Care Guide

☀️ Light Full sun

Slender westringia comes from open habitats, such as sunny meadows and the edges of forests, which supply plenty of light. It thrives in Full Sun but can also tolerate Partial Sun, adapting well to different sunlight conditions.

Ideal: Full sun
🌡️ Temperature 15–37.8°C

Slender westringia is highly adaptable to a variety of climates, from blazing summers to cold winters. Still, it has an optimal temperature range for healthy growth. If temperatures rise too high, the plant can experience heat and humidity stress that may kill it. In locations where temperatures approach the lower bound of its cold tolerance, providing insulation is important to protect the plant.
