Soon I'll be moving, and while I will take a few of my smaller Japanese maples etc. and put them in part of the front yard, I am thinking I want most of my yard to be populated by critter-friendly plants--ones that provide food, nesting spots/shelter for birds and beasts. Currently the large back yard is rather barren, with pines at the back and toward the side, so I have a decent amount of open space to chip away at. Depending on where I plant, and the things I put in eventually providing shade, most of this will be in sun or partial sun. I don't think that area is arid or particularly moist. I am in the Boston area and like to allow for all contingencies, so I generally plant things that are for zone 4. Fairly carefree but not horribly invasive would be pluses.
I am starting a list of possible plants but wonder whether folks here have some recommendations. Sites and books would also be most welcome. Thanks!
