Last year a a friend gave us a begonia in a plastic hanging basket. Not having anywhere to hang it I put it in a tall pot on a ledge.
After a worrying dormant winter, where there was no sign of the plant in the pot at all, it reappeared and is growing beautifully on our front verandah.
Half wants to grow upwards and half wants to hang down.
But it is pretty even if directionally challenged.
