I scattered seeds last year from the little blue and white winkies and lo and behold, they are everywhere. I have seeds I collected from the tall fellows. Not sure if I should bother to scatter those as I have preened the beds not that it seems to have stopped the chickweed. I guess I need to do a surface cultivation then reapply. I did put some of the seed in six paks to try to grow them that way. Haven't had much success with that method. Did manage to get some Golden Jubilee from saved seeds and some campanula.
