Positive palmbob On Sep 21, 2005, palmbob from Acton, CA (Zone 8b) wrote:

This is one of the more commonly grown and larger cycads available. It has relatively user-friendly leaves with lancelote spineless leaflets (sometimes very small spines along edges) of a bright, limey green. The leaves can be quite long and this plant will take up a large amount of room in your yard. It is one of the Encephalartos that is a bit happier NOT getting blazing hot sun all day long, and does best in moist, semi-shady yards. I have seen a monster of a plant in Fairchild (Miami), so it obviously loves that hot, humid climate.
