Overview
Isolepis angelica B.L.Burtt, commonly known as Angelic isolepis, is a perennial herbaceous plant belonging to the family of Cyperaceae. It inhabits the shores of freshwater swamps, in the mountains and lowland areas of sub-tropical and tropical regions of the world, such as Australasia, Southeast Asia, the Pacific Islands, and eastern and southern Africa.
Appearance
The plant grows in clumps or tufts, forming dense cushions up to 30 cm in diameter. It has slender, smooth or slightly rough, green leaves that can grow up to 15 cm long and 1 mm wide. The inflorescence consists of small flowers, arranged in a dense, almost spherical cluster, about 3 to 6 cm in diameter, with greenish-yellow scales that encircle the flower spikelets. The flowers produce small, brownish-yellow seeds that are about 0.5 mm in diameter.
Common Names
In addition to Angelic isolepis, the plant is called Angelic flatsedge, Tangled soft rush, Isolepis grass, Conehead rush, Conehead club-rush, and Spiked club-rush, depending on the region and country.
Uses
Angelica Isolepis has several uses. In traditional medicine, the leaves are used to treat stomach upsets, fever, and diarrhea, while the roots are used for respiratory and chest problems. The plant is also used for weaving baskets, mats, and other handicrafts. Due to its ornamental value, Angelica isolepis is grown as an aquatic plant in ponds, water gardens, and containers, providing a charming green ground cover in moist areas. Lastly, the plant helps in soil retention, and erosion control along riverbanks, in ponds, and other wetland areas.
Light Requirements:
Isolepis angelica B.L.Burtt is a plant that thrives best in full sun to partial shade. A minimum of 4 hours of direct sunlight each day is required to avoid its stem from rotting. The more limited light requirements of this plant make it an excellent plant for indoor cultivation or locations with indirect light.
Temperature Requirements:
The temperature requirements for Isolepis angelica B.L.Burtt are not strict. This plant can handle a wide range of temperatures from cool to warm. The ideal temperature range for the Isolepis angelica B.L.Burtt plant is from 60°F to 80°F. Extreme temperature changes might cause harm ranging from stunting in growth to leaf drop.
Watering Requirements:
Isolepis angelica B.L.Burtt plant requires a consistent supply of moisture to survive. This species thrives in wet to damp soil. When kept in a container, it's essential to ensure that the soil is always moist but not overly saturated. The water's pH must be slightly acidic to neutral (5.5-7.5), and it would be wise to avoid chlorinated water when irrigating. Coastal environments that are slightly salty are ideal for their cultivation.
Soil Requirements:
Isolepis angelica B.L.Burtt grows well in well-draining soil in addition to the above light and water conditions. The use of peat and mixtures of pumice stones can significantly improve soil drainage. A mixture of regular potting soil and sand in a 2:1 ratio will provide an ideal growing medium. Avoid the use of fertilizer, as it may encourage excessive growth and soft, weak stems.
Cultivation
Isolepis angelica B.L.Burtt is a beautiful perennial that grows in wet areas. It prefers full to partial sun and soil that is moist and sandy. This plant is particularly suitable for wetlands where it grows vigorously. However, it can tolerate some dry spells once fully established. The species is not frost-hardy and should not be exposed to temperatures below -5°C.
Watering
Isolepis angelica B.L.Burtt thrives in wet soils, so it requires a regular water supply. It is vital to keep the soil constantly moist but not waterlogged. The plant should not be allowed to dry out completely, especially during the hottest parts of the year.
Fertilization
When it comes to fertilizing Isolepis angelica B.L.Burtt, less is more. Too much fertilizer can cause excessive growth, which makes it difficult for the plant to maintain its shape. Instead, use a slow-release or liquid fertilizer once or twice a year for optimal growth.
Pruning
This plant does not require much pruning. Deadheading spent blooms and removing any damaged foliage or stems is sufficient. However, if the plant becomes overgrown, you can prune it back to shape in early spring before new growth appears.
Propagation of Isolepis angelica B.L.Burtt
Isolepis angelica B.L.Burtt is a semi-evergreen to deciduous plant commonly known as Angel's hair or Fibre-optic plant. It is an attractive plant due to its fine, hair-like foliage that gives a unique texture in the garden. Propagation of Isolepis angelica B.L.Burtt is easy and can be done through several methods.
Propagation by Division
Division is the easiest and most common method for propagating Isolepis angelica B.L.Burtt. This method involves separating the mature plant into smaller sections, each consisting of roots and shoots, and replanting them in new pots or garden beds. This method should be done during early spring when the plant begins to grow actively.
The steps involved in propagating Isolepis angelica B.L.Burtt by division include lifting the plant carefully, removing any dead or damaged leaves, separating the root clumps by gently pulling them apart, and replanting each section in the new location.
Propagation by Seed
Propagation of Isolepis angelica B.L.Burtt can also be done by seed. However, it is a more time-consuming and challenging method compared to division. Seeds should be sown in early spring in trays or pots filled with a well-draining soil mix. After sowing, cover the seeds lightly with soil mix and water gently.
The trays or pots should be kept in a warm, humid location and kept moist with regular watering. Germination can occur within two to four weeks after sowing. Once the seedlings reach a reasonable size, they should be transplanted into their individual pots or garden beds.
Propagation by Cuttings
Propagation of Isolepis angelica B.L.Burtt can also be done through cuttings. However, this method requires some skill, and success rates can be low. Cuttings should be taken from healthy juvenile plants in spring or early summer when the plant is actively growing.
The stems should be cut with a sharp, clean cutting tool, and the leaves on the lower half should be removed. The cuttings should be dipped in hormone rooting powder and planted in pots filled with moist, well-draining soil mix. The pots should then be placed in a sheltered location and kept moist with regular watering.
Overall, Isolepis angelica B.L.Burtt is an attractive and easy-to-propagate plant, which can be propagated through division, seed, or cuttings.
