I photographed this South African bush, around 7 foot tall with masses of spherical white flowers, around 1cm across, on stems with sparse, small spiky leaves appressed to them in the Mediterranean biome dome at the Eden project UK. I couldn't find an ID label but am pretty sure it's a Berzelia sp. perhaps B lanuginosa, the Buttonbush. Brunia species are very similar but seem to have a denser arrangement of leaves on the stems, and the overall growth form looks more like Berzelia to me, but does anyone know the genus and even species for sure?
