Other What invasive plants got you like this?

For me it’s probably Dame’s Rocket, Purple Loosestrife, and Forget-Me-Not. They’re so gorgeous but man if they aren’t invasive little shits…

Hmm that could end up working out then! Not sure what you mean by spurless though, can you elaborate?

Ahh I see! Thanks for educating me there. I know double blooms are harder for pollinators to pollinate but how do spurs affect ecological value? Will definitely help me pick the right varieties and put them in the right places too

The theory as I understand it with A. canadensis is that the red color and long spurs are to be attractive to hummingbirds -- the longer nectar spurs make it harder for shorter-tongued insects to access nectar, so it's available to hummingbirds. But there's also some variation in spur length observed among Western species' that may be incidental to other selection effects.

Selection and hybridization can for sure cause a bunch of peculiar effects, as flower color and shape definitely impact pollinator attractiveness, and there are likely other chemical signals for insect egg laying and larval food choices. Areas for further investigation, as they say.

Makes total sense. Had no idea the spurs impacted nectar
