CLERODENDRUM SPECIES
My intuitive colleagues is probably right. This is like a dowdy or ugly stepsister version of the Clerodendrum myricoides 'Ugandense' (common name: Butterfly Bush; Family: Verbenaceae) which I totally love. Can you imagine it?
Anyway, the flower of this simple, ordinary looking plant is just pure white but it seems like a highly fertile plant with all the green berries on it.
