Echinopsis obrepanda or Violet Easter Lily Cactus, a native of Bolivia, is a small cactus reaching about 6 inches (15 cm) tall by 7 inches (17.5 cm) thick. It has 17-18 thick ribs with 1½ inch (4 cm) awl-shaped spines. They easy to grow and make a great cactus for beginners.
Blooming Time: In spring, the showy white to purplish flowers are 4 inches (10 cm) across to 8 inches (20 cm) long.
Culture: Echinopsis obrepanda need full sun to partial shade with a well-drained soil mix. We use a soil mix consisting of 2 parts sand to 1 part peat moss to 1 part loam. To this mix, small pea gravel is added to ensure good drainage. In the spring, when new growth has begun, the plants are watered on a regular basis, but are allowed to dry in between watering. They are fertilized only once during the growing season. In the fall and winter, they should be watered only enough to keep them from shriveling.
Propagation: Echinopsis obrepanda are propagated in spring by the removal of offsets or by seed. Seed should be sown in a sandy mix and germinate in 14 to 21 days at 68° to 70° F (20-21° C).
Echinopsis obrepanda was featured as Plant of the Week July 26-August 1, 2002.
