Origin and Common Names
Commelina benghalensis L. var. hirsuta C.B.Clarke, commonly known as hairy dayflower, is a species of flowering plant belonging to the Commelinaceae family. This plant is native to tropical and subtropical regions of Asia and Africa and is found in many other parts of the world as an introduced species.
Appearance
Hairy dayflower is a small annual herb that grows up to 1.5 feet in height. It has green, angular stems that are often hairy and four-angled. The leaves are simple, alternate, and ovate in shape, measuring 2-4 inches in length. The plant produces small, blue or purple flowers with three petals that bloom from summer to fall. The fruit is a capsule containing small, black seeds.
Uses
Hairy dayflower has several traditional medicinal uses in many parts of the world, including India, China, and Nigeria. Various parts of the plant are used to treat a wide range of ailments such as fever, diarrhea, dysentery, and respiratory infections. Additionally, this plant has been used in traditional Chinese medicine to treat respiratory inflammation, asthma, and coughs.
However, hairy dayflower is not commonly used in Western herbal medicine due to the lack of clinical evidence supporting its effectiveness. The plant is also known to contain toxic compounds that can cause adverse health effects in humans and animals if consumed in large quantities.
Growth Conditions of Commelina benghalensis L. var. hirsuta C.B.Clarke
Commelina benghalensis L. var. hirsuta C.B.Clarke, commonly known as hairy Asiatic dayflower, is a low-growing annual herb that can thrive in various growth conditions, ranging from sunny to partially shaded areas.
Light Requirements
Hairy Asiatic dayflowers require ample amount of sunlight to grow well, although they can also thrive in partially shaded areas. They prefer environments with moderate to bright light, but can survive in low light conditions as well.
Temperature Requirements
These plants prefer warm and humid environments with temperatures ranging between 20 to 30°C (68 to 86°F). They cannot withstand extreme cold weather, and frost can kill the plant.
Soil Requirements
The soil for growing hairy Asiatic dayflowers should be well-draining and fertile. They prefer moist soils with good organic matter, as it facilitates seed germination and promotes healthy growth. Sandy loam soils with a pH range of 5.5 to 7.5 are best suited for this plant.
Hairy Asiatic dayflowers are versatile plants and can adapt to different soil types, although they prefer ones with good drainage and nutrients.
Cultivation Methods
Commelina benghalensis L. var. hirsuta C.B.Clarke is a tropical perennial plant that thrives in warm and humid climates. It prefers well-drained soils with high organic matter content and requires partial to full sunlight. The plant can be propagated from seeds or stem cuttings and typically grows up to 50 cm in height.
As a relatively low maintenance plant, Commelina benghalensis L. var. hirsuta C.B.Clarke can be easily grown in pots or in the ground. It can also be used as a ground cover or in mixed borders with other plants. To ensure optimal growth conditions, provide adequate space for the plant to spread and grow.
Watering Needs
Commelina benghalensis L. var. hirsuta C.B.Clarke requires regular watering to keep the soil consistently moist. However, be careful not to overwater the plant, as standing water can cause root rot. Water the plant deeply and thoroughly, making sure the soil is completely saturated but not waterlogged. During dry spells or hot weather, increase the frequency of watering.
Fertilization
Commelina benghalensis L. var. hirsuta C.B.Clarke benefits from regular fertilization to promote healthy growth and flowering. Use a balanced, all-purpose fertilizer every two to three weeks, or as instructed on the label. When applying fertilizer, be careful not to over-fertilize, as this can lead to excessive vegetative growth and reduced flowering.
Pruning
Regular pruning can help promote a fuller, more bushy appearance in Commelina benghalensis L. var. hirsuta C.B.Clarke. Pinch back the tips of the stems or prune back the entire plant by a third to control the plant's height and spread. Pruning also encourages the plant to produce more flowers by directing its energy towards the development of blooms. Prune the plant in the early spring before the new growth emerges.
Propagation of Commelina benghalensis L. var. hirsuta C.B.Clarke
Commelina benghalensis L. var. hirsuta C.B.Clarke, commonly known as hairy wandering jew, is a perennial herb with a succulent stem, belonging to the Commelinaceae family. It is native to tropical and subtropical regions of Asia and Africa and is known for its medicinal and ornamental properties. The plant can be propagated through various methods.
Propagation Methods
1. Seed Propagation: Commelina benghalensis var. hirsuta can be propagated by seeds that are obtained from mature fruits. The seeds are sown in a mixture of well-drained soil and compost. The soil should be kept moist, and the seeds should be kept in a warm and humid environment. Germination occurs within 2-3 weeks, and seedlings can be transplanted to their permanent location when they are large enough.
2. Root Division: Commelina benghalensis var. hirsuta can be propagated by dividing the roots of an established plant. The roots should be carefully dug up, and the plant should be divided into smaller sections with a sharp and sterile knife. Each section should have a healthy root and shoot. The sections can then be potted in a mixture of well-drained soil and compost and kept moist.
3. Stem Cuttings: Commelina benghalensis var. hirsuta can also be propagated by stem cuttings. Cuttings should be taken from the plant's healthy and mature stems. The cutting should be about 5-6 inches long, with at least one node. The lower leaves should be removed, and the cutting should be dipped in rooting hormone powder. The cutting can then be planted in a mixture of well-drained soil and compost and kept in a humid environment until roots develop.
4. Tissue Culture: Commelina benghalensis var. hirsuta can also be propagated through tissue culture techniques. This method involves taking small tissue samples from the plant and growing them in a sterile culture medium that contains nutrients, hormones, and growth regulators. The resulting plantlets can then be transplanted to soil and grown to maturity.
Disease and Pest Management for Commelina benghalensis L. var. hirsuta C.B.Clarke
Commelina benghalensis L. var. hirsuta C.B.Clarke, also known as hairy dayflower, is a weedy plant that generally experiences few disease and pest problems when grown under favorable growing conditions.
