Coast sandbur thrives with ample sunlight, which is essential for its healthy development. Because of the environment it originated from, it can tolerate not having full sun all day. Still, very limited light or excessive sunlight can impede its growth.

Ideal: Full sun
🌡️ Temperature 10–35°C

Coast sandbur is a plant adapted to temperate environments and prefers temperatures of 68 to 95 °F (20 to 35 ℃). In cooler climes, consider sheltering it during periods of extreme cold to prevent damage.

Ideal temperature: 10–35°C
