I am not sure if the seed pods I saw in Ouranoupolis in August are longer than the one you showed below, John, kind of difficult to measure from where I was standing, but I must say was quite surprised to see such voluptuous growth this far north, the top of the house was covered.
This is not far from our house, only 12 km across the bay (but 45 km driving around the bay). I thought it would not be hardy enough in this area, but maybe Ouranoupolis is more sheltered than our place?
