I have both of Adrian Slack's books - both are very good. "Carnivorous Plants"
gives good descriptions of the more common species and fairly detailed growing
instructions. "Insect-Eating Plants & How to Grow Them" gives much more brief
descriptions and instructions, but makes up for it by covering many species
and giving lots of color photographs.
>p.s. I am thinking about building a bog garden in the backyard,
> has anyone tried that?
We built an island-type bog in a small 3x3' (or so) fibreglass "tub" (which
was actually a mould used in the construction of the "new" Parliment House
in Canberra! One of our uncles picked up a few for plant tubs.) The plants
grow pretty well in our climate, but perhaps the best advice I could give is
that you must not underestimate the amount of peat moss it takes to fill a
bog! Also, it would be better to make a much larger (but fairly shallow - say
12" deep) rather than a small, deep one like ours - it will look much more
impressive. Adrian Slack details a few designs and construction methods in
his second book (IEP&HTGT).
Good Luck!
