Growing inground in my z9a garden. It is a very small plant, which was planted Fall 2013 and survived are unusually cold and long (for our area) winter. It will be years before its blue coloration offers the dramatic effect I am looking for in this area of my garden.

Most small E. lehmannii are propagated from seed. The descriptions of this plant needs an update.

This is one of the bluest cycads you can find (though there are some green forms). It has almost pure silvery leaves if grown in hot, full sun. Though the leaflets are very sharp and stiff at the tip, they are simple so they don't tend to hook or grab you as you walk by as some of the other blue cycads will. It's pretty slow growing and a plant with any visible caudex/trunk is considered a showpiece.
