Young leaves are brownish red and bolt upright. It is also possible that they are instead infected with the fungal infection called Cowberry Redleaf, where the upper surface is red and the lower covered in a white powder bearing spores (although this isn't evident in the photos), and which also infects a number of other members of the Heather Family.
