This is the largest and most extreme of my dianthums. I can't imagine how parishii would have got mixed in. I have others which are more in line with the mainstream form. This one has by far the largest size, darkest colour and biggest spacing between the blooms. I have had it for many years, but have struggled to grow it. Each time as it matured a growth, it would develop rot and the the whole process would begin again while the next baby lead matured. I estimate this is the first bloom in twenty years. At long last it seems to be growing strongly and I hope it will not take as long to rebloom.
