Hoheria populnea
In the corner of the QMM garden is a columnar tree full of lightly scented musty white flowers. Awash with flowers this Hoheria populnea is a deciduous member of the genus, native to South Island New Zealand. A plant to be appreciated in a season of decaying herbaceous growth and wet swirling leaves caught in corners of the garden.

This isn’t H. lyallii. Foliage and flowers are wrong. If this was flowering 24th Nov, flowering time is way off too. I am confident you’ll find it to be H. populnea.
