Thaumatophyllum xanadu 'Lemon' – Growth Facts and Easy Care Tips


Thaumatophyllum xanadu 'Lemon' is a vibrant cultivar with golden-chartreuse foliage that instantly stands out. Each leaf is deeply lobed, radiating out like a sunburst from its thick petiole, but instead of the usual green, this variety glows with a lemony hue that shifts slightly with light and age. Compact and self-heading, it forms tidy clumps that stay low and wide, giving you structured but lush growth without the need for climbing support. The colour contrast is especially striking when paired with darker-foliaged plants. It’s a slow, steady grower that brings bold colour and texture to any indoor plant setup.

Botanical Background and Habitat of Thaumatophyllum xanadu


Thaumatophyllum xanadu is a self-heading aroid originally developed in cultivation and once considered a Philodendron. It is thought to descend from species native to Brazil’s subtropical forests, where warm temperatures (22–28 °C), moderate humidity, and filtered light dominate. Unlike many aroids, it doesn’t climb or trail but maintains a bushy structure from a short central base.
‘Lemon’ is a cultivated colour variant selected for its striking foliage tone. Like other Thaumatophyllum types, it contains calcium oxalates and should be considered toxic if ingested by pets or humans.
