Rhododendron hodgsonii (native to Bhutan, India and Nepal), with its large textured leaves, is beautiful in winter. It is near the monarch birch in bed 123. You can see the silvery brown felty undersides (indumentum) of its leaves higher up. However, in spring, it really struts its stuff with large, dark pink blooms. It was planted in 2012. Joseph Hooker named it after Brian Hodgson.
