Dye It

I have been wanting to learn to dye my own wool to achieve the colors I want, especially greens.  A friend gave me a dyeing lesson last fall.  We used a plant from my garden to produce this color:

                                    Dyed roving and felt

What plant might it be?  Eucalyptus!  Some eucalyptus (you know, that gray-green tree) are only

marginally hardy where I live, but I love them and keep planting them.  The last one came down in a

storm, and I saved the leaves for a friend who is very skilled in natural dyes.  She boiled the leaves 

(very aromatic) outdoors, let the dye pot sit overnight, boiled it again, added the wool and soaked it 

until we had achieved the intense color above. Who'd a thunk it?
