This is one of our mature shrubs, vigorous and evergreen, with deeply veined rather leathery leaves, and quite big cymes of creamy white flowers. Unfortunately the flowers are very dull until they finally open, and once they have, they last only a few days before turning a dull light brown. The flowers are apparently followed by ovoid red frutis which ripen top glossy black, but I have never noticed these. So all in all, I find this the most disappointing of the viburnums we have.
In its favour is the fact that it grows in rich, moist, and very acidic soils, and tolerates wet soils. It needs shelter from cold drying winds, and does well in shade. Possibly the floweirng would be better if it were in more sun. The leaves droop during extended cold or dry periods. There’s quite a catalogue of pests and diseases to which it is allegedly prone, but doesn’t seem to be affected by any of them with us.
