If you want a skinny tree, take a look at Parkland Pillar Birch, 40’ tall x 6-7’. It’s perfect for narrow spaces. For an evergreen, Chapel View Japanese Cedar, Sky High Juniper and Technito Arborvitae will all do well. If you want flowers, Sparkling Sangria Fringe Flower, crape myrtles and hibiscus are good choices.
