Overview
Every leaf explains the common name. Bold green strokes radiate from the midrib across a paler field, backed by deep purple-red beneath, so the markings mimic the eye of a peacock feather. The plant sits in the prayer plant family, the Marantaceae, and its origins lie on the rainforest floor of eastern Brazil.
It moves, as its relatives do. Each leaf rises and folds in the evening, then reopens at dawn, a behavior called nyctinasty that lends the plant a daily rhythm. Its rainforest origin dictates how you grow it as well: warm air, consistent soil moisture, and humidity on a level with the air beneath a forest canopy.
All of that puts it beyond a beginner. The plant is demanding about water quality and dry air, and it registers a lapse in either as brown leaf margins almost at once. Meet its conditions, however, and little else indoors rivals the patterning it carries.
Care
The short version: bright indirect light, never direct sun, with soft water that keeps the soil moist but never soggy, warmth in the 65°F to 75°F (18°C to 24°C) range, and humidity at 60% or higher.
Light
Position the plant in bright, indirect light, the brightness you get a few feet back from a window rather than pressed against the glass. Part shade and even full shade are tolerated, but direct sun burns the leaves and bleaches away the very pattern it is grown for.
Water
Keep the soil moist but never waterlogged across spring and summer, then taper off from fall into late winter. Reach for distilled or rain water, since the fluoride carried in tap water accumulates in the leaf and browns the margins. Excess water is the quickest route to rotted roots.
Soil
Set it in a well-drained, humusy mix built on organic matter, with perlite folded in to keep the structure open and airy. Hold the pH on the acidic side of 8.0, and confirm the pot drains freely so the roots are never left standing in water.
Temperature
Keep the room between 65°F and 75°F (18°C to 24°C). As a tropical plant it has no cold tolerance, so position it well away from chilly windows and the draft off air vents.
Humidity
Humidity trips most growers up. The plant calls for 60% or higher, and dry indoor air announces itself quickly as crisp brown margins, so a humidifier or pebble tray generally pays off.
Feeding
Apply a balanced fertilizer monthly through the growing season, spring into summer. Halt it altogether in winter, when growth stalls and added nutrients serve no purpose.
Pruning
Pruning needs are minimal. Cut away any damaged or browned leaves as they show, and wipe the broad leaves occasionally with a damp cloth so a film of dust does not dull them or cut into the light they catch.
Repotting
Schedule a division and repotting roughly every two years, in late spring. The job renews the mix and splits the rhizome in one pass, and that split is precisely how new plants are made.
Size & spacing
The plant keeps a compact form, climbing to about 12 to 24 inches (30 to 60 cm) tall with a spread of 8 to 12 inches (20 to 30 cm). A footprint that modest slots easily onto a shelf or desk, or into a cluster of other humidity-lovers.
Troubleshooting
Nearly every fault with a peacock plant surfaces on the foliage, and the root cause is usually water or air. The margins and the markings are diagnostic: read them and you can name the problem before it spreads. Find your symptom below, then correct the condition driving it.
Drooping plant with soft stem bases while the soil stays wet
A plant that wilts in soil that never dries is signalling root rot, not drought. Saturated soil holds no air, the roots suffocate, and they rot rather than draw up water. Tip the plant out, cut back the brown, soft roots, and repot into fresh, well-drained mix. Going forward, water only to the point of moist soil and never let it sit waterlogged.
Fix:
- Remove from wet soil and trim rotted roots
- Repot into fresh well-drained mix
- Water only to keep soil moist, never waterlogged
Webbing and pale speckling appearing across the leaves
Dry indoor air is exactly what spider mites thrive in, and once established they spin fine webs on the leaf undersides and puncture cells across the surface, leaving the pale stippled flecks you can see. Hose the foliage off, wipe the leaves clean, and follow up with insecticidal soap or horticultural oil. Push the humidity up, and the conditions stop favoring them.
Fix:
- Rinse foliage and wipe leaves
- Treat with insecticidal soap or horticultural oil
- Increase humidity to discourage mites
Edges of the leaves turning brown and brittle
What you are seeing is tip burn. Fluoride, chlorine, and dissolved salts ride in with tap water, settle in the leaf tissue faster than the plant can move them out, and the margins die back as a result; dry air accelerates the process. Move to distilled or rain water and lift the humidity to 60% or higher. Trimming the worst margins cleans up the look, though dead tissue does not regreen.
Fix:
- Switch to distilled water or rain water
- Raise ambient humidity to 60% or above
- Trim off badly browned margins for appearance
Washed-out markings and bleached patches across the leaves
Excess direct sun is the culprit. Strong rays overload the chlorophyll and pigment in the leaf, burning the surface and draining the peacock-feather markings to a uniform pale green. Return the plant to bright indirect light or part shade and remove the leaves that are badly burned. Fresh foliage comes in carrying the full pattern.
Fix:
- Move the plant to bright indirect light or part shade
- Remove severely scorched leaves
Toxicity
For households with pets or children, the peacock plant is safe. The ASPCA records Calathea as non-toxic to cats, dogs, and horses, and the leaves carry no harmful compounds for other animals or for people. It can go anywhere in the home, a stray nibble included.
Safe for
People · Cats · Dogs · Horses · Rabbits · Livestock · Birds
Cats None
Listed by the ASPCA as non-toxic to cats, so a curious bite carries no poisoning risk. A cat that overdoes it on any houseplant may still bring up the roughage, but nothing in these leaves is harmful.
Dogs None
No concern for dogs. The ASPCA rates the peacock plant safe for them, and the foliage holds no toxic compounds should one decide to chew on it.
Horses None
A horse can browse nearby without risk; both the ASPCA and NC State Extension classify the plant as non-toxic to them.
Rabbits None
The leaves hold nothing that would harm a rabbit. It is not part of their natural diet, so treat an occasional nibble as harmless while hay and greens stay the staple.
Livestock None
Goats, sheep, and cattle run no risk of poisoning from this Marantaceae plant. Being a tropical houseplant, it seldom comes within their reach anyway.
Birds None
There are no toxins in the peacock plant that would affect a pet bird, so a pull at the leaves does no harm.
People None
Fine to keep around children. It is grown for the foliage rather than for the table, but a mouthful poses no poisoning risk to anyone.
How to propagate
Propagation here amounts to a single method, and it overlaps with ordinary upkeep. You split the rhizome at repotting time rather than attempting to root a cutting.
DivisionModerate
Late spring · Several weeks to a few months to establish new growth
Multiplying this plant comes down to one technique, dividing the rhizome, and it lines up neatly with the repotting it asks for about every two years. Work in late spring, teasing the root ball into clumps that each retain a few healthy shoots, then pot them individually and hold them warm and humid. Expect anywhere from a few weeks to a few months before new growth takes hold. Cuttings of stem or leaf will not root, so do not bother.
Myths
You grow the peacock plant for its blooms.
The flowers run small, purple to white, and seldom appear at all on an indoor specimen. The foliage is the whole point, each leaf carrying markings that radiate out like the eye on a peacock feather. The leaves are why it sits on the shelf, never the bloom.
Keeping a peacock plant is a hazard for pets.
Calathea is on the ASPCA non-toxic list for cats, dogs, and horses, and NC State Extension records the same for Goeppertia makoyana. A home full of pets is no obstacle to growing this one.
Calathea makoyana is the right scientific name.
Plant tags keep printing it, but the name is now a synonym. Kew lists the accepted name as Goeppertia makoyana, the outcome of the 2012 reclassification that shifted many Calathea over into Goeppertia.
