I am new to gardening. We recently ripped out some big overgrown bushes from our front yard and would like to replace it with something that grows no taller than 3'-4' tall as we would like to keep our nice window view. I am totally clueless and have been trying to research online but it's very difficult. We have a 9x9 space and I would like to fill it with some nice, easy to take care of plants that stay green all year and produce flowers/edible fruit(if possible). Any suggestions would be greatly appreciated!
