Bilji...glad to hear you enjoyed this thread.
Although I do appreciate that sometimes needs must, I've never been keen on growing SPs in containers. They are so deep rooted, they are best grown in deep cultivated ground in the open if possible.
Of course, autumn sown plants will stop flowering ahead of those sown the spring anyway....a good plan is the hedge your bets by sowing seed at both times.
