Philodendron Xanadu™ ['Winterbourn'] (Winterborn Philodendron) - An evergreen dense low spreading tropical plant that can form a clump nearly 3 feet tall by 5 feet wide over time. It has deeply dissected, lobed 12 to 18 inch long by 8 to 12 inch wide glossy green leaves that hang slightly downward from long smooth upright petioles. Not often seen are its flowers, which have dark red spathes. It also is seems to produce less noticeably, the aerial roots so characteristically seen trailing to the ground on its big cousin Philodendron bipinnatifidum (P. selloum), but contrary to what we previously stated about this plant, we have it on good authority that these roots do actually form on Xanadu. Plant in full sun (coastal), bright shade or part day sun and irrigate regularly, especially in the warmer months. Give ample fertilizer to keep foliage a deep green. Hardy to around 25 F. This is a great plant for use in a mass as a mid-height groundcover, as a foundation planting or in a container - adding a touch of tropical flare to the landscape. It is also a nice interior house plant. This plant was originally reported to be a selected chance seedling that arose in 1983 in a Western Australian nursery. At that time it was given the name Philodendron 'Winterbourn' and was protected under Plant Breeder Rights in Australia, it was then renamed Xanadu by House Plants of Australia and released as their plant of the year in 1988 and this name was trademarked in the US (serial # 73662247) and using the cultivar name 'Winterbourn' it was given the US Plant Patent PP7,030 on January 19, 1988. This patent has since expired and there are now substantiated claims that this plant is not a hybrid or nursery grown cultivar but actually originated from the seed collected from a wild collected plant in Brazil. This plant was described as Philodendron xanadu Croat , Mayo & J.Boos as published in Aroideana; Journal of the International Aroid Society 25: 63 (2002 publ. 2003). If this name holds true it presents problems for the existing Live US trademark as a specific epithet cannot be trademarked but in this case the trademark was established prior to the plant being described as a species - a bit of a mess. Our plants purchased from Twyford International.  Information on this page is based on research conducted in our nursery library, from online sources, as well as from observations made of this plant as it grows in our nursery, in the nursery's garden and in other gardens where we have observed it. We also will incorporate comments received from others and welcome getting feedback of any kind from those who have additional information, particularly if this information is contrary to what we have written or includes additional cultural tips would aid others in growing Philodendron Xanadu™ ['Winterbourn'].
