Horst...........your Y. fila x rostrata is growing fast.....it looks great. This is a really nice hybrid.Nice to see the reverse hybrids with arkansana/angustissima. It will be interesting to see the differences in blooms.A few more photos of the other Y. fila x rostratas (Benny) in my garden.Y. fila x rostrata #1Y. fila x rostrata #2 (your form)Y. fila x rostrata #3Y. fila x rostrata #4 (this has a 'flat' leaf head.....not sure why.....it looks different from the others)
