I have had Spider Spirits blooming since 2014 so 10+ years in the same spot. Performance is variable in my yard as invasive tree roots are prevalent in its location. Bloom size has varied from 4.5" to 8" and scape height has varied up to 35". I have never seen the registered height. Best bud count has been 19 on 4 way branching the same year [and only] year it rebloomed: FFE on 3 May and rebloom on 27 Jun. Normally blooms mid-May which makes it an early-mid here as peak bloom is usually about end of May.. Pollen and pod fertile although pod is difficult. I have bloomed seedlings both ways.
a couple of keeper seedlings:
