HPF, is a very bright bloom that stands out. I planted HPF in 2012 and it has grown into a large clump, I shovled off a 6 or 7 fan piece this spring for a trade, and the clump didn't appear any smaller this summer. There seems to be a high scape denisity, the scapes have been loaded with bee pods, every year I have had it, and it blooms well above the foliage. One of my favorites, I should have númerous seedlings from it bloom next year, though my pollen marking process didn't work, so will be unknown crosses. I would recommend HPF to anyone who like bright, large blooms.
