Hello David. I have been disappointed with my SPs this year - the first flush of flowers was pretty good but it's been downhill all the way since then. I have to put it down to such poor weather, especially here in the West Country. Light levels have been low, sunlight has been in poor supply with exception of the odd few days here and there, and my plants are now way beyond their best. Out with them, and looking forward to next year!
I bought seed from a local(ish) specialist, but the results weren't a patch on Eagle seeds. Even allowing for the poor weather, I have to agree with you regarding the quality seed (and no, I'm not advertising, just passing on personal experience).
Oh, well - it's the looking forward that keeps us gardeners young (I think
). And who knows, by this time next year, I may have managed to complete the move that we had hoped would have been completed by now! So - autumn sowing it is - and fingers crossed for a better summer next year!
