Ecoprint with cotton: not just black

We've seen many black prints on fabric now, all resulting from the iron (II) sulphate.

But there are some other possibilites as well. A few leaves are printing color on the surface during this boiling process. Especially when alum is used as a pre-mordant.

A specific type of garden geranium is printing green:

American indigo is printing a soft green (and such a lovely shape)

Blackberry sometimes turns out yellowgreen (like birch leafs too)

Eucalyptus is printing an orange red:

And recently I discovered Aquilegia is printing orange/red

So, what are your finds?

NB. This post from Threadborne is an excellent overview of colours obtainable by eco print:
