Blimey Hells you're a glutton for punishment, what period did you cover for your level 2. I'm just about to sit and do my Georgian assignment (which has to be in tomorow). We have to touch on baroque, rococo and neoclassical. Have found quite a lot of info out there on Georgians, don't really know about the others although I imagine Victorian wouldn't be too hard to find. Good book to get hold of Flora Domestica covers all the periods and the flowers.

Good luck.
