Weedy Tulips - T. clusiana
penstemon (Sun, 29 Mar 2015 21:27:34 PDT)

Monsters, you have just made me order the Kew monograph. I had previously been subsisting on various papers and Tulips, Species and Hybrids for the
Gardener, a generalist survey by Richard Wilford, who is at Kew, knows a lot about a lot of bulbs, contributed the cultivation chapter to the monograph and is a fine fellow.

Last I saw, the AGS had it on sale. Nice illustrations, too. Many species reduced to synonymy.
