Angelo: Sorry for the slow response. We got our original plants of this from Patty Allen, so we both have the same clone. I seem to recall that she got it from a gardener in Texas and had someone to identify it as G. byzantinus. I certainly agree that it looks and grows more like G. italicus. If so, I'm wondering if anyone actually has the true G. byzantinus.
