That does not look like the fleabane I know. But what I know is not
Erigeron Stigosus Yours does look to be a member of the aster family. I see the link to your source but I would want to know more about the plant than it just looks like...
Over at Eat The Weeds, Green Deane is fond of giving the anagram ITEM.
Identification - you have to get botanical, at least know leaf and stem shapes and textures.
Time of year - Is it the right time of year for it to appear? Giant Hogweed is up before Hemlock which is up before Queen Ann's Lace. But they all look the same depending on growth stage.
Environment - Where is it growing? Many plants want a specific environment. If they are out of it there is some reason. Cattail always wants to grow in the wet. If the environment is dry today, was it in the earlier season? So don't be confused if a plant is growing where it doesn't make sense. On the other hand, if you can't explain why, then it probably isn't the one you think it is.
Method of preparation - For humans this could be cooked, once, twice, soaked in cold or hot water, raw or any number of methods. For rabbits, it is almost in every instance raw.
Once you know what you have then you can check lists. It can still be confusing. There are lots of myths and tales out there to to make thing inaccurate. There is not much real information about rabbits. Mind that rabbits are hind gut creatures like horses and goats. It is good to cross reference their edible food lists too. LOTS of info is out there for horses. When doing research the word "fodder" is a useful search term. "
Erigeron Strigosos as fodder" was a pretty informative search.
The fleabane in know is also called mares tail -
Conyza Canadensis. It is also a member of the aster family and has a similar flower. BUT, the flowers grow in clusters (
I ) and the plant, when flowering (
T ) is very tall perhaps 3 feet. It is not good for horses since it causes severe runny nose. I don't care for the smell. The smell is irritating just inches from my face.
The good thing about the list we have here (linked above) is that we have all researched the plants fairly well AND they are empirically tested by us.
@MaggieJ keeps a good eye on the thread and generally keeps it up to date. So if you determine that your
Erigeron plant is good, you should post in that thread too.
