Here on the blueberry farm we have a collection of Rhododendrons. Getting ready to plant the rhododendron Teddy Bear we were struck by the indumentum on the underside of the leaves. Indumentum is the fuzzy brown/orange hairs shown in the picture.

Even when planted, Teddy Bear proudly displays it’s indumentum.
