Hey there! Did you see my post on Growing from Seed - not much response there maybe better luck here.
I scattered:

Mexican Hat
Platycodon
4:00
Nicotiana
Impatiens Balsam
Jewel Weed
Gaillardia Goblin
Various Poppies

Hope this works! First year doing this so . . .

I too often scatter seeds of things I want to grow for the next summer now. Some are things I might buy - others are my own seeds from my gardens.

They include:

echinacea
balsam impatiens
cosmos - seed heads
morning glory - careful these can be invaisive
valarian
persicaria
phlox - but, some don't come true to parent
asters
penstemon
pulmonaria - they might not bloom the first year

Good luck and have fun...Beverly

Thanks for answering my question, too...I've planted mostly annuals for the three yrs i've been bit by the garden bug and wish to get into some perenials...Thanks All
