About

Fremontodendron mexicanum is a rare species of shrub in the mallow family known by the common names Mexican flannelbush, Mexican fremontia, and Southern flannelbush, that is endemic to the central Peninsular Ranges in Mexico and the United States.

How to grow it

Fremontodendron mexicanum is cultivated as an ornamental plant by specialty plant nurseries, for planting in native plant, drought tolerant, and wildlife gardens, and in natural landscaping and habitat restoration projects.

Cultivated plants need good drainage, and no supplemental summer water when established.

Where it grows

The species is known from about ten occurrences in northern Baja California state and adjacent southern San Diego County, California. However, it has most recently been confirmed to exist in only two of those locales currently. The shrub grows generally on alluvial plains, in California montane chaparral and woodlands and temperate coniferous forest habitats, among Tecate cypress (Cupressus forbesii) trees.
