In other posts I’ve discussed Dioon edule, a typically small to medium sized sun-loving cycad from Mexico. There are known to be about six different varieties of this species – all from different localities. The variety on sale here is from the Mexican state of Queretaro. Leaves are typically blue in full bright sun. Leaves are about 4 feet long and leaflets are thin, coming to a pointed end. Mature height after a few decades may be six feet with an trunk height of 18 inches. Cold tolerance is excellent, being able to take cold weather into the teens F. The band size on sale are not new seedlings but rather established older (five year old) plants with an average caudex of 1.5 to 2 inches. The bands are shown in the first five photos below. These are hard to find and easy to mail order. Last photo by MARK MASON.
