Here in Brampton ON we have several varieties finished and several are still in bloom. P. tenuifolia, Species'Mollis', Little Red Gem, Smouthi, Peter Barr, Fantasia,Starlight, Mlokosewitchii from seed have all finished flowering. Athena, Early Scout, Claire de Lune, Illini Belle, Cora Louise are in bloom now with many more to come.
The weather this year has been different than most. Blooms are early and not lasting as long as we would wish. One day its very hot (like August hot 27 / 28 with humidity making it 30+) and that night very cool or calling for frost.
