Pygmaeocereus bylesianus
A tiny clustering cactus from the coastal fog desert of southern Peru, with short finger-like stems over a thick tuberous root and long-tubed white night flowers. It lives on fog moisture with almost no rain, so it needs bright light, a gritty mix and very careful watering.
Where it grows wild
Grows on sandy or stony coastal hills in the fog desert, often half buried, with the tuberous root storing water between fog seasons.
Recorded at 60-120 m, close to the coast.
