Lysichiton americanus, a very hardy cousin of arum, is a perennial plant found in marshes. It is particularly unique and very decorative in a pond or along a riverbank. It also serves as support for unstable banks. It flowers in spring, before the foliage emerges, with large buttery yellow spathes emerging at ground level. It is best reserved for medium to large ponds with an extensive shoreline.

Lysichiton americanus belongs to the Araceae family. It is naturally found in wetlands along the northwest coast of the Pacific. It is a slowly growing rhizomatous plant, with a rosette habit, reaching a minimum height of 80cm (32in) and a width of 60cm (24in). It flowers in May-June before the deciduous foliage appears, and continues to bloom afterwards, creating a striking contrast. The yellow spathes surrounding a green spadix can reach up to 15cm (6in) in length, and emit a distinctive cabbage-like odour. This unique scent may not appeal to everyone, but attracts pollinators. The elongated heart-shaped leaves have a medium green lamina that is veined and very shiny. The rhizome of this aquatic plant is underground and creeping.

This hardy plant is suited to a cool climate. It can withstand temperatures as low as -20°C (-4°F) in winter. It thrives ideally on the banks of a body of water or a stream. It is impossible to resist these giant arum flowers. As soon as they bloom, the body of water that hosts them takes on an exotic air. Combine it with other bankside plants such as Siberian irises with blue flowers, molinias with beautifully bluish leaves, or Chinese loosestrife, which will also transport you. If the pond is very large, try planting it with Gunnera manicata.
