Thaumatophyllum xanadu were previously known as Philodendron xanadu. They are native to Southern Brazil and Paraguay and are part of the Araceae family. Thaumatophyllum xanadu are a chamaephyte (a plant whose resting buds are on or near the ground) and can grow up to 1.6m wide and 1m tall. Mature specimens develop a 'tree-like' stem at the base of the plant, leaves are yellowish-green, ovate to narrow-ovate with pinnatifid margins and deep lobes. This particular 'Gold' cultivar was created in 1999 in Nonthaburi, Thailand.

Light: Bright indirect light, meaning the plant sees the sun for 0-4 hours per day - this could be through trees or a translucent curtain, it’s important for the plant to see the sky in order to thrive.
 
Water: Allow the first 2-3 inches of mix to dry out. Before watering, ensure the substrate isn’t compacted, if it is, aerate it with a few pokes of a skewer or blunt stick, pour water slowly over the top and allow the water to pass through the drainage holes.
 
Potting mix: A well draining mix composed of coco coir, perlite or vermiculite, orchid bark and worm castings.
 
Fertilising: Feed your plant every other watering during the growing season or when you observe active growth. You can dilute fertiliser to half the recommended amount but never add more.
