Overview of Pterygodium connivens Schelpe
Pterygodium connivens Schelpe is an orchid species that belongs to the Orchidaceae family and is native to South Africa. It is also known as the Rock Orchid or the Dance Fly Orchid due to its unique pollination strategy. This plant is not commonly found in cultivation and is mostly found growing in the natural habitats.
Appearance of Pterygodium connivens Schelpe
The plant has a slender stem of about 30 centimeters. The leaves are narrow and elongated, and the plant produces small, greenish-yellow flowers, arranged on an inflorescence that can reach up to 60 centimeters in height. The flowers are small and intricate, shaped like a tiny dancer with fluttering arms and legs, mimicking a female dance fly, which is the pollinating insect attracted to this orchid.
Pollination and Uses of Pterygodium connivens Schelpe
Pterygodium connivens Schelpe has a unique pollination strategy, whereby it employs deception to attract the Dance fly (Empis sp.), which is its primary pollinator. The plant releases a floral scent that mimics the scent of the female dance fly, which the male dance fly follows mistaking the flower as a potential mate. The male fly then attempts to mate with the flower, pollinating it in the process.
The plant itself is not known to have any medicinal or culinary uses. However, the plant has considerable value in the conservation of orchid species in South Africa, and efforts are being made to protect and preserve this threatened plant species.
Light requirements
Pterygodium connivens Schelpe, commonly known as the Rusty swamp orchid, prefers a bright environment with indirect sunlight. The plant can tolerate either partial sun exposure or complete shade, but it requires at least four hours of bright, indirect sunlight per day for optimal growth and flowering. If the plant receives too much direct sunlight, it may suffer sunburn or wilt.
Temperature requirements
Pterygodium connivens Schelpe thrives in mild to cool temperatures. The plant grows best in temperatures ranging from 10°C to 27°C (50°F to 81°F). High temperatures can cause the plant to wilt and dry out. However, the plant can survive in frosty conditions and when snow is present.
Soil requirements
Pterygodium connivens Schelpe has specific soil requirements for optimal growth. The plant prefers moist, well-draining soils with good water retention capacity. The soil should be slightly acidic to neutral, with a pH of about 6.0-7.0. The plant can grow in different soil types, including loamy soils, clay soils, and sandy soils, as long as they have good water retention capability. However, the plant is intolerant to flooding and standing water that may cause root rot and other fungal diseases.
Cultivation of Pterygodium connivens Schelpe
Pterygodium connivens Schelpe, commonly known as the Bonnet Orchid, is a terrestrial orchid species that is native to South Africa. This plant is suitable for cultivation both in pots and in the ground. The following are tips on how to cultivate Pterygodium connivens Schelpe successfully:
- Plant Pterygodium connivens Schelpe in well-drained soil with good aeration. A mixture of sand, peat moss, and perlite in a 1:1:1 ratio is ideal.
- The plant prefers bright, indirect light or partial shade, especially during the hottest part of the day.
- The ideal temperature range for this plant is 12°C to 25°C. It is best to keep the plant in a cool location, away from any drafts during the winter months.
Watering Needs of Pterygodium connivens Schelpe
Pterygodium connivens Schelpe requires regular watering to keep its soil moist. Here are some watering tips:
- Water the plant once a week during the growing period or when the top inch of soil feels dry to the touch.
- Avoid overwatering the plant, as this can lead to root rot.
- Consider using rainwater or distilled water for watering, as Pterygodium connivens Schelpe is sensitive to excessive salts in tap water.
Fertilization of Pterygodium connivens Schelpe
Fertilizing Pterygodium connivens Schelpe is important to ensure healthy growth and blooming. Here are some fertilization tips:
- Use a balanced, water-soluble fertilizer, diluted to half strength, every two weeks during the growing season.
- Avoid fertilizing during the winter months while the plant is dormant.
- Apply fertilizer to moist soil, as dry soil can result in fertilizer burn.
Pruning of Pterygodium connivens Schelpe
Pterygodium connivens Schelpe may require pruning to maintain its growth and appearance. Below are some pruning tips:
- Remove any dead, damaged, or yellowing leaves by cutting them off at the base of the plant.
- Remove the flower stalk after blooming, but be careful not to damage any developing buds or new growth.
- Trim any aerial roots that have become excessively long to prevent tripping hazards and to keep the plant tidy.
With proper care, Pterygodium connivens Schelpe can thrive and produce beautiful blooms for many years.
Propagation of Pterygodium connivens Schelpe
Pterygodium connivens Schelpe can be propagated by two primary methods:
Seed Propagation
Propagation through seed is the most common method for Pterygodium connivens Schelpe. Collect the seeds during the summer months, which is the time for natural seed fall. Clean the seeds from the capsule and dry them for at least a day. After drying, store the seeds in a cool and dry place until the planting season arrives. The planting season usually falls between autumn and winter, during which the available soil moisture will allow for the successful establishment of seedlings. For the best results, you should sow the seeds as soon as you get them instead of waiting for the planting season.
For planting, you should choose a well-draining and nutrient-rich soil mixture. Plant the seeds about 5 to 10mm deep in the soil, ensuring they are evenly spaced. Water the soil immediately after sowing and then monitor the soil moisture level regularly to ensure it remains moist but not waterlogged.
It takes approximately 2 to 3 months for the seeds to germinate. Once the seedlings reach 50mm in height, they can be transferred to their permanent growing location.
Division Propagation
Propagation through division is suitable for mature Pterygodium connivens Schelpe plants. Divide the plant when it is dormant, either in the fall or early spring.
To divide the plant, dig a hole around the base, and then carefully lift the plant out of the soil. Gently brush off the excess soil to expose the rhizomes. Use a sterilized knife to divide the rhizomes into several segments. Each segment should have at least one leaf and two or three healthy rhizomes.
After division, transplant the segments into a well-draining and nutrient-rich soil mixture. Water the soil immediately after planting and then monitor the soil moisture level regularly. You should not allow the soil to become waterlogged as it may cause the plant to rot.
Mature plants that have been divided will take a few years to reach maturity again.
