🌡️ Temperature 20–37.8°C
Purple false erantheum comes from tropical areas, where the climate is generally warm and humid. Consequently, it is adapted to high temperatures and moisture. It does not tolerate sudden temperature changes and prefers a steady thermal environment, so avoiding temperature fluctuations indoors is important. It typically cannot endure cold conditions and requires warmer temperatures for growth. If the ambient temperature falls too low, the plant may stop growing or even die.
