Bark is way cool, looks like a an elephant leg.
Propagation is not really hard, but timing is everything. Trees are estimated to live 15-20 years in their native habitat, but may live longer without fires that rip though that habitat. The trees at the Arboretum have to be 25 years old. But they are intolerant to frost with the tips burning and they do seem to die without much notice.
Hardly… silver foliage is a gardeners dream.
