Zantedeschia pentlandii

Zantedeschia pentlandii

Zantedeschia pentlandii, also known as Arum Lily, is a unique and stunning perennial that produces tall bright yellow flowers through summer. This plant is a must-have for any garden, and its hardiness makes it a great addition to any landscape.

Unlike other plants, Zantedeschia pentlandii dies back to a corm, which stays dormant from October to May. To encourage shooting, the plant can be kept in a warm greenhouse or conservatory. When purchased between these months, you will receive a pot with a dormant corm inside, ready to shoot when the weather warms up.

This plant is best grown in a sheltered position with a loamy soil, and it thrives in moist conditions. While the leaves may be damaged by frost during winter, they will reappear in spring. Zantedeschia pentlandii can reach a height and spread of 1m and has green lance-shaped foliage and bright yellow funnel-shaped flowers.

While this plant is described as tender in most places, we have found it to be as tough as other Arum Lily varieties. However, we recommend protecting it from extreme conditions. It is available in either a 9cm pot or 2 Litre pot.

The hardy forms of Zantedeschia are derived from the species Z. aethiopica and Z. pentlandii, with the latter being known for its striking bright yellow flowers. To ensure the best growth, plant this perennial in moist soil in semi-shade. In mild winters, it may remain evergreen and put on growth through winter, but a sharp frost will not harm the plant.

Zantedeschia pentlandii can also be grown in containers, but it is important to use a loam-based compost and not plant it too deep. Regular feeding and protection from frost are also necessary for container-grown plants. Keep the compost moist at all times for optimal growth.
