Rattlesnake plant (Goeppertia insignis) is a tropical evergreen perennial native to Brazil, commonly grown as an indoor houseplant. It can be tricky to nurture and isn't the easiest houseplant for beginners since it has particular heat, light and moisture requirements.
But, if you give it the care it needs, you will be rewarded with an impressive foliage display with a wavy pattern along the edges and variegated with shades of greens. Even the undersides of the foliage are eye-catching with their beautiful purplish-red tones.
In its native habitat in Hawaii, Florida, and California, the rattlesnake plant produces small yellow flowers in late spring. But as a houseplant, it is grown exclusively for its long, elegant, ornamental foliage, as it rarely blooms indoors.
Plants typically grow to about 20 inches tall when grown as houseplants in greenhouses or terrariums. Rattlesnake plant grows at a moderate rate indoors but will slow or stop growing if it's in unfavorable conditions.

Rattlesnake Plant Care
Here are the main care requirements for growing a rattlesnake plant.
- Place in bright, indirect light away from vents and drafty areas.
- Plant in a well-draining soil that can be kept moist.
- Keep the plant's environment humid through misting, using a humidifier, or other methods.
- Water enough to keep soil moist in the summer. In the winter, allow the top soil to dry out between waterings.
- Avoid leaving the plant in standing water.
- Feed regularly during the spring and summer months.
Light
Keep your rattlesnake plant in a space with filtered light. If you want to place your plant in a window, select one that doesn't have intense afternoon sun streaming through it, or diffuse the light with drapes. A bright spot in a well-lit room works well.
Soil
Choose a well-draining soil. Although these plants can't handle standing water, they like to be kept moist. A light sandy soil or a potting mix of two parts peat moss and one part perlite works well. Rattlesnake plant prefers slightly acidic or neutral pH levels, but alkaline soils should be avoided.
Water
Water your rattlesnake plant frequently in the summer to keep the soil moist. During the winter season, allow the top layer of soil to dry out before watering again.
If the leaves start to turn yellow, you may be overwatering. Conversely, if the leaves begin to curl unattractively they aren't receiving enough water.
Water the plant until it just starts to trickle out of drainage holes (not so much that water is streaming out of the bottom). Do not let the plant sit in excess water.
Temperature and Humidity
Keep your rattlesnake plant in temperatures between 60 to 75 degrees Fahrenheit. Do not place the plant near air conditioning units and heating systems since dry air, poor ventilation, and sudden temperature changes are harmful.
Create a humid environment by standing your potted plant on a tray with pebbles. This helps create a moist environment. You can also regularly mist your plant, bring it into the bathroom when showering, and invest in a humidifier.
Fertilizer
Feed your rattlesnake plant every month during the spring and summer growing season. Use a balanced liquid fertilizer to encourage healthy foliage development, and follow the product label instructions.
Types of Rattlesnake Plant
There are cultivars of G. insignis, but there are other species of Goeppertia houseplants with similar care needs:
- Goeppertia majestica is a larger 3-foot plant with wider egg-shaped leaves, green with thin stripes of color.
- Goeppertia makoyana (cathedral windows, peacock plant) is a 40-inch-tall plant with wide showy leaves resembling a peacock's tail.
- Goeppertia micans (prayer plant) is a 12- to 16-inch tall plant with leaves that fold together at night.
- Goeppertia zebrina (zebra plant) is a 3-foot-tall plant with light green leaves striped with darker green.
Pruning
The only pruning required is to remove dead or drying leaves. Simply cut the leaves with scissors or pruning shears at the spot where the leaves meet the stem or base of the plant.
Propagating Rattlesnake Plant
These plants are easy to propagate by division once they are well established and active growth slows down, but propagation by seed is extremely difficult. You can undertake the process of dividing in the spring when you are planning to repot the plant.
- Water your plant the day before to lessen the amount of stress on the plant.
- Choose a pot that's large enough for the new root ball you will create when dividing the plant. A plastic, metal, or glazed ceramic pot with drainage holes is best since the plant requires a moist environment.
- Fill the pot about 1/3 of the way with potting soil with some perlite mixed in.
- Place the potted plant on its side so you can easily slide the root ball out of the container.
- Gently brush soil from the roots and begin to carefully tease the roots apart with your fingers. Separate the roots where it seems natural, but don't force any roots to break apart. Trim off any damaged or diseased parts of the root with gardening scissors.
- Place the divided root ball into its new container and backfill with soil, using some of the soil from the original pot.
- Water the newly potted plant until water drains from the bottom of the container.
- Optional: Mimic a greenhouse effect by placing a clear plastic bag loosely over the plant and container until you see that it's growing. Then you can remove the plastic and care for it normally.
Common Pests
The thick leaves of your rattlesnake plant may entice pests. Look underneath leaves for the usual suspects, including aphids, mealybugs, and spider mites. Treat the problem quickly with gentle insecticidal soap, neem oil, or simply wash the insects off the leaves with a soft cloth dipped in soapy water.
Common Problems With Rattlesnake Plants
Leaf Color or Pattern Fading
A key consideration for any rattlesnake plant is proper lighting. If it gets too much direct sunlight, green spots may appear on the leaves; too little light and the vibrant spotted markings may begin to fade.
Limp or Rotting Stems
There are two possibilities for problematic stems: overwatering or drafts. Giving your plant too much water when the temperature drops can cause the stems to become limp, and sitting in water can cause the roots to rot, which can kill the plant. Try moving the plant to a warmer space with no extreme temperature fluctuations to see how the plant fares.
Leaf Edges Turning Brown
Brown leaf edges signal that the plant needs more humidity in its environment or could be a result of using commercial leaf shine. In addition to brown leaf tips, overly dry air can result in the foliage curling up. Take steps to add humidity to the area where the plant lives and stick to a simple damp cloth to remove any dust or debris instead.
