Please define the growing information when it pertains to the amount of sun that a shrub should get. The planting Tags say partial sun, moderate sum, some shade, full sun. Just how may hours of sun is needed to fulfill these requirements. Can you list 'um all?

It's difficult to define, but here are the generally accepted rules: Full sunshine means 8 or more hours of sun. Roses, for instance need full sun. Partial sun would mean either 4 hours of morning sun OR 4 hours of afternoon sunshine. Moderate sun equates to morning sun because it is not as intense as afternoon sun. Some shade fits this same pattern - morning sun and afternoon shade. Each plant is different in its requirements for sunshine and its adaptability to growing conditions. If a plant tag says full sun to partial shade, for instance, it means that shrub will grow in full sun but adapt to partly shady conditions, as well. Hope this clarifies things for you!
