Pacific Rose™ is a high-quality dessert apple derived from Gala and Splendor, which has become available in supermarkets from around 2005. Visually it mostly resembles Splendor. It is primarily an apple for eating fresh.
Pacific Rose™ is the marketing name, the actual variety name is Scirose - it is part of the same breeding programme from ENZA that brought us Jazz (cultivar name: Scifresh). The marketing name seems to nicely fit the apple.
