Zantedeschia 'Snow White' (Arum Lily) – Hardy Perennial (3L Pot)

The white arum lily carries sculpted, trumpet shaped white spathes above bold arrow shaped leaves, from late spring into summer.

'Snow White' is a form of Zantedeschia aethiopica, the hardy white arum, and reaches 60 to 90cm tall by 30 to 45cm across. The shape of the flowers and the weight of the foliage give it real presence, so it works as a focal point rather than as a filler, and the blooms last well when cut.

It wants moist, humus rich soil in sun or partial shade, and it is equally at home in a damp border, beside a pond or as a marginal in shallow water. It also grows well in a large container. Water it through the growing season and do not let it dry out. Left in place it returns each year and forms steadily bigger clumps.

Mulch over the crown in autumn to see it through the cold. It is hardy in most of Britain, though a hard winter in a cold inland or northern garden can damage it. All parts are harmful if eaten and the sap can irritate skin.
