I've sown Slipper Flower (Calceolaria mexicana), but I haven't started my salpiglossis seeds yet. I think I need to try to time those just right since I have no light setup.
I've also sown several impatiens species, a few lavatera, Pink Flowered Tweedia (Oxypetalum solanoides), Cleome lutea, Petunia (Petunia grandiflora 'Avalanche Blue Star'), Chinese Foxglove (Rehmannia elata), Mignonette (Reseda odorata), Yellow Eyed Grass (Sisyrinchium striatum), Texas Tarragon (Tagetes lucida), Chinese Cucumber (Trichosanthes kirilowii) and of course lots of different Snapdragons and Pansies.
I also have a great many yet to sow...
...and there's still a month left to wait before I'll start sowing peppers and tomatoes!
