The hopseed bush is suppose to get about 12 foot tall and wide out here in
the Phoenix area. I have them at 6 feet apart, so if I plant them at 3 feet
apart, will they be OK? They are for my backyard with a black iron fence, so
I just want to block the neighbors out, but not at the cost of my plants
dieing. I figure one purple and one green at 3 feet apart across my 55 foot
backyard fence. What do you think?
