Eileen,
It depends on your style of gardening how to keep them under control....
If you like
plants that reseed, for other parts of your garden, or for trading with people,
then leave the
seeds on and either let them be and
spring up around in the garden and move them to different places, or cut the
seed heads off when they are done drying and save them in a mailing envelope or brown paper bag *go to the
seed department and ask, other's may have different ways of saving them* Or just after they are done flowering, cut them back a bit, and they should reflower for you. And
seeds will produce on the last set of
flowers around fall time.
