Ralph Moore wrote in the Winter/Spring 2002 Issue of MINIRAMA (available by subscription through Sequoia Nursery): A new hybrid musk, STW-1 ('Wiltherese'), 'Sister Therese' ('Soeur Therese') x 'Wilhelm' ('Skyrocket'). A vigorous arching shrub (or climber to eight feet). Abundant large foliage, free all season bloom, clusters or sprays from 5 to 20. Long pointed bud, semi-double, three-inch flower, pink to red in color -- similar to 'Charlotte Armstrong'. Orange hips provde winter interest. Other (amateur) breeders may wish to try this rose. It is a colorful shrub in the garden.
