Common Ragwort or Jacobaea vulgaris and related species.

The Common Ragwort is a mini-habitat for wildlife and seen growing here in a Cornish Hedge! (by M. Summers)

In my previous post all about the classification of the Asteraceae I mentioned Ragwort which used to be in the genus Senecio with 20 species but some have now been split off into the genus Jacobaea.

Today we talk about Senecio and Jacobaea or the Groundsels and Ragworts and their uses. Some of the neophytes can be grown as a garden plant and indeed may have escaped into the wild from your garden……

But the family of Asteraceae is highly evolved to home many insects and supports a rich biodiversity, so is very useful to them!

I use colour coding for easy reading! Blue background is general interesting info (although I hope you find it all interesting!!). Green is about all the uses except for medicinal uses or if there is a warning ( and in this case negative propaganda) in which case I use a pink background.
