Arid / Drought Resistant Privacy Plant
We have a small portion of land where we'd like to plant something to act as a privacy screen. This area is quite far from the nearest water outlet / hose, so I'm looking for something that can tolerate drought-like conditions.
FWIW, we have Italian Cypress here that do great, with nothing but the rain water they receive from November to May. Those however get too tall for this location. We need something that will get at least 6' tall, but no more 15 to 18 feet.
The soil is very hard clay. In the more severe weather years, we see 100 degree deltas (18 in the winter, to 118 in the summer).
Any ideas? Looks like the bottle brush might be one possibly, but I'm not sure. Thank you.
