About Lion's Angraecum
Angraecum leonis · also called Lion's Angraecum, Lion Orchid · tropical
A compact monopodial orchid from Comoros and Madagascar bearing scimitar-shaped fleshy leaves and large, pure-white night-fragrant flowers with long nectary spurs. Grow warm with bright filtered light, high humidity, and a wet-dry watering cycle. Mounted or in small pots with very open bark mix; slow to establish but rewarding once specimen-sized.
Preferred mix: Coarse bark or mounted cork/tree-fern
Watch for — Root rot: Caused by overly retentive media or insufficient airflow. Roots turn brown and mushy. Switch to a more open bark mix, improve ventilation, and water only when the medium nearly dries.
Why lion's angraecum needs this mix
Lion's Angraecum is an easy-going houseplant — it just wants a free-draining general mix that holds some moisture but never stays soggy.
- Lion's Angraecum is adaptable, but like most houseplants it still needs air at the roots — a mix that drains freely while holding a working moisture reserve.
- A little perlite or bark stops ordinary compost compacting into an airless block over time, which is the slow, common cause of decline.
- It is not fussy about pH or special ingredients; getting the air-to-moisture balance right is what matters.
For the full picture on what makes up a good mix, see our guide to the main types of soil and potting media — it explains why each ingredient above behaves the way it does.
What goes wrong with the wrong mix
The wrong soil is one of the most common reasons lion's angraecum struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- Plain garden soil or a cheap, claggy compost compacts in the pot and slowly suffocates lion's angraecum's roots.
- A pure peat mix that dries to a hard, water-repelling block is hard to re-wet and stresses the plant.
- No drainage hole turns even a good mix into a stagnant, root-rotting sump.
Reusing tired, compacted old compost or skipping the perlite. A free-draining mix in a pot with a hole solves most "why is it struggling" cases for lion's angraecum.
pH — does it matter for lion's angraecum?
Lion's Angraecum is not fussy about pH — a slightly acidic to neutral mix (around pH 6.0-7.0), which a standard peat-free compost provides, is perfectly fine. No testing needed.
If you want to check or adjust it, the soil pH guide walks through testing and the safe ways to nudge a mix more acidic or more alkaline.
DIY mix vs a bagged one
A decent bagged houseplant compost works for lion's angraecum as long as you mix in perlite for air. The simple DIY ratio above is cheap and more reliable than a budget bag alone.
Drainage and the pot
A pot with a drainage hole and a saucer you empty after watering is all lion's angraecum needs — the free-draining mix does the rest.
Refresh lion's angraecum's mix every 18-24 months; even good compost slumps and compacts, and fresh, airy mix is often the simplest fix for a tired plant. When the time comes, our repotting guide for lion's angraecum covers the timing and technique step by step.
