Also called Swiss cheese vine, Adanson's monstera, Five-hole plant.
A climbing aroid from the rainforests of Central and South America and the Caribbean, smaller than the classic Monstera deliciosa. Its heart-shaped leaves are full of oval holes rather than deep splits. Indoors it climbs a moss pole or trails from a shelf, usually reaching 1 to 2.5 m.

Through the year
Let the top of the mix get almost dry, then water thoroughly and empty the saucer. Water less in winter. Rainwater or filtered water at room temperature is best in hard-water areas.
-
Spring
WeeklyRepot if roots fill the pot, start feeding and tie new stems to the pole.
-
Summer
WeeklyWater freely, keep the humidity up and watch for spider mites.
-
Autumn
Every 2 weeksStop feeding and let the mix dry a little more between waterings.
-
Winter
Every 2 weeksWater sparingly and keep it warm, away from cold drafts and heaters.
Feeding
Every 4 weeks in spring and summer. Balanced liquid fertilizer during the growing season. Do not feed in winter.
Care tips
-
Give it something to climb
On a moss pole it roots into the support and makes bigger leaves with more holes.
-
Keep it out of direct sun
Hot sun scorches the thin leaves; an east- or west-facing window works well.
-
Use an airy, slightly acidic mix
A blend of peat-free ericaceous compost and orchid bark drains fast and stops the roots rotting.
-
Root cuttings in water
Cut a piece with a node and an aerial root between spring and late summer and stand it in water until roots form.
-
Wear gloves when pruning
The sap can irritate skin and eyes.
Common problems
-
Root rot
What you seeLeaves yellow and droop while the mix stays soggy.
What to doRepot into an open, fast-draining mix and never leave the pot standing in water.
-
Spider mites
What you seeFine webbing and pale speckling on the leaves.
What to doRinse the leaves, raise the humidity and treat with insecticidal soap if they come back.
-
Brown, crispy edges
What you seeLeaf margins dry out and turn brown.
What to doThe air is too dry; group plants together or stand the pot on a tray of wet pebbles, away from radiators.
Pets
Is monstera adansonii safe for cats and dogs?
Not confirmed. Not on the ASPCA lists. The ASPCA lists its close relative Monstera deliciosa as toxic to cats and dogs because of insoluble calcium oxalate crystals, which irritate the mouth and cause drooling and vomiting; NC State notes the same crystals in this species.
Good to know
-
One explanation for the holes is that they let sunlight slip through to the lower leaves while the vine climbs.
-
In the wild its leaves can reach about 45 cm across, much bigger than on a houseplant.
-
Houseplants almost never flower; outdoors it produces a creamy white spathe in spring.
