I'm not sure why either Zoia, but now that I see 'Holiday Delight', I think I would have a hard time telling them apart if they were not side by side.
I have 'Outrageous' and just noticed that the database says it is 22" tall. However, in my garden it gets taller than that. This pictures shows 'Outrageous' in the center. 'Autumn Wood' (24") is the shorter one to the right and 'Lavender Blue Baby' (28") is behind that. 'Bali Watercolor' (35") at left and the 'Becky' shasta daisies get around 36" tall. So odd though... 'Lea Ann Williams' is the pink bloom behind 'Lavender Blue Baby' and it is only registered at 22" also. It does have varying heights of scapes though. Things that make you go hmmmm.
