small tree that will do well in 1/2 barrel with SW exposure
I want to plant 2 small, ornamental deciduous shade trees (or large shrubs) on both sides of a driveway to give a symmetrical appearance. One neighbor completely opposes putting any tree into the ground, so I'll need to use a 1/2 wine barrel on one side.
Can anyone recommend a tree that'll fit the following critieria:
-drought tolerant (able to live in a barrel with water twice a week at the most)
-small and ornamental shrub or tree
-non-invasive roots (because the neighbor on the other side will approve of an in-ground planting....though I could put them both in barrels for symmetry)
-able to withstand hot summers with SouthWestern exposure
USDA zone 9/sunset zone 14ish
Of course I'd give preference to anything with fragrance or beauty, but I don't want desires to prevent me from finding something that would happily grow in these conditions. :)
any suggestions appreciated!
