Renowned for its striking appearance, 'Marshmallow' stands out as a captivating rhizomatous perennial for reliably moist areas, particularly in mild regions where it remains evergreen, forming a cluster of glossy, arrow-shaped leaves reaching up to 45cm (18in) in length. Transitioning from late spring to midsummer, this cultivar boasts a succession of exotic-looking flowers, each up to 15cm (6in) long, adorned with pale pink spathes encircling a vibrant yellow spadix.


  • Garden care:
    These Zantedeschia are grown in aquatic baskets filled with a suitable aquatic compost. The mesh sides allow water to circulate through the compost, compost, supplying both oxygen and nutrients to the roots.

    Place the baskets in shallow water around 10-20?cm (4-8?in) deep, ensuring the crown stays just above the water to prevent rot while the roots remain submerged. For best performance, plant them out as soon as possible in a sunny or lightly sheltered spot.

    During winter, protect the crowns by adding a layer of mulch 5-7cm (2-3in) deep.
    • Humans/Pets: Harmful if eaten; skin irritant/allergen
