i read (on eattheweeds.com) that all thistles in cirsium and carduus genera are edible. how do i go about finding out if a certain thistle-looking plant is in those genera? what distinctive characteristics do they have?
is there a sort of rule of thumb for edible thistles or am i going to have to learn to tell each thistle apart?
i appreciate any help i can get on this, thanks :p

There is no rule of thumb. What you have to do is find out which ones grow in your area. Usually there are only two or three. Generally they have a shaving brush blossom and spines that will not soften when cooked.

Don't confuse them with sow thistles, which are a sonchus, not a true thistle. Sonchus, however, are edible as well.

Oh, and thanks for the plug. Eattheweeds is my site.

i better get learning my local thistles then :D:
i live in ontario, canada. are there any thistles that live in my neck of the woods that are easy to identify?
i tried what i'm pretty sure was a bull thistle. i identified it by the bristles on top of the leaf, which i read were distintive, but i've looked at other thistles which have different leaf shapes (from what i could remember) and they had very sparse bristles also.
it seems like the differences between thistles are very subtle :xeye:

and no problem for mentioning your site. i've gone there so often, it's the least i could do! :D:

i don't suppose you could point in the direction to an online source that could teach me to identify thistles. for some reason i'm having a lot of trouble finding websites that will tell me which tell-tale characteristics each thistle has :xeye:
