Peniocereus greggii v. transmontanus – Arizona Queen of the Night Cactus Seeds

The Arizona Queen of the Night: a sprawling, pencil-thin grey cactus that hides among desert shrubs all year and then, on a few nights in June, opens enormous white flowers with a scent that carries for hundreds of feet. Below ground it grows a large turnip-like tuber that can weigh many pounds. The transmontanus variety is the Arizona and Sonoran form. A true collector's plant and a fine candidate for a big pot in a warm climate.

Germination

Easy to moderate. Sow in a gritty mix, keep warm (75–85°F) and lightly moist; germination in 1–4 weeks. Seedlings form the tuber quickly, so give them depth.

What you'll receive

Fresh seed in the pack size you choose, with germination instructions included. The first image is an illustration of the species.

Care

Full sun to light shade, very well-drained soil, and a dry winter rest. Hardy to around 20°F when dry. Water deeply but infrequently in summer.

About this seed

This is one of a small number of species we don't yet produce in quantity ourselves, so the seed is sourced from established US growers we trust, then stored cool and dry here on our farm in Blythe, California and sold fresh. Everything else we sell is grown on site in full desert sun.
