If you were st D.C in Spring then the nursery was there 2 years ago. But lots of others sell Sanguisorba, especially S. canadensis. They have 'bottle brush flowers on tall stems (well that one does, there are dwarf ones too).
Bought 25 quids worth of plants, but no Geums, he had sold out (end of season really). No Asters as they were mostly A. novi-anglia which die of mildew here and what he had left of the other types we already have. Might have spent more but his card machine was bust and that was all the money we had.
Some of the Geums were in flower, Mai Tai is lovely, but there is a long waiting list for it.
Lots of pictures waiting to be processed.
