Lately I’ve been taken by this thistle,* which seems to be more prevalent this year than in years past:
Turns out it’s Crisium arvense, Canadian (or Canada) thistle, and its proliferation isn’t likely to be just a matter of me noticing it – entire on-line forums are dedicated to sharing tips on its eradication. Apparently it grows from root “colonies,” thrives on being cut, and produces seeds which are both plentiful and viable within a couple of days of the appearance of flowers.
Still, it’s beautiful, so enjoy it from a distance, ‘k?
Edit:

I was trying, as yet unsuccessfully, to identify it (it’s not a thistle) and got them mixed up. Sorry!

Hill, yew slippery gal – long time no see! (Yeah, I know, “Look who’s talkin’!”) 😆 I’ll have to throw some Comp’ny Vittles on the next post, in case you come back!
And yeah, they’re beautiful, but really gnarly to handle, the leaves being festooned with nasty needles…
(This is where folks from the Southwest roll their eyes and mutter, “You have NO IDEA!”) 😉
Thanks for stopping by, you two, dinner will be ready in five!
