Considering the Oxlip (Primula elatior) is limited to the border area of Suffolk, Essex and Cambridgeshire, the answer is a simple “no”.
Is that an Oxlip?

This plant, high on the southern slopes of Home Wood, is a False Oxlip (Primula veris x vulgaris), a naturally occurring hybrid between Primrose and Cowslip. As it has flowers right round the stem, this false Oxlip is easy to tell apart from the true Oxlip, whose flowers all point in one direction.
While there are lots of Primroses nearby, the only puzzle is where did the Cowslip part come from? As the nearest I know is 1/2 a mile away … time to look more closely.
High up on the Northern slopes of the lower part of Ashwick Grove is Raven’s Rock. As it is set back, above the track, it is much less known than Clare’s Rock further up the valley. I climbed up to take photos and discovered the whole mossy slope below, it is actually a scree slope of large rocks all hidden by Ferns and Mosses. It’s a hard climb, but the views at the top were worth it.
