About Lion's Angraecum
Angraecum leonis · also called Lion Orchid, Comet Orchid relative · tropical
Angraecum leonis is a compact Malagasy epiphytic orchid that produces large, waxy white flowers with a long nectar spur, pollinated by sphinx moths. Despite its modest size, it bears disproportionately large blooms with a sweet nocturnal scent. Prefers bright light and a cool dry winter rest. As an orchid, it is pet-safe.
Ideal humidity: 50-70%
Watch for — Root rot from winter over-watering: Continuing summer watering frequency in winter quickly kills roots. Reduce dramatically once temperatures drop.
The watering schedule, season by season
Lion's Angraecum grows on bark, not in soil — it wants its roots soaked then fully dried and exposed to air, never kept damp like a potted plant. The base rhythm for lion's angraecum is when roots are silvery and the medium approaches dryness, roughly every 7-10 days in summer, but the real interval moves with the season, the light and the pot — so treat the figures below as a starting point and always confirm with the plant itself.
- Spring & summer (active growth): Spring and summer: soak or dunk the roots/mount thoroughly about once a week, then let them dry almost completely before the next soak.
- Autumn (slowing down): Autumn: lengthen the gap between soaks as light and growth taper off.
- Winter (rest / dormancy): Winter: soak far less often — roughly every 2-3 weeks — and always let the roots dry fully in between.
Water thoroughly during the growing season. Provide a distinct drier rest from late autumn through winter, reducing watering to every 2-3 weeks. This dry-cool rest is critical for flower initiation.

How to tell lion's angraecum needs water
A calendar is the worst way to water lion's angraecum. Check the plant and the soil instead — for this species, look for these signals in order:
- Roots turn silvery-grey or chalky instead of green/plump.
- The mount or bark medium is bone dry and light.
- Leaves or pseudobulbs look slightly wrinkled or less rigid.
The most reliable single check is the first one on that list. When two signals agree, water; when they disagree, wait a day and look again — under-watering lion's angraecum for a day is almost always safer than over-watering it.
Overwatering vs underwatering lion's angraecum
The two failure modes can look alike at a glance, so check the soil weight and wetness before you decide. For lion's angraecum specifically:
Signs you are overwatering
- Mushy, brown, hollow roots that have stayed wet too long.
- Yellowing, soft leaves at the base.
- A persistently wet, never-drying medium.
Signs you are underwatering
- Leaves go limp, leathery or accordion-pleated; roots stay grey for long stretches.
- Shrivelling pseudobulbs or curling leaves.
Treating lion's angraecum like a normal houseplant — watering little and often into bark or moss that never dries — suffocates and rots the roots. Soak hard, then let it dry out.
Water quality notes
Rainwater or filtered water is best for lion's angraecum; many epiphytes are sensitive to softened water and tap-water minerals.
Seasonal and environmental adjusters
Every figure above shifts with the conditions in your home. For lion's angraecum, the levers that matter most are:
- Air movement matters as much as water — roots must dry between soaks to avoid rot.
- A bark or mounted medium dries far faster than moss, so the wetter the medium, the longer you wait.
- In high humidity you can soak less often; in dry heated rooms, more often but still let it dry.
Pot choice is part of this too — work out the right size with the pot size calculator, since a pot that is too big stays wet long enough to rot the roots of lion's angraecum.
Lion's Angraecum watering — frequently asked questions
How often should I water lion's angraecum?
Water lion's angraecum when roots are silvery and the medium approaches dryness, roughly every 7-10 days in summer. Spring and summer: soak or dunk the roots/mount thoroughly about once a week, then let them dry almost completely before the next soak. Winter: soak far less often — roughly every 2-3 weeks — and always let the roots dry fully in between.
How do I know when lion's angraecum needs water?
Roots turn silvery-grey or chalky instead of green/plump. The mount or bark medium is bone dry and light. Leaves or pseudobulbs look slightly wrinkled or less rigid. The single most reliable test for lion's angraecum is the first signal on that list — checking the soil or the plant directly always beats watering by the calendar.
What does an overwatered lion's angraecum look like?
Mushy, brown, hollow roots that have stayed wet too long. Yellowing, soft leaves at the base. A persistently wet, never-drying medium. Treating lion's angraecum like a normal houseplant — watering little and often into bark or moss that never dries — suffocates and rots the roots. Soak hard, then let it dry out.
What are the signs of an underwatered lion's angraecum?
Leaves go limp, leathery or accordion-pleated; roots stay grey for long stretches. Shrivelling pseudobulbs or curling leaves.
Can I use tap water on lion's angraecum?
Rainwater or filtered water is best for lion's angraecum; many epiphytes are sensitive to softened water and tap-water minerals.
