This is a very handy reference for seed saving and swapping, covering all the basics of why seed saving is important and listing many organizations involved with heritage and heirloom seed saving around the world. The book itself is beautiful, with lovely page spreads that are very nice to look at. The plant directory has some very useful features and some things that just make me wonder...One of the things that I really like about the directory is that the plant family that each vegetable or herb belongs to is included. This partly just caters to the plant geek in me, but I really enjoy knowing that information. The special requirements information is also wonderful, detailing the steps that need to be taken in order to harvest pure seeds. The organization of the directory leaves somewhat to be desired from my view, plants are separated into the groupings of 'vegetable' 'herb' 'flower' and 'salad vegetables' which seems a little odd to my brain. Further, within the groupings the plants are not organized alphabetically, leaving you to flip through pages randomly or check the index for a particular plant. Finally, although it claims to have the 'most common' species listed in the directory there are some odd omissions, like including runner beans, but not regular beans, rutabagas but not radishes...
