I bought my large Blue Peter decades ago and love this 8-10 foot shrub even when it is not blooming; the leaves are lovely. This large rhodie rarely complains. “In the nautical world, the Blue Peter is the nickname for the "Papa" (P) signal flag—a blue flag with a white square in the center. When flown in port, it signifies that the vessel is ready to sail, and all crew and passengers should report on board, as the vessel is about to proceed to sea.” Years ago I talked to a couple motoring in a beautiful old-fashioned wooden boat named Blue Peter. They explained the nautical term to me and I told them about my beautiful Blue Peter shrub. This is a wonderful plant to plant.
