Has anyone any idea what this plant is? It's about 30cm tall and I have another which is just one stalk about 80cm tall with big leaves at equal spacing. The taller one hasn't flowered but has grown very fast.
Looks like 'Corallina de Lucerne.'
Cane-type begonias are wonderful, easy to grow and winter over. I have several types and they keep getting bigger and bigger each year. But I keep mine outdoors in summer.
