Rattlesnake plants, also known as Calathea Lancifolia or Prayer Plants, are a popular houseplant due to their unique and striking appearance. They are native to the rainforests of Brazil and are known for their vibrant foliage and delicate flowers. These plants require specific care to thrive, but with the right techniques, they can be grown successfully indoors.

Types of Rattlesnake Plants

Although there are varieties of Goeppertia insignis, additional species have comparable care requirements:

  • The bigger, 3-foot-tall Goeppertia majestica has broader, egg-shaped leaves that are green with tiny color stripes.

  • A 40-inch-tall plant known as Goeppertia makoyana, or "cathedral windows," has broad, colorful leaves that resemble a peacock's tail.

  • A 12- to 16-inch tall plant known as the "prayer plant" has leaves that fold over at night.

  • A 3-foot-tall plant known as a "zebra plant," Goeppertia zebrina, has light green leaves with darker green stripes.

How to Grow and Care for Rattlesnake Plant

The rattlesnake plant (Calathea lancifolia) is a tropical houseplant that has striking foliage with dark green spots and purple undersides. It gets its name from the resemblance of its leaves to the tail of a rattlesnake. This plant prefers bright indirect light, high humidity, and moist but well-drained soil. It is sensitive to cold, drought, and direct sun, so it needs some extra care to thrive indoors.

Choosing the Right Location

Rattlesnake plants require bright, indirect sunlight to grow, so it is essential to choose the right location inside your home. Place the plant near a window that receives indirect sunlight, and avoid exposing it to direct sunlight because direct sunlight can cause the leaves to scorch.

Soil Requirements

Rattlesnake plants require well-draining soil that retains moisture. A mix of potting soil, peat moss, and perlite will provide the ideal soil conditions for the plant. The soil should be kept moist, but not waterlogged or soggy.

Watering

Rattlesnake plants require consistent moisture to grow, but don't overwater them. Water the plant when the top inch of soil feels dry to the touch. Ensure the pot has proper drainage and remove any excess water that accumulates in the saucer. During the winter months, reduce the frequency of watering to prevent the soil from becoming waterlogged.

Humidity

Rattlesnake plants are sensitive to dry air and require a humid environment to thrive. Increase the humidity around the plant by placing a tray of water near it or using a humidifier. Misting the leaves with water once or twice a week can also help to increase the humidity.

Temperature Requirements

Rattlesnake plants prefer warm temperatures between 60-80°F. Avoid placing the plant in cold drafts or near air conditioning units that may cause the temperature to drop. Keep the plant away from heating vents that may cause the air to become too dry.

Fertilizer

Rattlesnake plants require regular fertilization during the growing season [2] to promote healthy growth. Use a balanced fertilizer every four weeks during the spring and summer months.

Propagation

Rattlesnake plants can be propagated through division or stem cuttings. To propagate through division, remove the plant from its pot, and separate the root ball into sections with a clean, sharp knife. Plant each section in a new pot with fresh soil, and maintain the same care requirements as the parent plant.

To propagate through stem cuttings, select a healthy stem with at least two leaves, and cut it just below a node. Dip the cut end into rooting hormone and plant it in a pot with moist soil. Cover the pot with plastic wrap to increase humidity and maintain consistent moisture. After two to three weeks, the stem should begin to root.

Common Problems With Rattlesnake Plants

Rattlesnake plants are beautiful houseplants with striking foliage, but they can also be tricky to care for. Some of the common problems that rattlesnake plants face are overwatering, low humidity, pests, and diseases. Here are some tips on how to avoid and fix these issues:
  • Overwatering: Rattlesnake plants don't like to sit in soggy soil, which can cause root rot and fungal infections. To prevent this, water your plant only when the top inch of the soil feels dry to the touch, and make sure the pot has good drainage holes. You can also use a moisture meter to check the soil moisture level before watering.

  • Low humidity: Rattlesnake plants are native to tropical rainforests, so they prefer high humidity levels. If the air in your home is too dry, your plant may develop brown tips, curling leaves, or leaf drop. To increase the humidity, you can mist your plant regularly, use a humidifier, or place your plant on a tray of pebbles with water.

  • Pests: Rattlesnake plants can attract common houseplant pests [3] like spider mites, mealybugs, and scale insects. These pests can suck the sap from your plant and cause yellowing, wilting, or stunted growth. To get rid of them, you can wipe your plant with a damp cloth or cotton swab dipped in alcohol, spray your plant with insecticidal soap or neem oil, or use sticky traps or predatory insects.

  • Diseases: Rattlesnake plants can also suffer from fungal or bacterial diseases that can cause spots, lesions, or blisters on the leaves. These diseases can spread quickly and kill your plant if left untreated. To prevent this, you should avoid overwatering, keep your plant clean and well-ventilated, and remove any infected leaves as soon as possible. You can also use fungicides or bactericides to treat your plant if needed.

FAQs

Rattlesnake plant (Calathea lancifolia) is a tropical houseplant that has striking foliage with dark green spots and wavy edges. It is also known as prayer plant because it folds its leaves at night. Here are some common questions and answers about how to grow and care for this beautiful plant.

How much light does a rattlesnake plant need?

Rattlesnake plants prefer bright indirect light, but can tolerate low light conditions. Avoid direct sunlight, as it can scorch the leaves and cause them to lose their color.

How often should I water rattlesnake plants?

Rattlesnake plants like moist but well-drained soil. Water it when the top inch of soil feels dry, and make sure to empty the drainage tray after watering. Do not let the soil dry out completely or become soggy, as this can cause root rot or leaf curling.

What is the best temperature and humidity for rattlesnake plants?

Rattlesnake plant thrives in warm and humid environments, similar to its native habitat in Brazil. The ideal temperature range is 65°F to 85°F, and the humidity level should be above 50%. You can increase the humidity by misting the plant regularly, placing it on a pebble tray with water, or using a humidifier.

How do I fertilize rattlesnake plants?

Rattlesnake plant does not need a lot of fertilizer, but you can feed it once a month during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength. Do not fertilize in winter, when the plant is dormant.
