Growing Notes

This palm naturally grows in the gravely cracks between rocks in Isalo national park in Madagascar. As such, we find good drainage is important and root rot occasionally occurs when planted in heavy soil. That said, one member of our team has grown this palm through a few winters in SSZ 16 in heavy shaded clay without trouble, and many other growers promote this palms durability in various soils. If you have experience with this palm in heavy soil we’d love to hear from you!
Given this palms habitat, in tight canyons, it does well in both full sun (where palms high in the canyons grow) and full shade (where lower palms live). Palms in the shade will be thiner trunked and even more lacy and delicate looking, while those in full sun will be stouter and have brighter powdery blue-green leaves.

Special Interest

There are two forms of this palm in Isalo National Park; one grows in shady steep canyons and has a smaller overall stance, the other grows out on open flat rocky ledges in hot baking sun and has a larger stance. Unfortunately, the two forms are not often distinguished in cultivation.

The species ‘glauca’ refers to the glaucous (powdery) blue new growth.
