I'll be starting my Datura, Cleomes & chillies off in the new year.
Also some Aserina, as I haven't done these to grow in the same season before. I've only started them off the summer before & overwintered them.

Thanks. I shall research Aserina and cleomes and see if I can find seed. My little secret is a place in southern Spain.tiny but with a sunny terrace. If I have potatoes left after a stay I plant them in the tubs. freesias do very well there. I would like to start something off there and bring it back to plant a few months later in Wales. thanks again

A general "rule of thumb" is,I believe, sow the very small seed first i.e. Jan/Feb and so on..

Thank you that makes sense. I have bought asarina seed on ebay . Cant wait to get started. I shall sow some here and some in Spain Unfortunately my greenhouse is more frame than glass. so it will be windowsill for me, or propagator in garage.
