Need some advice on specific tufts.

[WillieB]

First one is probably the easiest I bought a fairly large sheet of 'WustenbXXX' - can't read the rest of it- and it represent some dry looking grass. Perfect for my Indian Mutiny figures but I can't for the life remember where I bought it and I'm slowly running out.  Any ideas?

next one may be somewhat harder. Is there a tuft that could represent purplish heather? I intend to use these for my dark Age Scots and Picts.
Any help greatly appreciated!

For heather, maybe the purple flower + burnt umber foliage of these very nice (local-ish to me) flowering tufts?

Gamers Grass are very good. They have a wide variety of colours and types.

Here are some purple flowers that could represent heather.

Not sure where you are located, but I used some Leadbear's Tufts (Australia) for heather with my Scots for the 100YW. Not sure they are very obvious in these pictures, but try:
