It grows at 1,200–3,500 m altitude in the Andes, typically growing in rock crevices, and often close to waterfalls. It is of note as the smallest cactus species in the world, with a mature size of around 10–12 mm diameter. The flowers are white or rarely pink, 6–15 mm long and 5–7 mm diameter.

Dicentra formosa has narrower flowers and longer, more curved outer petal tips. "D. formosa" is related to "Lamprocapnos spectabilis", another popular plant called "bleeding heart", which was formerly placed in the same genus.

There are two subspecies, "Dicentra formosa" subsp. "formosa" and "Dicentra formosa" subsp. "oregona". Subsp. "formosa" grows in the majority of the plant's range, from Vancouver Island and southern British Columbia and south through Washington and Oregon to central California in the Coast Ranges and Cascades, and
