Origin and Habitat: Mexico (Baja California: Only occurs naturally on the island of Cedros, off the west coast of northern Baja California and possibly on a neighboring island, West San Benitos, with some reports of it on the adjacent peninsula.)
Habitat: with a balanced and relatively high average temperature, low rainfall but relatively high humidity and specific soil composition (these conditions are difficult to imitate in cultivation, and make this species relatively problematic to grow.
Cultivation and Propagation: Use very draining soil, water during the aestival growth cycle (this plant need plenty of water) But it's necessary to avoid wetting the bodies of these plants while they are in sunlight. A wet cactus in the sunlight can cause sun burning which can lead to scars or even fungal infections and death. Needs full sun. Keep dry at 50°F (10°C) in winter, but it can tolerate sporadic light frost.
Propagation: Seeds are the only way of reproducing. The seeds germinate readily.
Remarks: It is often recommended to graft young seedlings on Eriocereus jusbertii. But plants can grow on their own roots for ages if watered carefully.
