What is the common name for Rhus typhina 'Laciniata'?

The common name for Rhus typhina 'Laciniata' is indeed the Cut-leaf Staghorn Sumac. This name is derived from the unique and distinctive leaf structure of the cultivar, which features finely dissected, or "cut," leaves that give it an elegant appearance compared to the typical broader leaves of the species. The term "Staghorn" comes from the plant's branching structure and the form of its fruit, which resembles the antlers of a stag.

The other names provided do not correspond to Rhus typhina 'Laciniata'. Coral Bark Maple typically refers to Acer palmatum 'Sango Kaku,' known for its striking coral-colored bark. Golden Ash refers to the species Fraxinus pennsylvanica with golden fall colors, while the Weeping Willow is Salix babylonica, recognized for its long, trailing branches. Each of these plants has distinct characteristics and therefore does not relate to the cut-leaf staghorn sumac. Understanding the unique features of plants helps in identifying them correctly by their common names.
