Care Guide

💧 Water
☀️ Light Full sun

Red swampfire originates in bright, open habitats and thrives in full sun. It can tolerate partial sun but prefers direct sunlight for optimal growth. This plant, which can be annual or biennial, is known for its sun-loving nature.

Ideal: Full sun
🌡️ Temperature 10–35°C

Red swampfire can tolerate a wide range of temperatures, but its distribution may still be constrained by different combinations of water and heat. It performs best in warm summer climates with sufficient rainfall or watering. Extended periods of cloudy, rainy weather or prolonged high temperatures can raise the chance of Red swampfire dying. In winter, appropriate protection from cold can increase the plant's survival rate.

Ideal temperature: 10–35°C
