Solidago is a new-found host of
Cuscuta which prefers native
Urtica (and a few other species); last year I found that
Cuscuta is not as vital on
Solidago as it is on
Urtica (it only bore few fruit on the former), and the same was true this year - only that this year's growth of
Cuscuta was much richer, and it reached fruiting stage on many
Soldiago plants too - like on this one here.
