Calathea Australia Guide, With their paddle-shaped leaves, bold patterns, and striking colour combinations, Calathea plants are a favourite choice for adding a lush, tropical feel to any space. Commonly used for indoor decoration in Australian homes and offices, they bring instant vibrancy and elegance.

This guide covers everything about Calathea in Australia — origins, unique traits, care tips, problem fixes, and styling ideas for homes and offices.

What Is a Calathea? (Introduction to the Genus)

Calathea belongs to the Marantaceae family, which also includes Marantas and Stromanthes. They are native to tropical Central and South America, particularly Brazil’s lush rainforests. In the wild, they thrive under the jungle canopy where light is filtered and humidity is high, which is why they can sometimes be tricky as indoor plants in Australia’s drier climates.

One of the things that makes Calathea special is its nyctinasty — a natural process where the leaves open during the day to catch the light and close at night, almost like hands folding in prayer. This is why they are often called “prayer plants.”

Fun fact: In parts of South America, large Calathea leaves have traditionally been used to wrap food or even make containers — showing that these plants are not only beautiful but also practical.

Why Are Calathea Plants So Popular in Australia?

There’s no doubt that Calathea has become one of the most sought-after indoor plants across Australia in the past few years. But why?

• Striking Patterns: Each variety has its own signature leaf design — from zebra stripes to rosy hues.
• Pet-Friendly: Unlike some indoor plants, Calathea is non-toxic to cats and dogs, which is a huge relief for Aussie pet owners.
• Compact Growth: Most species don’t grow too tall, making them perfect for apartments in Sydney, Brisbane, or Melbourne.
• Decor Appeal: They instantly elevate home décor, blending well with minimalist, boho, or jungle-style interiors.

According to the Royal Horticultural Society (RHS), many Calathea cultivars have even won Awards of Garden Merit thanks to their beauty and adaptability indoors.

Types of Calathea You’ll Love

There are over 200 recognised species of Calathea, though not all are common in Australia. Below are some favourites you’ll likely see in nurseries, online plant shops, or styled interiors.

1. Calathea orbifolia

• It is known for its large, round leaves striped with silvery bands.
• A statement plant that needs a bit of space.
• Sensitive to low humidity, but worth the effort.

2. Makoyana Calathea (Peacock Plant)

• Nicknamed the peacock plant for its feathery green and cream patterns.
• The undersides are deep purple, adding contrast.
• Native to Brazil, but now a common indoor favourite worldwide.

3. Calathea roseopicta

• Features dark green leaves with pinkish centres and purple undersides.
• Popular among Aussies who love colourful plants.

4. Calathea zebrina

• Aptly called the zebra plant because of its velvety green leaves with light stripes.
• Adds texture and drama to indoor spaces.

5. Australian Calathea lancifolia (Rattlesnake Plant)

• Long, wavy leaves patterned with dark green markings.
• Hardy compared to other Calathea species.

6. Crocata Calathea (Eternal Flame)

• This plant is unique for its orange flowers, which contrast with its lush foliage.
• A rare bloomer indoors, but eye-catching when it does.

Each type brings a different personality, so many Australian plant parents end up collecting multiple varieties.

How to Grow Calathea, Calathea Australia Guide,

Light Requirements

Calathea plants love bright, indirect light. Direct sunlight will scorch their leaves, leaving brown patches. Think of where they grow naturally — under forest canopies — and try to mimic that at home.

Tip: North-facing windows in Australia usually provide the best balance of light without too much intensity.

Soil Needs

Calathea prefers a well-draining but moisture-retentive soil. A good indoor mix is:

• 2 parts premium potting mix
• 1 part perlite or pumice
• 1 part coco coir or peat moss

This ensures roots stay moist but not soggy.

Watering

This is where many plant parents struggle. Calathea likes consistently damp soil, but not waterlogging. Use room-temperature, filtered, or rainwater if possible, since tap water in Australia often contains fluoride and chlorine, which can damage the leaves.

Golden rule: Water when the top 2–3 cm of soil feels dry.

Humidity

Being tropical, Calatheas thrive in 60–70% humidity. In drier areas (like Adelaide or Perth), you may need a humidifier, pebble tray, or to group plants together. Bathrooms with good light are also perfect homes for Calathea.

Temperature

Keep them in the 18–26°C range. Cold draughts or sudden temperature drops will stress the plant.

Fertilising

During the active growing season (spring and summer in Australia), feed monthly with a balanced liquid fertiliser diluted to half strength. Avoid over-fertilising as Calathea roots are sensitive.

Common Calathea Problems in Australia (and Fixes)

Even with good care, Calatheas are known for being a little “fussy.” Here are the main problems you might encounter:

Yellow Leaves

• Usually caused by overwatering or poor drainage.
• Solution: Check soil moisture, improve aeration, and reduce watering frequency.

Browning Leaf Edges

• A sign of low humidity or water quality issues.
• Fix: Increase humidity and use filtered/rainwater instead of tap water.

Drooping Leaves

• It could be due to underwatering, cold stress, or root issues.
• Check soil moisture and room temperature.

Leaf Curling

• Typically, from low humidity or too much direct sun.
• Relocate to a more shaded area and mist lightly.

Pests

Calathea can attract spider mites, mealybugs, and aphids. Keep an eye out for tiny webs or sticky residue.

• Use neem oil, insecticidal soap, or a shower rinse to manage pests naturally.

Styling With Calathea Indoors

Beyond plant care, Calatheas are stunning décor pieces. Here are some ideas:

• Living Room Corners: Larger varieties like orbifolia or zebrina make bold statement plants.
• Bathrooms: Perfect for adding a tropical vibe while enjoying the higher humidity.
• Home Offices: Their calming patterns can reduce stress and boost focus.
• Mixed Planter Displays: Pair with ferns, peace lilies, or monsteras for layered greenery.
• Shelves & Stands: Smaller Calatheas look fantastic on plant stands where their patterns can be admired at eye level.

Design tip: Pair them with neutral pots (white, terracotta, or stone) to let the foliage take centre stage.

Are Calatheas Safe for Pets?

Yes! According to the ASPCA, Calathea is non-toxic to cats and dogs. This makes them a great choice for Aussie households where furry friends like to nibble on leaves.

Calathea vs. Maranta: What’s the Difference?

Many people confuse Calathea with Maranta, since both are called prayer plants. The difference lies in:

• Leaf texture: Calathea leaves are usually larger and more patterned.
• Growth habit: Marantas often trail, while Calatheas grow more upright.
• Care needs: Both like humidity, but Marantas are generally easier to manage indoors.
