Copiapoa longistaminea F.Ritter
Copiapoa de Adriana
Copiapoa calderana subsp. longistaminea, Copiapoa cinerea var. longistaminea
Copiapoa longistaminea is a slow-growing cactus that forms dense cushions of many stems covered with grayish wax and orange wool at the apex. The stems are globose to shortly-cylindrical, up to 20 inches (50 cm) tall, up to 6 inches (15 cm) in diameter, and have 15 to 21 ribs. The spines are straight, up to 1.2 inches (3 cm) long, brownish at first, becoming dark red to black, and finally grey. Flowers are bright yellow, funnel-shaped, and up to 1 inch (2.5 cm) long.
USDA hardiness zones 10b to 11b: from 35 °F (+1.7 °C) to 50 °F (+10 °C).
How to Grow and Care
Despite the extreme and specific conditions in habitat, Copiapoas, as a whole, are surprisingly easy to grow. From seed sewing to the care of mature plants, this genus is very forgiving. While maintaining size, Copiapoa in cultivation will flower from a young age and reliably so each following year.
These cacti want exposure to half or full sun. If they are in full sun, they must be in a position with good air circulation or risk sunburn.
Watering should be extremely poor. The soil must dry out completely between waterings. They should, however, be suspended during mid-summer. In this period, instead of watering, it will be appropriate to spray the plant early in the morning, before the temperature warms up, thus simulating the conditions they would have in their natural environment.
The soil should be formed from a mineral substrate (granite crumbled) mixed with very little universal soil.
