My earlier blooming varieties are just plain "odd" this year and it is a problem when they are seedlings under evaluation for introduction. I have "mixed clumps".....with shorter than normal scapes in the middle of the clump and a lone "normal scape" or two out toward the edges of the clump. I've also seen the "instant rebloom" scape (which is usually slightly shorter) bloom before the main scape this year. Mother Nature did a number on us with a hard winter and cold spring which often does affect early bloomers. Thankfully, the mid to late bloomers look like they should.
