Description
Setiechinopsis mirabilisSN|3878]]SN|3878]] is a very small cactus (usually) solitary. The plants are easily grown from seed and providing good cultural conditions they may begin to flower in their second year.
Flowers
Last for only one night, but a number are produced in succession.
Blooming Season
Summer, the blooms open at sun set and last only a few hours.The spicy exotic perfume and long, narrow flower tube suggest that the natural pollinator must be a long-tongued moth.
Stem
Dark brown, cylindrical which seldom grows taller than 15 cm, 2.5 cm in diameter. The plants seem to die long before this, and are best replaced with fresh seed-raised ones.
Fruits
Drying at maturity an opening laterally by a longitudinal fissures, with numerous seed.
