Copiapoa marginata

Flowers: yellow, it flowers when quite small.

Blooming season: Spring and summer

Cultivation and propagation: These plants are susceptible to overwatering. They require also an appropriate air circulation. Copiapoas are summer grower species, easy to cultivate.
Growth rate: This is a slow growing cactus.

Watering: It requires light but regular waterings in the Summer, but let the soil mix dry between waterings. Do not overwater (rot prone), it must be strictly kept dry throughout the winter.

Hardiness: Not highly tolerant of a great deal of frost. They need to be kept in a cool place during winter rest and are resistant to light frost if kept on the dry side prior to, and during, cold weather (they are hardy to -2°C short periods).
Exposition: Requires full sun or light shade and careful watering to keep plant compact with strong colored spines. Tends to bronze in strong light, which encourages flowering and heavy spine production. Light shadow might be useful in the hottest summer days.
