Introduction
Matricaria hirta (Thunb.) DC., also known as hairy or rough chamomile, is a medicinal plant native to Europe and Asia. It belongs to the family Asteraceae and is closely related to the chamomile plant, but with some distinctive differences in appearance and usage.
Description
The plant grows up to 60 cm in height and has hairy stems and leaves, hence the common name "hairy chamomile". Its leaves are finely divided and have a feathery appearance. The plant produces flowers that are yellow and disc-shaped and have a distinctive sweet smell. Unlike the chamomile plant, the flowers of Matricaria hirta only have a few rows of white, needle-like ray flowers that surround the yellow disk. The fruits of the plant are tiny, ribbed achenes that contain the small, black seeds.
Common Names
Besides "hairy" or "rough" chamomile, Matricaria hirta is also commonly known as wild chamomile, gueldres rose, and double chamomile.
Uses
The plant has been used traditionally for its therapeutic properties in Europe and Asia for centuries. It is known to have anti-inflammatory, antispasmodic, and sedative effects. The flowers and leaves of the plant are commonly used to make tea that is believed to have soothing properties and can help with digestive problems, menstrual cramps, and insomnia. The essential oil extracted from the plant has been used in aromatherapy for its calming and relaxing properties.
Matricaria hirta is also used in skincare products for its anti-inflammatory and antiseptic properties. It is believed to be effective for treating acne, eczema, and other skin irritations. The plant's extract is added to shampoos and hair products for its ability to soothe and condition the scalp.
Light Requirements
Matricaria hirta is a sun-loving plant that requires at least 6 hours of direct sunlight per day to thrive. It is recommended to plant the seeds in a location that receives full sun exposure throughout the day.
Temperature Requirements
Matricaria hirta is best grown in cool climates with temperatures ranging from 15 to 20 degrees Celsius. The plant can tolerate mild frost but is not adapted to survive in extremely cold temperatures. In warmer regions, the plant may require partial shade to avoid overheating.
Soil Requirements
The plant prefers well-drained soil with a pH range of 5.5 to 7.5. Sandy loam soil enriched with organic matter is ideal. The soil should be well-aerated to prevent waterlogging, which can lead to root rot. Additionally, the plant prefers a consistent supply of moisture but is susceptible to overwatering and soil saturation, which can harm the roots and ultimately affect the plant's growth and health.
Cultivation Methods
Matricaria hirta, also known as hairy chamomile, is a hardy annual plant that is easy to grow. It can be grown in a wide range of soil types, including sandy, loamy, and clay soils, as long as they are well-drained and fertile. The plant prefers full sun but can also tolerate partial shade. The seeds can be sown directly in the ground in the early spring, or in the fall for overwintering, or started indoors about six weeks before the last frost date. The plant grows quickly and can reach a height of up to two feet.Watering Needs
Matricaria hirta requires regular watering, especially during dry periods or in hot weather. The soil should be kept moist but not waterlogged, as excessive moisture can lead to root rot. It is advisable to water the plant deeply once a week rather than giving it frequent shallow watering. During the flowering stage, the plant may require more water to maintain the blooms.Fertilization
Matricaria hirta does not require heavy fertilization. A balanced fertilizer can be applied at the beginning of the growing season, followed by monthly applications of a light fertilizer until the plant reaches maturity. Over-fertilization can lead to lush foliage at the expense of flowers. Organic fertilizers such as compost, manure, or bone meal can also be used to improve soil fertility.Pruning
Matricaria hirta does not require regular pruning. Deadheading spent blooms can encourage the plant to produce more flowers. Pinching back the stems in the early stages of growth can also promote bushier growth and more flowers. For a more compact plant, the stem tips can be pinched back by one-third early in the growing season. However, excessive pruning can delay blooming, so it is important to exercise moderation.Propagation of Matricaria hirta (Thunb.) DC.
Matricaria hirta, commonly known as hairy or rough chamomile, is a perennial herbaceous plant that is native to Europe and Asia. It belongs to the family Asteraceae and is widely cultivated for its medicinal properties, ornamental value, and essential oil content. Propagation of Matricaria hirta is relatively easy and can be done through various methods such as seed sowing, division, and stem cuttings.
Seed Sowing
The easiest and most common way to propagate Matricaria hirta is through seed sowing. The seeds can be sown directly in the ground during spring or fall. For indoor propagation, sow the seeds in trays filled with seed-starting mix. Keep the soil moist and place the tray in a warm location with sufficient light. The seeds usually take around 10 to 15 days to germinate. Once the seedlings are big enough, they can be transplanted into individual pots or directly into the garden.
Division
Dividing established Matricaria hirta plants is another method of propagation. The plant can be divided in either fall or spring, depending on the climate and growing conditions. Dig up the plant and gently separate the root ball into smaller sections, ensuring each section has some roots attached. Replant the divisions immediately in well-drained soil, and water well.
Stem Cuttings
Propagation of Matricaria hirta can also be done through stem cuttings during the growing season. Take a stem cutting of around 4 to 6 inches with a few leaves attached. Dip the cut end in rooting hormone and plant it in a pot filled with potting soil. Keep the soil moist and place the pot in a warm, bright area. The cuttings usually root within 3 to 4 weeks and can be transplanted into individual pots or directly into the garden.
Propagation of Matricaria hirta is relatively easy and can be done with minimal effort. With the right growing conditions, the plants can grow and thrive, providing beautiful blooms during the growing season.
