Truly ''R. glauca'' is one of the most promising palms for cultivation Madagascar has to offer. Tolerant of soil, exposure, and water needs, ''Ravenea glauca'' is proving itself in a wide range of growing conditions while reliable as a gorgeous mid-sized palm. Perhaps this is due to its natural conditions growing in deeply shaded, yet still hot deep canyons, sometimes very wet and sometimes very dry, and when tall enough, exposed to scorching sun. Few palms are as forgiving and as beautiful at the same time. Because ''R. glauca'', like all Raveneas, is [[dioecious]], growers would do well to assure this palm sets viable seed in cultivation by planting groups separated from other Raveneas. These palms are considered endangered in habitat. | Truly ''R. glauca'' is one of the most promising palms for cultivation Madagascar has to offer.

The most curious thing about this palm has already been alluded to above. It not only tolerates such a wide range of conditions and outright abuse, it is remarkably bug and pathogen resistent. And does it all while still looking pampered. | The most curious thing about this palm has already been alluded to above.

Habitat and Distribution
Ravenea glauca is endemic to seasonally dry forest and extremely deep ravines and canyons in south central Madagascar at elevations from 2200 to 4000 ft.
Description
Some have adopted a common name of "Mini-Majesty" thinking this species is a smaller version of Ravenea rivularis. However, the two have little in common, with the former possessing a much more delicate appearance and much slimmer trunk. Neither does R. glauca share its "big brother's" affinity for water. The "glauca" in the binomial refers to the glaucous blue appearance of the new growth and the coloring these sometimes retain when grown in a hot, dry location. As can be seen from the photos, this species can attain heights more than the 15-26 ft that most references claim, on a slender 3-4 inch trunk (6-8 inch in cultivation). They can hold as many as 18-20 graceful 4-6 ft long leaves on 3-6 inch petioles.

Tolerant of soil, exposure, and water needs, Ravenea glauca is proving itself in a wide range of growing conditions while reliable as a gorgeous mid-sized palm. Perhaps this is due to its natural conditions growing in deeply shaded, yet still hot deep canyons, sometimes very wet and sometimes very dry, and when tall enough, exposed to scorching sun.

Because R. glauca, like all Raveneas, is dioecious, growers would do well to assure this palm sets viable seed in cultivation by planting groups separated from other Raveneas.
