Care Guide

💧 Water
☀️ Light Partial sun

Cape flower is native to habitats like forest understories and rocky sites that offer natural shade. It prefers partial sun but will tolerate full sun or full shade, illustrating its versatility and hardiness.

Ideal: Partial sun
🌡️ Temperature 15–35°C

The Cape flower can tolerate a wide range of temperatures, but its distribution may still be restricted by different combinations of moisture and heat. It does best in warm summer climates with sufficient rainfall or watering. Extended periods of cloudy, rainy weather or prolonged high temperatures can raise the chances of the Cape flower dying. In winter, adequate protection from cold can increase the plant's survival rate.
