Your photo looks like what is left of a Dracaena marginata, a species that can grow to 10 feet (like yours) and is very tolerant of a range of conditions, meaning it is widely sold. Plants traveling by trailer should be wrapped with plastic (or for deciduous plants, moved in dormancy). Otherwise, wind dehydrates the leaves. Fortunately, dracaenas tolerate pruning well, so that works in your favor. Cut off all the totally withered and dead leaves at the trunk and prune back to healthy buds. Place the plant in bright, but not direct, sunlight. Water enough to keep the potting soil thoroughly moist, yet allow the top inch of soil to dry between waterings. Don't let it stand in water. Fertilize the plant during the active growth period, which generally means spring through fall. After it has recovered, you can prune it periodically to avoid a lanky, bare look.
