Hybridized by Curt Hanson and introduced in 2004, Jerry Hyatt is a semi-evergreen tetraploid that grows about 27-28" tall and has a 6" bloom. He's an award winner that received an Honorable Mention Award in 2007 and an Award of Merit in 2012. Jerry is a new plant to my garden and thankfully he appears to be happy here.
Jerry Hyatt is a child of the tetraploid Trahlyta, which is where the grey/violet tones come from. I grow the diploid version of Trahlyta, which I have had for many years (and would never part with).
