Question: is seaberry the same as sea buckthorn?
Answer: Hippophae is the genus of sea buckthorns, deciduous shrubs in the family Elaeagnaceae. The name sea buckthorn may be hyphenated to avoid confusion with the unrelated true buckthorns (Rhamnus, family Rhamnaceae). It is also referred to as sandthorn, sallowthorn, or seaberry.
