Magnolia grandiflora is reckoned to be the most magnificent broad-leaved plant that can be grown outside in Britain.  Here we have a lovely young cultivar, M. g. ‘Goliath’, in the magnolia triangle above the Rose Garden.  The glossy undulated leaves are a perfect foil for the beautiful pure white flowers which have a delicious lemony scent.  Each flower carries male and female parts which reach maturity at different times, and the shedding of the stigma can be seen before the pollen part matures.
