This seemed like an easy one to try.
If I'm being honest, I wouldn't rush to try these again with the same method. If I start experimenting with other mordants and dips then maybe, but the result was similar to nettle, but somehow not quite as rich. Although, as I look at it now sitting beside other colours it seems to be improved, so who knows!
gathered 784g fresh dock leaves
some rhubarb leaves from the garden to act as mordant
dyebath: 50g of roughly chopped fresh dock leaves and 30g of rhubarb leaves, left to boil for one hour
25g of unmordanted, soaked wool yarn
