Good call, "Euphorb!" It is Epigaea repens, Trailing Arbutus. At home on acid slopes, this tiny native shrub stays green all winter and flowers in April and May. The flowers emit a very strong, very attractive spicy fragrance that can be detected from a distance. Look for it on the steepest slopes, especially cool north and east-facing ones where mosses are abundant. A photo of this plant in flower is posted below.
