Can anybody help me identify this plant from the picture posted? It has waxy rounded leaves and is very easy to look after. From the picture you'll see it is flowering in late Summer / Autumn UK.
Sorry to revive an old post, but:
It's not a clivia, it's a Heamanthus albiflos (elephant's ear / paintbrush plant). Close relative from the Amaryllis family, but not the same. Main differences: Clivias have clusters of bell-shaped blossoms, usually orage(-ish), the leaves are thinner, longer and often darker. OP found the correct answer himself.
(Your specimen might appreciate a bit more light, if possible, as it appears a bit lanky.)
