These are growing in a London garden of a large Victorian house. Hardy and prolific. Large green leaves with red veins, 2 metres height and 1.5m width approx. Flowers late August onward, small individual flowers in large bunches.
Clerodendrum bungei. I like those,
I'd always understood they were not completely hardy which put me off getting some.
Thanks for the ID. My friend says they seed freely, get no care at all and flourish and flower. He owns a flat in the Victorian house so is not responsible for the garden. He also has one plant,, transplanted into his own garden, which has been there for several years. His garden is small and fairly sheltered by hedges. He brought me one which I have in a pot ATM. It's grown rapidly so far in a fairly shady spot with midday sunshine. I will have to move it somewhere else shortly and could not find out what it is. The London ones are on clay, of course, over chalk Here it is chalk with whatever I can cover it with. I can investigate further now so many thanks
