Buddleja saligna has long narrow dark green leaves, the underside covered with pale hairs. The white flowers are borne from midsummer. Not hardly in the UK best grown in a glasshouse.
When describing Buddleja saligna to visitors at the nursery I call it the “olive” Buddleja as with its long narrow dark green leaves when not in flower it looks like Olea europaea.
Named and described in 1909 by German botanist and taxonomist Carl Ludwig Willdenow.
B. saligna grows wild in South Africa, Natal, Orange Free State, Transvaal and north to Zimbabwe. Habitats range from mixed scrub, forest margins and coastal thickets to edges of wooded valleys to an altitude of 2000m.
