seeds. (Bournes Green SS2)

anyone have dried or ready to dry flower heads for a mixed widld area i'd like to sow?? i have some sweetpea sedds froma friend but i'd love things likesweet williams, marigolds and other bright smelly butterfly and bee attracting flowers. any size and any sunshine to shaded areas i have to grow them in. i dont mind drying them out so heads of flowrs will be ok as well.
