Re: Astilbe seeding was: Shade problems

I'll second that, Gary.  I left some self-sown A. taquetii seedlings in the
cracks in flagstone paving 'cause I thought they looked cute.  Never again!
 Had to lift the pavers to dig them up and then got the joyous task of
re-setting the flagstones.....and have never gotten them quite even again.

For reasons I do not understand, Aruncus did the same thing -- and these
are plants that have never put a seedling in the border anywhere near the
parent plants in the nearly 15 years they've lived there, but selected the
paving a good 4 feet + (120 cm+) away!  Aruncus get a little hard to walk
over :-)
