Marshmallow Arum Lily (Zantedeschia aethiopica ‘Marshmallow’)

Arum Lily Marshmallow

Elegant pink flowering marginal plant for stylish pond edges

Arum Lily Marshmallow is a truly eye catching marginal pond plant, perfect for adding a soft, elegant touch to your pond or water garden. Known botanically as Zantedeschia aethiopica ‘Marshmallow’ Marshmallow, this variety produces stunning pale pink flowers with deeper pink centres, creating a beautiful contrast that stands out against its rich green foliage.

Flowering from late spring into summer, these distinctive blooms rise above the leaves on sturdy stems, forming a striking focal point along pond margins. The gently curved spathes give a sculptural look, making this plant ideal for both modern and traditional pond designs. Whether used as a single feature plant or planted in groups, it brings a refined and sophisticated feel to any setting.

The foliage is equally impressive, with large, glossy, arrow shaped leaves that provide structure and interest even when the plant is not in flower. These lush leaves help soften pond edges and blend planting areas naturally into the surrounding garden.

Arum Lily Marshmallow thrives in full sun to partial shade and prefers consistently moist conditions, making it ideal for pond margins, bog gardens, or damp borders. It can be planted directly into shallow water or kept just at the water’s edge, where it will establish and grow steadily over time.

This plant is also beneficial for wildlife, offering shelter for insects and contributing to a balanced pond environment. While it is easy to grow, it is worth noting that all parts of the plant are harmful if eaten and may cause irritation, so care should be taken around pets and children.

Supplied pre planted in an aquatic basket, this Arum Lily is ready to place straight into your pond, making installation quick and hassle free.

🇬🇧 UK-grown aquatic plant: Grown at a dedicated aquatic plant nursery in the South of England and carefully prepared for delivery across the UK.
