lost the overwinter ones, these were planted 12/2, coming on really strongly now, excuse the crush ;D
I didn't bother with overwintering any this year....so mine are only just in their pots! ;D
I forgot to sow some for over wintering, and like you sowed in Feb and they are coming on a treat as well. I just love sweat peas up on the plot :) I'm going to use a shirl wilco arch to grow them up ;D
Same as Deb, only just sown mine too.
