My son is getting married on 29th September and I'd like to get them a plant to mark the occasion. What would you recommend? It would ideally be good for a pot, as they currently only have grass and gravel, be in flower at the time of the wedding and have interest for the rest of the year. I'll probably have to order it mail order as I won't be able to carry it on the train. And if possible something appropriately named, but that's not such a priority.Hope that's not asking too much!
