Geiger Tree

Cordia Sebestena is a small shapely tree which grows up to be  25″ tall and as wide. It is native to the northern coast of South America, Yucatan, the West Indies, and the Florida Keys (although it it is considered by most to be a native tree, most likely it was introduced).


“The Rough-leaved Cordia

This plant, on account of its large tubular scarlet flowers, is one of the most beautiful of the West Indian trees. I saw only two individuals at Key west, where we supposed, they had been introduced from Cuba. They were about fifteen feet high, the stem having a diameter of only five or six inches. They were in full bloom in the early part of May, and their broad deep green leaves, and splendid red blossoms, mingled with the variety of plants around me, rendered their appearance delightful. Both trees were on private property, and grew in a yard opposite to that of Dr. Strobel, through whose influence I procured a large bough, from which the drawing was made, with assistance of Mr. Lehman. I was informed that they continue to flower nearly the whole summer”

Historians using Key West records have been able to document that Dr. Strobel’s neighbor was a Captain Geiger. The Cordia tree thus became part of Key’s history when the tree took on the additional name of Geiger tree. Named after Captain John H. Geiger, who built his home on Whitehead Street in Key West, the name “Geiger tree” is likely of local origin inspired by Audubon’s engraving of Captain Geiger’s beautiful flowering Cordia tree with white-crowned pigeons sitting in a branch. Audubon’s assistant, George Lehman painted the Geiger tree.
