Hi there! I live in Sunnyvale, CA and am needing to select plants for my side yard. I'm a tad overwhelmed since I know very little. I feel like I want some moderate height privacy, don't want to destroy hardscape or fence or neighbor's yard. I'd love it to fill in, not be boring and pretty to look at. Any suggestions on plants and quantities from the wise one's out there? It's ~30-40 feet long and ~3 feet with a "drip" sprinkler head in the center of each fence panel. Ty!!
