|Ceroxylon quindiuense growing wild in Cocora Valley near Salento, Colombia|
The wax palm grows up to 50 meters (160 ft) (rarely to 60 meters (200 ft)) tall in good growing conditions and is not only the tallest palm but the tallest monocot in the world. The leaves are dark green and grayish, with a petiole up to 2 meters (6.6 ft) long. The trunk is cylindrical, smooth, light colored and covered with wax, When the leaves die they fall and this forms a dark ring around the trunk. The palm is recognized as the national tree of Colombia, and since the implementation of the law 61 of 1985 is legally a protected species. Ceroxylon quindiuense has an extremely slow growth and can live up to one hundred years. It was observed by Alexander von Humboldt, for the first time, in 1801.
Wax palms provide habitats for many unique life forms, including endangered species such as the Loro Orejiamarillo (yellow-eared parrot) Ognorhynchus icterotis. It grows in groups spread-out over the hills of the western side of the Andean mountains, between 2,500–2,800 meters (8,200–9,200 ft) above sea level. Its habitat is sandy soils with a high acidity, and an average rainfall of 1800 mm/year. It has a required temperature range between 12–19 °C (54–66 °F).
Threat of extinction 
The palm faced extinction due to human action. The wax of the trunk was used to make candles, until the introduction of electricity. The outer part of the stem of the palm has been used locally for building houses, and was used to build water supply systems for poor farmers. The fruit was used as food for cattle and pigs. The leaves were extensively used in the Catholic celebrations of Palm Sunday. All of these circumstances produced a drastic reduction of the number of wax palms, which motivated the Colombian government of Belisario Betancur to begin providing protection for the remaining trees.
Cultivation and uses 
In its natural environment, it can tolerate occasional frosts in brief periods of time and it is planted as an ornamental at sea level in California, Southern Europe, New Zealand, and Southern Australia.
