Thank you Rosa for your sensible answer

how do I get a seed catalogue ?
I need to fill up front rockery (removing some rocks and putting in clumps of colour) instead of buying all new plants though I'd 'plant' some seeds too (not in ground into pots, summer bedding or things that I can grow on, pot on , will come up again) , as its so wet there thought seeds may end up cheaper than replacing plants if they don't work
Hope you don't change avatar to a thong Geoff with your new name
