[brushhippie]

Growing up around it Ive gotten the berries on me many times and while it isnt a vibrant color is will stay...the only thing that stains worse I know of is cow poo...so thatsll get ya dull purple and pale green...if thats the color you want..

You can also use different substances as a mordant to achieve different tones and colors, i.e. salt, alum, metal filings ( steel wool) borax powder, vinegar (white or apple cider). 

I too love playing around with natural dyes, iron oxide powder, leaves,  onion skins, sumac, grass, various flowers, madder root, the list goes on and on.... Just be sure to test it on a small piece of scrap cloth, or just buy a cheap skein of white yarn ( which is what I do) to make up several low cost samples.

I love coffee, tea, walnut hulls as much as the next guy, but there are so many more colors available that it's really quite overwhelming. 

I'm certainly no expert, I just have tinkered around with it for a long time now, and it really is fascinating to me. 

Poke berries are one I have not used, gonna have to check those out.

as to the toxicity of the plant , this should be of some help :The poisonous principles are found in highest concentrations in the rootstock, leaves, and stems while only small amounts are in the ripe fruits.[13] The plant generally gets more toxic with maturity with the exception of the berries which are more toxic while still green.[
