General Appearance
The Ornithopus perpusillus L. plant grows up to 60cm in height. It has an unbranched stem with fluffy hairs visible on it and grows upwards. The leaves of the plant are compound, consisting of three leaflets with small hairs on either side. The flowers of bird's-foot broomrape are usually purple or pink in color with a white or yellow center. The plant's fruit is a small, flattened pod containing four to five seeds. Overall, the plant's unique bird's-foot-shaped leaves make it easy to identify and distinguish from other plants.
Uses
Bird's-foot broomrape plant's ornamental appearance makes it a popular choice for gardens, borders, and rockeries. Its ability to fix nitrogen in the soil also makes it valuable for ground cover and crop rotation. Additionally, the plant's medicinal properties have been used to treat ailments such as coughs and respiratory infections. The flowers and seeds are also edible and can be used in salads or soups.
Common Names
The plant is commonly known as bird's-foot broomrape due to its bird's-foot-shaped leaves. Other common names for the plant include bird's-foot clover, bird's-foot trefoil broomrape, and Ornithopus sativus.
Light Requirements
Ornithopus perpusillus L. thrives in full sunlight to partial shade. However, it grows best under full sunlight. Therefore, it is advisable to plant it in open spaces or areas with minimal shading to encourage maximum growth.
Temperature Requirements
The plant grows well in moderate temperatures ranging between 15°C and 25°C. However, it can tolerate high temperatures of up to 30°C for short periods. When exposed to extremely low temperatures, the plant deteriorates, and may eventually succumb to frost damage.
Soil Requirements
Ornithopus perpusillus L. grows well in well-drained sandy or loamy soils. The soil should have a neutral pH and be rich in nutrients such as phosphorus and nitrogen, which favors the growth of the plant. Moreover, the plant is drought-resistant and can survive in semi-arid soils with low water content.
Cultivation Methods for Ornithopus Perpusillus L.
Ornithopus perpusillus L. thrives in well-draining soils with a neutral pH level. It requires a sunny location to grow and has excellent drought resistance, making it an ideal plant for xeriscaping. Seeds can be directly sown on the soil surface in early spring or late fall. The plants have a slow growth rate and will typically reach maturity in two to three years.
Watering Needs for Ornithopus Perpusillus L.
This plant is drought-tolerant, but during its growing season, it requires regular watering. It is essential to avoid overwatering the plant as it can lead to rotting of the roots. Once established, it can go for extended periods without water. If you're unsure whether to water your plant, check the soil's moisture level. Water the plant when the top inch of the soil is dry.
Fertilization of Ornithopus Perpusillus L.
Ornithopus perpusillus L. does not require heavy fertilization. You can feed it once a year in the early spring with a slow-release balanced fertilizer. Apply the fertilizer around the base of the plant to allow it to absorb essential nutrients. Avoid over-fertilizing as it can damage the plant.
Pruning of Ornithopus Perpusillus L.
You do not need to prune Ornithopus perpusillus L. as it grows naturally in a low-spreading mat. However, you can trim back any dead or damaged branches to maintain the plant shape. If it grows too tall, you can cut it back to control its height without affecting its health.
Propagation of Ornithopus perpusillus L.
Ornithopus perpusillus L., commonly known as Bird's-foot, is a low-growing herbaceous plant that is usually propagated by seed.
Seed Propagation
Seed propagation is the most common method of propagating Ornithopus perpusillus L. The seeds can be sown directly in the ground after the last frost date or started indoors six to eight weeks before the last frost date and transplanted outside once the plant has developed. It is essential to keep the seeds moist but not waterlogged during the germination period.
Ornithopus perpusillus L. is hard to transplant due to its taproot. As a result, starting seeds in biodegradable containers can avoid transplant shock.
Division
Ornithopus perpusillus L. is not usually propagated by division due to its taproot. However, mature plants can be carefully dug up, divided and transplanted.
Vegetative Propagation
Ornithopus perpusillus L. can be propagated vegetatively, but it is rare. Propagation can be achieved through stem cuttings or layering.
Stem cuttings should be collected in the late spring or early summer. They should be approximately 2-3 inches long and planted in well-draining soil. It is vital to keep the soil moist and humid for the initial few weeks until the plants establish roots.
Layering is a more efficient vegetative propagation method. To layer, choose a healthy and strong stem and gently scrape the green layer on the underside. Bend the stem and secure it into the ground with a wire staple. After roots have developed, cut and transplant the new plant.
Propagation of Ornithopus perpusillus L. can be challenging due to its taproot and low germination. However, seed propagation is the most effective method.
Disease Management
Ornithopus perpusillus L. is prone to some diseases which can affect its growth and yield. The common diseases that affect the plant include:
- Anthracnose: This is a fungal disease that affects the leaves, stems, and pods of the plant. It causes dark, sunken lesions, which eventually cause the affected parts to shrivel and die. To manage anthracnose, farmers should use fungicides and ensure proper drainage to prevent water from stagnating around the plant.
- Leaf Spot: Leaf spot is another fungal disease that causes the leaves to turn yellow and drop off prematurely. To manage this disease, farmers should remove the infected leaves and use a fungicide to prevent further spread.
- Rust: Rust is a fungal disease that appears as yellow-orange pustules on the leaves. It can spread quickly and cause the leaves to turn brown and fall off. To manage rust, farmers should use fungicides and prune infected areas.
Pest Management
Ornithopus perpusillus L. is also prone to some pests which can cause significant damage to the plant. The common pests that attack the plant include:
- Aphids: Aphids are small, soft-bodied insects that suck sap from the plant. They cause the leaves to curl and stunt the growth of the plant. To manage aphids, farmers should use insecticides or introduce natural predators, like ladybugs.
- Cutworms: Cutworms are caterpillars that feed on the plant's stem at night. They can cut the stem completely, causing the plant to die. To manage cutworms, farmers should use insecticides or apply diatomaceous earth around the plant.
- Thrips: Thrips are tiny insects that cause the leaves to turn silver or bronze. They suck sap from the plant and can cause significant damage if left untreated. To manage thrips, farmers should use insecticides or introduce natural predators, like mites or lacewings.
