Simon Fraser is a small sprawling shrub with glossy leaves and salmon pink blooms. A young bush is apt to produce single blooms but as the plant gets older, more petals form to a semi-double. The plant is prone to mildew and blackspot. George Vancouver is a semi-double with decorative dark red blooms that fade to pink with age. It repeats well.
Growth habits vary from a compact shrub to having long arching branches.
Lambert Closse is a small bush. The coral pink blooms fade to light pink and are very double. The blooms have quilled petals and some fragrance. They have the best form of any of the Explorer series and repeats very well. Royal Edward is a very low spreading, hardy bush that can be used as ground cover.
