Ahhh, violet or purple ... we're at the end of this week's rainbow.
I'm not a botanist but I'm pretty sure this is Aconite (Aconitum napellus) aka Monkshood. According to Planet Deadly it is poisonous? I did some more research and found that it is also a useful herb but that the root is extremely toxic. For more info take a look at this herbal remedies site.
If anyone can validate my assumption, please do!
The fine spider webs caught my eye when I was snapping this one.
An extra picture for good measure. This one is a bit more on the pink side but I like it just the same.
Thanks for creating this challenge.
