Why Grow Rattlesnake Plants Indoors?

Rattlesnake Plants are grown as much for their beauty as for their unique behavior. Their long wavy leaves are marked with dark green patterns and rich purple undersides, giving them one of the most striking looks in the Calathea family.

What makes them even more interesting is their daily movement. Like other prayer plants, the leaves fold upward at night and open again in the morning, adding a living, active feel to your indoor space.

They’re also pet-safe, making them a great option for homes with cats and dogs. If you want a tropical houseplant with bold patterns, natural movement, and safe indoor appeal, the Rattlesnake Plant is an easy choice.

One interesting thing about Rattlesnake Plant (Calathea lancifolia) is that like the prayer plant the leaves fold together at night and unfold again in the morning.

Rattlesnake plant Calathea lancifolia has recently been scientifically renamed Goeppertia insignis.

5. Repot them into a larger pot once they’ve outgrown their current one

Rattlesnake Plant Indoor Care

Want more information on caring for your rattlesnake plant? Here is everything you need to know about providing the best growing conditions, propagating, soil, watering, and more.

Rattlesnake Plant Sunlight

Rattlesnake plants (Calathea spp.) are beautiful, low-maintenance houseplants that are easy to care for. 

One of the most important requirements for rattlesnake plants is the right amount of light.

They grow naturally on the shady rainforest floor so they prefer bright indirect light. They do not receive bright sunlight there.

Some plants are more sensitive to light than others. The Rattlesnake plant will suffer scorch marks if they’re exposed to too much sun or even bright indirect lighting from a south-facing window. 

An east or north-facing window would be a perfect spot for your Rattlesnake plant.

The leaf pattern on the Rattlesnakes will begin to fade if they are exposed to too much light or not enough. 

Best Indoor Locations For Rattlesnake Plant

East-Facing Windows

One of the best spots for gentle morning light without harsh sun.

Bright Bathrooms

Ideal because the natural humidity helps prevent crispy leaf edges.

Kitchens

Often a good fit if there is bright filtered light and decent moisture in the air.

North-Facing Rooms

A good lower-light option, though growth may slow.

How Often To Water Rattlesnake Plant

Watering your rattlesnake plant (Calathea Lancifolia) correctly is crucial to keeping it healthy and preventing root rot.

The watering schedule will vary depending on the season and the level of humidity in your home, but as a general rule, you should water your rattlesnake plant every 7-10 days.

Allow the top 2-3 inches of soil to dry out before watering, and then water thoroughly until water runs out the bottom of the pot.

Be sure to empty any drip tray after watering, as sitting water can lead to root rot. 

Rattlesnake Plant Humidity

These plants thrive in moist environments and prefer high humidity levels. They prefer a humidity range of 50-70%.

Along with low to indirect light preferences, these plants require high humidity to mimic their natural habitat . Some calatheas are placed in bathrooms, kitchens, and other areas with high-moisture levels. Calatheas prefer temperatures 60°F / 15°C and above to support healthy growth. These plants are also sensitive to cold air. The ideal temperatures range for these plants is 75°F / 23°C to 85°F / 29°C. https://en.wikipedia.org/wiki/Calathea

If indoor humidity is low or you live in a dry climate you can try placing your plant on a pebble tray or you can mist your plant daily with lukewarm water.

A pebble tray is simply a tray filled with pebbles to which water is added. You don’t want the bottom of your plant’s pot to actually sit in the water.

Rattlesnake Plant temperature

Rattlesnake plants (Calathea spp.) are native to tropical and subtropical regions of Central and South America.

Rattlesnake plants prefer warm, humid climates and bright indirect light. 

The optimum temperature for rattlesnake plants is between 60 and 85 degrees Fahrenheit. Don’t let the temperature go below 60°.

When the temperature gets too cold, the leaves of the plant will begin to drop off and plants may be permanently damaged. 

Rattlesnake Plant Soil

Rattlesnake plant soil should be rich in organic matter and well-draining.

The soil should also be kept evenly moist, but not soggy. When watering, be sure to avoid getting water on the leaves, as this can cause brown spots.

In addition, rattlesnake plants prefer high humidity levels, so misting the leaves occasionally can be beneficial. 

This plant can be grown in any commercial potting mix or in coco coir.

I see recommendations for adding sand to the mix are fairly popular. Don’t do it. Don’t use cactus or succulent soil either.

Sand is heavy and can compact and make drainage slower. Instead to lighten a potting mix add perlite, LECA, or growstones.

Fertilizing Rattlesnake Plant

Rattlesnake plants benefit from being fertilized every few weeks during the growing season.

High-quality, all-purpose plant food will do the trick. Be sure to follow the manufacturer’s instructions, as too much fertilizer can burn the roots of your rattlesnake plant. 

Rattlesnake Plant Repotting

You will probably need to repot your rattlesnake plant every year or two. You will want to have fresh potting mix on hand.

This is also the perfect time to divide your plant if you want to propagate your rattlesnake plant.

You will want a pot that is only an inch or two larger around than the previous one.

Add some soil to the bottom and place your plant inside. You will fill in around the sides with more soil.

You don’t want your plant to sit any deeper than it did before. You can hold the plant up as you fill in around it to control its final height.

Finally, water your plant thoroughly to settle the potting mix and remove any air pockets.

How To Propagate Rattlesnake Plant

Propagating rattlesnake plants is relatively easy and can be done through division.

The best time to do this is when you are repotting your Calathea.

When division is used, the plant is simply divided into two or more sections, each with its own root system. 

Use fresh potting mix in a pot slightly larger than your root ball and plant it at the same depth that it was growing in before.

Propagating rattlesnake plants is a great way to create new plants without having to purchase them from a nursery.

Pruning Rattlesnake Plant

Though rattlesnake plants do not typically need pruning you should remove any dead or damaged leaves as needed. 

This will help the plant provide energy for new growth instead of trying to heal damaged leaves that wont recover.

Common Rattlesnake Plant Problems

Brown leaf edges

Usually caused by low humidity, dry air, or inconsistent watering.

Yellow leaves

Often linked to overwatering or poor drainage.

Curling leaves

A sign the plant is drying out or humidity is too low.

Faded leaf patterns

Usually caused by too much direct light or not enough light.

Drooping leaves

Can happen from cold drafts, dry soil, or sudden stress.

Is Rattlesnake Plant Toxic?

The plant gets its name from the markings on its leaves, which resemble those of a rattlesnake.

Despite its name, the rattlesnake plant is not toxic to humans or pets.

According to the American Society for the Prevention of Cruelty to Animals (ASPCA), Rattlesnake Plant is non-toxic to dogs, cats, and horses. Calathea | ASPCA

However, it is important to keep this plant out of reach of children and pets, as it can cause mild stomach upset if ingested.
