That was quick -they only went in the post box on Thursday afternoon! I had to ask Mark for his mail address and it came through just as I was shutting my work computer down for the New Year Holiday ( refering to another thread, Monday & Tuesday are public holidays so I took Friday off as well after finishing early on Thursday- public servant speak).
My responses to Mark's questions are :-
1) Sow now
2)Each species to one pot, although with a dozen seeds you might make it two
3)JI seed compost & equal grit as I use this for almost everything
4)Rapid germination, some should appear next spring/summer
Good luck
