Common Names
The common names for Eulophia pulchra include tiger orchid, beehive orchid, snake orchid, and spider orchid. The name "tiger orchid" comes from the plant's tiger-striped petals, while the name "beehive orchid" refers to the honeycomb-like structure of the plant's pseudobulbs. The name "snake orchid" and "spider orchid" comes from the long and slender shape of the plant's inflorescence.
Appearance

The inflorescence is a long and slender spike that can produce up to 100 blooms. The flowers are about 4 cm in diameter with yellowish-green sepals and petals, and a lip that is striped with yellow and brown.
Uses
Eulophia pulchra has a history of traditional medicinal use in the Mascarene Islands. The plant's tuberous roots contain several chemical compounds that are believed to have anti-inflammatory, analgesic, and antioxidant properties. In traditional medicine, the roots are used to treat various illnesses such as respiratory infections, arthritis, and indigestion. Additionally, the plant is also used as an ornamental plant for its beautiful flowers and foliage.
Light Requirements
Eulophia pulchra (Thouars) Lindl. thrives under partially shaded conditions. It is not adapted to intense sunlight and requires shade to avoid stressing the leaves. Too much sun exposure can also lead to leaf scorching and drying.
Temperature Requirements
Eulophia pulchra (Thouars) Lindl. prefers a warm and humid climate. It can tolerate temperatures between 20°C and 35°C. However, it cannot tolerate frost or extreme temperature swings. In colder regions, it is recommended to grow it indoors or in a greenhouse to provide enough warmth.
Soil Requirements
Eulophia pulchra (Thouars) Lindl. does well in well-drained soil, that is rich in organic matter and nutrients such as nitrogen, phosphorus, and potassium. It can tolerate slightly acidic to slightly alkaline soil conditions. However, it is essential to prevent the soil from drying out, as it prefers moist soil conditions.
Adding mulch or compost can improve soil fertility and moisture retention capabilities. It is also recommended to use a soil mix that contains peat moss, perlite, and vermiculite to improve soil texture and drainage.
Cultivation methods
Eulophia pulchra (Thouars) Lindl., commonly known as the African ground orchid, is an epiphytic plant that can grow up to two meters tall. It grows in warm climates, and the ideal temperature range for growth is between 15°C and 27°C. The plant requires well-drained soil, and it should be placed in a spot with partial or filtered sunlight. It can be propagated through division of its pseudobulbs.
Watering needs
When watering the African ground orchid, it is essential to ensure that the soil is moist, but not waterlogged. Overwatering can lead to root rot and damage the plant. The frequency of watering will vary depending on the climate and the size of the plant. It is recommended to water the plant once a week, but this may need to be adjusted in dry or humid weather conditions.
Fertilization
Eulophia pulchra (Thouars) Lindl. requires regular fertilization to promote growth and flowering. Use a balanced fertilizer that contains equal amounts of nitrogen, phosphorus, and potassium. This should be applied every two weeks throughout the growing season. However, it is important to discontinue the use of fertilizers during the dormant season.
Pruning
During the growing season, the African ground orchid may require pruning to maintain its shape and size. Pruning involves cutting back any dead or damaged leaves, as well as the spikes that have finished flowering. This should be done with a sharp and sterile pair of scissors or pruning shears to avoid introducing any infections to the plant. Pruning should be done once the flowering spikes have dried out.
Propagation of Eulophia pulchra (Thouars) Lindl.
Eulophia pulchra (Thouars) Lindl., also known as the beautiful Eulophia, is a species of terrestrial orchid that is native to Africa. It is a stunning plant with large, showy flowers that are often used in floral arrangements. Propagation of this species can be done through a few different methods.
Propagation by Seed
The most common method of propagating Eulophia pulchra is through seed propagation. Collect ripe seed capsules from the plant and allow them to dry out completely. Once the capsules are dry, remove the seeds and plant them in a well-draining mix of seed-starting soil and perlite. Keep the soil moist and warm, and the seeds should germinate in a couple of weeks.
Division
Eulophia pulchra can also be propagated through division. When the plant becomes too large for its pot, carefully remove it from the container and separate the individual pseudobulbs. Each pseudobulb should be planted in its own pot with fresh orchid mix and kept moist until new growth appears.
Tissue Culture
Tissue culture is another method of propagating Eulophia pulchra. This method involves taking a small piece of the plant's tissue and growing it in a sterile environment. Tissue culture is a great option for mass propagation of plants and is often used by commercial nurseries.
Conclusion
Propagation of Eulophia pulchra can be done through seed, division, or tissue culture. Each method has its advantages and disadvantages, so it's up to the grower to decide which one is best for their needs.
Disease and Pest Management for Eulophia pulchra (Thouars) Lindl.
Eulophia pulchra is a prized orchid, highly sought after for its beauty and fragrance. Like all plants, it is vulnerable to diseases and pests. Here are some of the most common ones to watch out for, and some strategies for dealing with them.
Diseases
One of the most frequent problems that Eulophia pulchra faces is fungal infection. This typically shows up as black spots on the leaves. These spots can quickly spread and cause the leaves to turn yellow, wilt, and eventually die. The best way to prevent fungal disease is to keep the plant properly ventilated, avoid overwatering, and take care to keep the foliage dry. Fungicides can also be used as a preventive measure before any sign of infestation.
Another common disease that can affect Eulophia pulchra is bacterial infection. This can cause leaf spots, stem rot, and wilting of the leaves and is most often caused by waterlogging and high humidity conditions. Sanitation and removal of infected parts are crucial steps in managing the disease. Bactericides can also be used to control the spread of the bacteria.
Pests
Eulophia pulchra can also fall prey to various pests, such as mealybugs, scale insects, and spider mites. These pests can attack the leaves, flowers, and stems of the plant and ultimately cause reduced plant vigor and damage to the blooms. The use of contact and systemic insecticides and miticides is often necessary to eliminate infestations.
Another potential pest problem is snails and slugs, which can munch away at leaves, flowers, and roots. To deal with these pests, handpicking, and use of bait are effective measures. In addition, it’s essential to keep the plant free of debris and soil clumps that can provide hiding places for these pests.
To keep Eulophia pulchra healthy, monitor it frequently for any signs of diseases or pests. When caught early, these issues can often be easily managed and controlled, ensuring that your orchid remains healthy and lovely for years to come.
