Fouquieria Columnaris
AdvancedFouquieria columnaris
The Boojum Tree, iconic caudex tree of Baja California with tall conical trunk.
About
Fouquieria columnaris, the Boojum Tree, is native to the Baja California Peninsula and is one of the most iconic and bizarre plants on Earth. A tall, tapering columnar trunk—often reaching several meters to over ten meters in habitat—rises straight into the sky, studded with numerous small lateral branches that bear tiny leaves seasonally. Creamy yellow flowers appear at the apex. Growth is extremely slow and wild individuals can exceed 100 years of age. Intense direct sun and extremely porous soil are non-negotiable. Moderate watering during the growing season with significant reduction in winter is correct. Cold tolerance is reasonable. The surreal, conical silhouette sets it apart from virtually all other caudex plants, and it is an aspirational specimen for serious collectors.

Growing Tips
Light & Placement
Strong direct sun is essential. In the growing season, keep it outdoors in a sunny, airy spot to grow a firm, conical trunk.
Watering
Even in the growing season, water sparingly and only after the soil is completely dry. It stores water in the trunk, so wet soil is a bigger risk than drought.
Temperature & Overwintering
It has a fair degree of cold tolerance. Cold combined with wet soil causes damage, though, so keep it dry through the cold months.
Soil & Repotting
An extremely fast-draining mix is essential. Growth is very slow, so repotting only when root-bound, at the start of the growing season, is enough.
