Agave isthmensis comes from the Isthmus of Tehuantepec in southern Mexico. Plants form small rosettes to about 10-12 inches tall by 12-15 inches across. This one does produce offsets and will make small clusters of rosettes. Powdery blue leaves are short and broadly spoon shaped. Protect from frost in the winter. Currently there are two forms in cultivation; “coastal” from near Salina Cruz, Oaxaca and “inland” from near Santiago La Ollaga, Oaxaca. The “coastal” form is the bigger of the two, offsets less profusely, and tends to have smooth leaves while the “inland” form is the smaller of the two, offsets more profusely, and tends to have leaves that are slightly rough to the touch.
