What Alex said is correct. The ones we got this past late May or maybe early June we will not be able to divide until next fall due to them not increasing well the first season. Not all but some did bloom with a few buds and really short scapes. I got the dip collection and it has increased a tad bit better than James' tets but not enough to divide.
I did order 4 of Polston's toothy ones this year; there was 2 other ones I wanted but they were sold out already unless you bought the whole collection which I did not want.
I know they will be small but I am used to getting small ones from the Northern hybridizers.
