Tropical evergreen plant (Goeppertia insignis) is a tropical evergreen perennial native to Brazil. It is grown exclusively for its long, elegant, ornamental foliage, as it rarely blooms indoors. Plant grows at a moderate rate indoors but will slow or stop growing if the plant is in unfavorable conditions. Ideal temperatures for this plant are around 60 to 75 degrees Fahrenheit. Cold, dry air, poor ventilation, drafts and sudden temperature changes are all harmful.
Feed your rattlesnake plant every month during the spring and summer growing season. Feed a balanced liquid fertilizer to encourage healthy foliage development.
The leaves of some rattlesnake houseplants tend to point upward at night and drop back down during daylight. This not-so-subtle movement is normal for this type of plant as a way to manage its light and water resources .
Give this plant the humidity, warmth, and filtered sunlight it requires.
