Murphyette,
If you keep the area around the
plant open and compost like material around the base....
It will reseed for you too!
I don't believe the actual
plant itself comes back, it relies on the
seeds to create more of it's self.
I am a composter and I use leave mould, so it reseeds for me pretty good.
I'm not sure about when large chunck's of pine bark or the like are used for mulch under it!
It seems the finer consistancy used around it~ the more likely hood of it's
seeds' survival.
But experiment, let some fall naturally around, collect some
seed and put in some dirt filled pots and over winter outside, and save some in a cool area of your house inside a mailing envelope.
I don't know enough about the
seed to know how to treat the
seed for next season's use.
(*like needing to have cold or freezing temps to activate it or if it can just be sprinkled on the ground or covered,
seeds have different
growing requirements..)
I usually let mother nature do my
seed saving???
