I need a nice specimen street side tree and really have my heart set on albizia Summer Chocolate. Have my vendor picked out but don't want to order until I get some feedback. I'm wanting to plant it next to the curb right next to the driveway that leads to our back yard.. I never trust the catalogs or websites descriptions of growth and eventual maturity so I'm wondering if someone is growing this tree in simular area and can give me the real scoop on this tree. Condition are full sun an slooping lawn that stays pretty dry during summer months because no matter how I position the sprinklers it's an odd area and I never seem to be able to hit that area for a good watering...unless I want to water the street.Any warnings on it's roots and spetic systems?
