Re: revised inquiry re: coltsfoot

Yes, it is a Petasites or coltsfoot (and possibly Petasites frigidus) -- is this from a native plants nursery or wild collected seed?

 

Not Coltsfoot (Tussilago); it is one of the butterburs (Petasites).

 

Not in this part of the world. Colt's-foot is the name used here.

 

thanks all for replying

trees, shrubs and flowers of bc by cp lyons

i thought it was petasites speciosa, also he called it butterbur but i needed confirmation which you have now supplied

the p.frigida i now see here in the book
it is coast to rockies/alpine variety

so it is then not the medicinal variety i hoped for

i found it growing profusely by a waterfall inland but somewhat near the chillwack river

does it have any special properties that you may know of?

thanks very much again
