Setiechinopsis mirabilis (Spanish = Flor de adoration)
This tiny plant seems much underrated in cultivation, perhaps because it so easy to grow, notwithstanding this, it is one of the most fascinating and showy species. This species is self-fertile and produces a fruit full of seed per each flower. The fruit dehisce by a longitudinal fissure, and the seeds are also easy to germinate an grow. Flowers are of a superlative beauty, opening in the moonlight on a summer night and lasting for only till dawn, but a number are produced in succession.
