Harrisia fernowii
A Cuban endemic Harrisia that branches from the base into thin, upright to leaning stems 2.5–3 m tall and carries large white night-blooming flowers. The records sit on the hot, low coast of eastern Cuba, where there is a dry winter and a wet season that peaks in May–June. Grow it like a tropical lowland cactus: very bright, warm all year, drier in winter.
Where it grows wild
Recorded mainly along the dry southern coast of eastern Cuba (Guantánamo and Santiago area) and near Holguín. Like other Caribbean Harrisia it most likely grows in coastal dry scrub and thorn woodland on limestone or rocky ground, often scrambling through shrubs.
The climate sites lie at about 10–110 m; few records carry an elevation, but the points suggest coastal lowlands below roughly 200 m.
