What Is Ansellia Africana?
Ansellia africana commonly called Leopard Orchid or Trash Basket are popular orchids and feature leopard-like spotted flowers which gives them the common name, 'Leopard Orchids'.
The common name "Trash Basket" is in reference to their habit of creating a makeshift container (basket) of aerial roots to catch falling leaf litter for nutrients. This basket catches the decaying leaves and litter upon which the plant feeds.
Trash Basket Orchids have white, needle-like aerial roots which point upwards, taking the form of a basket around large, yellow, cane-like pseudobulbs. The orchid produces thick, cane-like pseudobulbs that store water and nutrients, topped with strap-shaped leaves.
In the wild, it experiences a distinct wet and dry season, which shapes its growth cycle and explains why it responds so well to seasonal changes in watering and feeding once brought indoors. Leopard Orchid requires very bright light and a dry rest of about 4-6 weeks to enhance blooming. They are very drought-tolerant but they perform better if kept evenly moist throughout the year.
Botanical name: Ansellia africana
Tribe: Cymbidiieae
Subtribe: Cymbidiinae
Common names: Leopard Orchid, Trash Basket
Origin: Ansellia africana are native to tropical and southern Africa. They are found alongside coasts and rivers in the canopy of trees. John Ansell, an English assistant botanist named Leopard Orchids in 1841 when he found the first plant in Fernando Po Island in West Africa. The genus name is abbreviated as Ansel or Aslla in horticultural journals.
How big does a Leopard Orchid get indoors? Leopard Orchids are large, perennial epiphytes in their native habitat where they are found sometimes in spectacular clumps attached to the branches of tall trees. Due to its size, Ansellia africana is best suited large spaces; the mature plants can become quite large, with pseudobulbs reaching 2 feet or more in height.
Flowers: Leopard Orchids pseudobulbs give rise to the tall flower-spikes about 2.5 feet tall with many (upto 100) delicately scented flowers. The flowers are short-lived, lasting about 10 days only but they are produced in abundance. Flower spikes emerge from the base of mature pseudobulbs in late winter to spring, with blooming lasting several weeks. Established plants often flower multiple times a year under the right growing conditions.
Medicinal Uses: Leopard Orchid is listed as an endangered species due to overexploitation and destruction of its natural habitats. The orchid has been shown to have some medicinal uses in the treatment of Alzheimer's disease.
Is Leopard Orchid toxic? No, Leopard Orchids are non-toxic to both humans and pets. They are safe for cats, dogs and other pets. You can comfortably grow these orchids in a home with children and pets.
Where to Buy: If you would like to add orchids to your collection, you may acquire these plants from Etsy (Link to Etsy).

How often should I water my Ansellia africana indoors?
Since Ansellia africana experiences a defined wet and dry season in nature, its indoor watering schedule should mimic those seasonal shifts.
For lush growth and regular blooms, water Leopard Orchid thoroughly in the growing period and allow the top half of soil to dry out between waterings. Keep the soil moderately moist but never soggy to avoid rotting.
Cut down on watering in the cold period (fall and winter) as growth is minimal at this time. Do not allow the soil to dry out completely as it can result in wrinkled pseudobulbs and drooping leaves.
Use lukewarm water as consistently watering with cold water will result in cold shock which can cause stunted growth. Only use chlorine-free water like rainwater to prevent black leaf tips. Avoid wetting the foliage to minimize fungal diseases.
Give Leopard Orchids a dry spell of about 4-6 weeks, every 6 months to promote blooming. In their natural habitat, they usually bloom at the end of a dry spell.
Take care not to overwater; Leopard Orchids are more tolerant of dry soil conditions than Lady Slippers Orchids (Paphiopedilum Orchids) due to the presence of the large pseudobulbs and thick leaves.
Light Requirements
Leopard Orchid thrives in very bright light with 6-8 hours of morning or late evening sunshine. Keep it away from hot midday sunshine to prevent scorching of the leaves.
If the natural lighting is not adequate, consider investing in a grow light to supplement it as too little light may result in weak growth and fewer blooms.
The normal leaf coloration of Leopard Orchid is yellowish-green. Dark-green leaves indicate that the orchid is not receiving enough light while yellow leaves indicate too much light.
Regularly rotate the pot to ensure that it gets adequate light on all sides for even growth and prevent unbalanced growth.
Temperature & Humidity
Ansellia africana flourishes in a warmth of 24-290C with cooler night temperatures of 15–180C; cool nights are essential to trigger flowering. Keep the orchids away from drafts to avoid sudden temperature changes as they can lead to bud blast, reduced growth, drooping and poor flowering.
High humidity of 60-75% is essential for Leopard Orchids to thrive. Low humidity may result in flowerbud drop, and brown leaf tips and esdges. To raise humidity, group the plants together, set the pot on a wet pebble tray or use a cool mist humidifier. Do not mist the leaves and maintain a good airflow to minimize fungal diseases infestations.
What is the best fertilizer schedule for Leopard orchid?
Feed Ansellia africana with a nitrogen-rich, water-soluble orchids fertilizer every two weeks during the growing season (spring and summer) for healthy growth. For strong blooms, switch to a high-phosphorus fertilizer as flowering begins. Do not feed an orchid that is in flower.
Stop feeding in the cold season (fall and winter) as growth is minimal. Therfore, feeding at this time may result in fertilizer burn and death of the orchid.
If Leopard Orchids are not receiving adequate nitrogen, they will start growing a trash basket with numerous non-absorbing roots growing upwards.
In feeding, it is better to err on the side of underfeeding than overfeeding as can result in the loss of roots and death of the orchid. It can also lead to vegetative growth instead of flower production.
Potting Medium
Ansellia africana's thick roots need excellent drainage and airflow, so a chunky, well-aerated medium works best. The best potting mix for Leopard Orchid should be a rich, loose, well-draining bark soil. A mix of 50% orchid bark, 30% charcoal (to improve aeration) and 20% perlite or sphagnum moss is ideal for this orchid.
Leopard Orchid can be mounted on a piece of cork or tree fern mount, similar to how it grows in the wild. A basket-style pot that allows maximum airflow around the roots is also a good option for this orchid.
Repotting
Leopard Orchids bloom best when they are pot-bound. Repot only when growth begins to suffer, shortly after blooming is over. Repot when the orchid has outgrown its pot and the new growth reaches out over the edge of the pot or when the soil has broken down completely.
Usually, repotting every 2-3 years is sufficient for this orchid. Use a pot with proper drainage holes or slits as the roots need good air circulation. The pot should be only 1 size larger than the current one. Check out these orchid pots on Amazon.
When repotting, shake off excess soil and trim off any dried and shrivelled pseudobulbs. Use a loose, free-draining bark soil.
Pruning & Grooming
Pruning Ansellia africana involves:
- Trimming the spent flower spikes after blooming to encourage new growth.
- Removal of dead and diseased leaves to keep the plant neat as well as discourage pest and disease infestations.
- Cut the leaves at the base with a sharp, clean knife or pair of pruning scissors.
- Make clean cuts and avoid injuring the orchid unnecessarily to avoid fungal diseases.
Occasionally clean the leaves by damp-wiping with a soft cloth to get rid of dust and minimize pests infestations.
How to encourage blooming in Ansellia Orchid?
Getting Ansellia africana to flower indoors comes down to replicating its natural seasonal rhythm:
- Light: Give the orchid bright indirect light with 6-8 hours of sunlight daily throughout the growing season; place it infront of a large, east- or south-facing window. If the natural lighting is not adequate, instal a grow light to increase it.
- Watering: Water when the top 2-3 inches of soil feel dry and do not allow the soil to dry out completely for a prolonged period. Significantly, cut down on watering in the cold season and give it a 4-6 weeks rest period.
- Soil & potting: Use a pot with proper drainage holes or slits and a chunky, loose, well-draining potting mix.
- Humidity: Set the pot on a wet pebble tray, use a cool mist humidifier or group the plants together to increase humidity.
- Temperature: Maintain a warmth of 24-290C with cooler night temperatures of 15–180C. Keep it away from sources of drafts like heat sources, open doors, drafty windows, hot air vents, AC units among others.
- Fertilizer: Feed the orchid every 2 weeks with an orchids fertilizer in spring and summer. Switch to a high-phosphorus bloom formula as flower spikes begin to form. Do not feed in fall and winter to prevent fertilizer burn.
Leopard Orchid Propagation
Leopard Orchid is best propagated at the beginning of the growing season once flowering is over by division of the rhizome.
How to propagate Leopard Orchid from rhizomes
- Carefully remove the orchid from its pot and find natural divisions where 3-4 healthy pseudobulbs are attached.
- With a clean knife or pruning scissors, gently split the rhizome into sections. Retain at least 3 shoots on each section.
- Seperate the roots attached to each division from the mother's root ball. Remove the old potting soil attached to the roots.
- Select a pot about 1-2 inches larger than the pseudobulb. Ensure the pot has enough drainage holes and slits to prevent rotting.
- Fill the pot with orchids potting mix and place each section in the center of the pot and bury the roots in the soil. Ensure that the bottom of the pseudobulb is level with the top of the soil.
- Water the soil lightly and stake each newly repotted plant to prevent it from toppling over.
- Place the set up in a warm, well-lit place and maintain the soil moist until the new orchids establish their own roots after which you can begin routine care.
