And a nice write up there, too, Dave.
Extra Kudos! I'll have to read the rest later, as I need to get my Scottish Rock Garden Club seed ex order in ASAP. I am a donor this year, and I may have a shot at getting seed of L. monadelphum x L. akkusianum (among others).
Except.... I had to read the L. hansonii article - the only thing disappointing was there were no photos of the natural environment, or the plant in situ.
