This one is one of best. It is standing up the heat in zone 8 like a trooper. It still needs the insect and disease prevention like everything else but it Responds and lives so it is a keeper.

From the beginning this one starts with verigated seedlings that are a huge silvery green. Following some weeks later with giant red to scarlet red blooms, white throats and white ruffled edges.

You can see this one from quite a distance, this one is a repeat bloomer and we will have to see how well it preforms in the Texas heat
