Additional comments: Lady's slippers is an interesting, semi-succulent accent shrub for small and narrow landscape borders. It's quite a nice accent shrub that features the landscape elements of texture and line that contrast well when planted alongside finer textured and more rounded shrubs. However, it can become quite the mess as it gets older....all entangled up, scruffy, sprawling and rambling. Older specimens kinda make me say, "Meh!"

Stems contain a white, milky latex that is 6% to 10% rubber.
