Overview
Coeloglossum viride (L.) Hartman ssp. bracteatum (Muhl. ex Willd.) Hultén is a species of orchid native to North America.
Origin
Coeloglossum viride (L.) Hartman ssp. bracteatum (Muhl. ex Willd.) Hultén is native to North America, and can be found in Alaska, Canada, the United States, and Mexico. It typically grows in damp, open habitats such as swamps, bogs, and wet meadows.
Common Names
Coeloglossum viride (L.) Hartman ssp. bracteatum (Muhl. ex Willd.) Hultén is commonly known as the lesser round-leaved orchid or the frog orchid. The latter name references the plant's greenish-yellow flowers, which resemble the skin of a frog.
Uses
Coeloglossum viride (L.) Hartman ssp. bracteatum (Muhl. ex Willd.) Hultén is not typically used for medicinal or culinary purposes, as it is not a common plant and is not well-studied in these areas. However, because of its unique appearance, it is often grown as an ornamental plant in gardens and other outdoor spaces.
Appearance
Coeloglossum viride (L.) Hartman ssp. bracteatum (Muhl. ex Willd.) Hultén is a small, perennial plant that typically grows to between 10 and 30 cm in height. It has a single stem with two oval-shaped leaves at its base, which are between 2 and 6 cm long. The plant's flowers, which bloom from May to August, are greenish-yellow and have a distinctive lip that is heavily veined. The lip of the flower is designed to attract insects, particularly flies, which are lured in by the scent of the plant and help to pollinate it.
Light Requirements
Coeloglossum viride ssp. bracteatum is a shade-loving plant that thrives in low light conditions. These plants are often found growing beneath the canopy of trees or in areas that receive partial sunlight, such as the edges of forests or clearings. Exposure to direct sunlight can lead to leaf scorching and can inhibit the growth of these plants.
Temperature Requirements
Coeloglossum viride ssp. bracteatum grows well in cool environments with temperatures ranging from 50-70°F (10-21°C). These plants are known to grow in higher elevations and are tolerant of freezing temperatures. However, they cannot tolerate extreme heat and may suffer from heat stress if exposed to temperatures above 80°F (27°C).
Soil Requirements
Coeloglossum viride ssp. bracteatum prefer well-draining soils that are typically found in rocky or sandy areas. These plants have adapted to grow in nutrient-poor soil and do not require the addition of extra fertilizer. The soil pH should be neutral to slightly acidic, with a range of 6.0-7.5. Overwatering should be avoided, as these plants are susceptible to root rot in wet soil.
Cultivation
Coeloglossum viride ssp. bracteatum is a terrestrial orchid that can be found in woodlands, meadows, and rocky slopes. When cultivating this plant, it is essential to mimic its natural habitat to ensure optimal growth and development. Choose a spot that gets partial shade and has well-draining soil with a pH between 6.0 and 7.5.
Before planting, prepare the soil by loosening it and incorporating organic matter like leaf mold or compost. You can then plant the Coeloglossum viride ssp. bracteatum bulbs at a depth of about two inches. These bulbs prefer to be left undisturbed, so avoid transplanting them.
Watering Needs
Coeloglossum viride ssp. bracteatum requires consistent moisture, but it is crucial not to overwater. During the growing season, water regularly, ensuring that the soil remains moist but not waterlogged. Water less in the winter, reducing the frequency to prevent the roots from sitting in water.
If you are in a dry area, or your plants are in a particularly sunny location, you may need to water more frequently or use a mulch layer to help the soil retain moisture.
Fertilization
Coeloglossum viride ssp. bracteatum does not require fertilizer to thrive. These plants grow in nutrient-poor environments, and over-fertilizing can lead to damage to the delicate roots.
Suppose you want to fertilize your Coeloglossum viride ssp. bracteatum plants. In that case, it is best to use a slow-release, balanced fertilizer composed of equal parts nitrogen, phosphorus, and potassium in a ratio of 10-10-10. Apply only once during the growing season, after new growth emerges.
Pruning
Coeloglossum viride ssp. bracteatum does not require much pruning unless you want to use it for propagation. When the plants go dormant in the winter, you can gently lift and divide the bulbs to create new plants. This strategy can help prevent overcrowding and maintain plant health.
Propagation Methods for Coeloglossum viride (L.) Hartman ssp. bracteatum (Muhl. ex Willd.) Hultén
Coeloglossum viride (L.) Hartman ssp. bracteatum (Muhl. ex Willd.) Hultén can be propagated through a variety of methods. The most common methods include seed propagation, division, and tissue culture.
Seed Propagation:
The easiest method of propagating Coeloglossum viride (L.) Hartman ssp. bracteatum (Muhl. ex Willd.) Hultén is through seed propagation. The seeds should be sown in the fall or early spring in a well-drained soil mix. The seeds should not be covered, as they require light for germination. Germination usually occurs within 2-4 weeks.
Division:
Coeloglossum viride (L.) Hartman ssp. bracteatum (Muhl. ex Willd.) Hultén can also be propagated through division. The best time for division is in the fall when the plant is dormant. To propagate through division, carefully lift the plant out of the ground and gently separate the clumps. Each clump should have several bulbs and roots. Replant the new divisions in a well-drained soil mix.
Tissue Culture:
Tissue culture is a less common method of propagating Coeloglossum viride (L.) Hartman ssp. bracteatum (Muhl. ex Willd.) Hultén. However, it can be an effective method for propagating large quantities of plants quickly. Tissue culture involves taking a small piece of plant tissue and placing it in a sterile nutrient-rich medium. The tissue eventually grows into a new plant, which can then be transferred to soil.
Disease and Pest Management for Coeloglossum viride (L.) Hartman ssp. bracteatum (Muhl. ex Willd.) Hultén
