Hi Pete

I use Chase Organics (the HDRA cat) myself for most things.

These are some others which I've had recommended to me, or used occasionally.

Terre de Semences
Seeds by Size
Future Foods - for all sorts of unusual stuff!
Thomas Etty

Have fun - a real pleasure as the evenings draw in; get the paper copies of the catalogues, and browse, and dream!

All best - Gavin
