Hi, we live on Long Island NY, zone 7. we have an awesome little area with very little plants. My husband and I are not good at up keeping plants so we wan to make this look nice and make sure it's easy to maintain. We're looking for perennial plants. Mixture of tall & short. Perennial flowers too if they stay in bloom long enough. I'm open to putting in a small tree if it's easy to care for. We have decent sun and inground mister sprinklers in that area. I'd like to post a picture but the site won't let me. I'd reallllly appreciate any help you have to offer. Please help us! We were at the nursery for hours yesterday and were so overwhelmed, we just left.
