Oxalis, begonia and lobelia window box

Versatile needn’t mean humdrum, as this window box collection proves. Begonia sutherlandii is classier than its hanging-basket cousins, with its tangerine flowers and matching veining to the leaves, while the contrasting leaves of the purple shamrock close like resting butterflies at dusk and open up in sunshine, throwing out lilac flowers on delicate wiry stems.

Place the container on a window ledge in part shade or use to grace a cool flight of steps. Remove the yellow lysimachia flowers when they appear – if you dislike the colour clash – and water well when it’s warm.
