Description
Arum hygrophilum is an unusual and distinctive species with probably the most beautiful flower in the genus. Strongly lobed, up to 2 feet (60 cm) long leaves appear early in the fall, followed by the narrow, creamy inflorescence by early spring, the margins of which are edged with maroon.
Hardiness
USDA hardiness zone 6a to 9b: from −10 °F (−23.3 °C) to 30 °F (−1.1 °C).
How to Grow and Care
Arums are quite easy to grow. The shade and part shade species need moist but free-draining soil. Their biggest threat comes from drought. However, most species are sun lovers and are grown on what is known as the "Mediterranean Cycle," which is a warm and dry summer and a cool and wet winter. The most important thing with this latter group is drainage. Drainage should be very sharp as they will not tolerate sitting in water at all.
Feeding is a good idea with Arums, especially if they are in pots. Feed with a high nitrogen liquid feed once a fortnight. This will feed the leaves, which in turn will feed the tuber/rhizome.
When potting up tuberous aroids, use a pot three times the diameter of the tuber.
