The Quindio wax palm (Ceroxylon quindiuense) is considered the national tree of Colombia. It is naturally distributed in the three Colombian cordilleras, and it grows usually above 2400 m alt. (7900 ft).  Old wax palms can become very tall, up to 60 m tall (200 ft) -they are considered the tallest palms in the world-. 

Here, a 35 year-old wax palm growing at the garden of El Refugio. It is approximately 25 meter (82 ft) tall, and it hasn´t flowered, yet.

The wax palm of the coffee groves (Ceroxylon alpinum) usually grows between 1700 and 2300 m alt.  In comparison with it the latter, this species is hardier and can grow faster. Here, two mature, 23-year-old, female individuals of Ceroxylon alpinum plenty of seeds at El Refugio.  All species of wax palms are dioecious (in other words: there are either male or female plants).
