant prefers full sun for most of the daylight hours. As temperatures cool down, the plant should maintain 4 to 6 hours of direct sunlight each day. In the winter months, Crimson Flag plants should remain in mostly bright, indirect light. When exposed to too much shade or sun, the blooming period will be reduced and the plant’s foliage will become leggy, resulting in fewer or smaller flowers.

pruning

Crimson flag (Hesperantha coccinea) should be pruned twice a year, in the early spring and late fall. In the early spring, snip off any dead stems and prune back the longest stems, leaving at least 2 or more developing buds at the base of the stem. In the late fall, after flowering has finished, remove any dead or weak stems and lightly prune the remaining stems to shape the plant. It's important to remember not to prune too vigorously as this may reduce flowering, and try to leave some of the old stems when pruning, as these will produce flowers the following season.
