An indispensible annual

I'm a latecomer to this thread, but many lovely things- I like the idea of native and native/wild-looking annuals that gently seed themselves around the garden, and most of those shown here are lovely! Love the red poppies, Mark's bluecurls and the ex-Cleome, and the Layia is very nice - as well as all of John's desert annuals- I've looked at a number on Alplains' lists, but have been waiting to have a more established set of beds before getting any...
I don't think I currently have any annuals, but some biennials (I think many native annuals are biennials in this short summer climate)- Geranium bicknellii, Corydalis aurea ( I think this will soon be in every bed I have, but its easy to remove unwanted plants) and working on establishing its cousin Capnoides sempervirens, Androsace septentrionalis, and some non-native Violas here and there..

For those of you who have frequented SRGC forum, you may remember Simon in Bulgaria had some very sweet little annuals around the garden..

I'm still trying to envision Jane's exotic weed free world! (not to mention bug-free!) I wouldn't mind much if I only had to pull out native seedlings (the native plants are all around, so hardly surprising) even though it would still be extensive work, but add the agriculture related weeds and it is pretty steady work, with no chance of every getting any kind of final result- my aim is control, not elimination: I don't even worry that much about bits of root, of course I pull out as much as I can, but getting rid of every bit of weed root wouldn't make that much difference, they will be back via seed within weeks if not days,..
