The single form, Rosa banksiae normalis, is believed to be the original wild form. More commonly grown now are the double varieties. R. banksiae banksiae was the first to be botanically described, introduced from Canton, China in 1807 by William Kerr to Kew Gardens, England and named after the wife of Sir Joseph Banks (at that time the director of Kew). It is unclear if this is a hybrid cultivar, as both double and single forms are found in the wilds of China. The white Lady Banks' rose was once the most common in cultivation, but largely became replaced by the double yellow (subspecies lutea).

Additional comments: Lady Banks' rose is an excellent accent climbing rose for Phoenix. It is best grown where its enthusiastic vigor need not be restrained. Grow it as a naturalized plant or over a sturdy (very sturdy) structure. The Guinness Book of World Records identifies 'The Tombstone', a double white Lady Banks', as the single largest rose plant in the world. Located near its namesake, Tombstone, Arizona, it covers 8,000 square feet and was planted in 1855 by a homesick bride.
