I'm in zone 5, about latitude 42 N, in a wet climate (40" snow, 40" rain). We have a two story house with a fair number of windows on the south side, which is great in the winter ... but it tends to overheat in the summer. I'd like to shade the southern side. Unfortunately we only have 2-4' of space between the southern side of the house and the driveway, and the driveway extends to the property line further south. So there isn't room for planting deciduous trees. Awnings might work but would be tricky (we have angled bay windows, and the second floor windows end just below the narrow eaves, so there isn't really anywhere to put awnings there). We can't excavate to put arbor / pergola foundations in next to the house, because the gas line runs between the house and the driveway.
So... I wondered if perhaps I could plant bamboo in containers (to contain the rhizomes, and to allow for moving if the gas line needs to be serviced) and chop them down every fall. Would that work? What types of bamboo might work for my conditions? Are there other tall, fast-growing plants that would work? I tried giant sunflowers (supposed to get 12'+ tall) but in this cold wet spring they took a long time to get going and are only about 3' tall so far. I'm leery of vines because I don't want moisture against the house, and don't want them finding their way under the siding.
