Summary

Fouquieria formosa, commonly known as Palo Santo, Rabo de Iguana, or Rosalillo, is a small deciduous tree or large shrub native to the tropical deciduous forests and arid tropical scrublands of central and southern Mexico, particularly thriving on rocky alluvial slopes and valleys at elevations ranging from 330 to 7,900 feet. It can grow up to 26 feet tall and is characterized by its dichotomously branched stems with spines. The plant is notable for its deep orange-red to yellow-orange tubular flowers, which bloom from late winter to early spring and attract pollinators such as hummingbirds.

Fouquieria formosa is appreciated for its striking floral display and is used in xeriscaping, ornamental gardens, and as a specimen plant in regions with a suitable climate. It requires minimal maintenance once established and is drought-tolerant, making it ideal for water-wise gardens. This species prefers well-drained soils, tolerates poor soil conditions, and thrives in full sun to partial shade. While not commonly available in cultivation, it can be propagated from seed or cuttings. Gardeners should be aware that the spines can be sharp and may require careful placement in the landscape to avoid injury.CC BY-SA 4.0
