These have finished flowering for this year and I have removed the seedheads. I have Nigella (a mix of blue and white), Marigold (orange) and Lychnis(bright pink) . Also a few Cardoon which are huge fluffy seedheads. You can scatter the seeds in autumn or next Spring and they will flower next year. Look good in a natural planting area or can be mixed in large pots.
Pick up from E15 4JW evenings or next weekend. Say which you want and when you can collect when replying.
