Single form. Pure white, but may open with lavender blush which quickly fades. Medium large flowers carried on upright stems. Filaments, sheath and stigmas are violet-purple. Petals may have small flares. Leaves are often large and leaflets long. Historically propagated in China for medicinal purposes (root bark). Derived from P. ostii and is representative of the species as the plant no longer occurs in nature. Often sold as ‘Phoenix White’. Most clones are highly fertile and produce many seeds per carpel. Not tolerant of wet conditions, but extremely vigorous when conditions are correct.
