Philodendron selloum (Tree philodendron) - A large shrub to 10' tall and wide with bold shiny, deeply-lobed green leaves up to 4 feet long. The flowers have large white spathes but are inconspicuous under the leaves though older specimens are large enough that the flowers may be seen from below and often aerial roots can also be seen hanging down from the stems or snaking along the soli. This upright species from Brazil has long been grown in California with older plants making dramatic specimen plants. Plant in cool coastal sun to shade inland and irrigate regularly to occasionally - older plants in shade are suprisingly drought resistant. Hardy to short duration temperatures as low as 20 F with some damage to new foliage and reliably hardy to 25 F. There is some confusion regarding the name of this plant and many references that its correct name should be Philodendron bipinnatifidum. The first plant described was Philodendron bipinnatifidum in 1830s by Heinrich Wilhelm Schott from plants collected by him in Brazil and cultivated at Schoenbrunn Palace Gardens, Vienna. Later in the 1850s Karl Koch described Philodendron selloum, a name honoring his source of the plant H. Sello, the head gardener at Sans Souci, the Imperial Prussian estate at Potsdam. Even in the late 19th century there was confusion between these names with some thought may have originated because of the professional rivalry between these two men. If it was a simple naming issue the older name, Philodendron bipinnatifidum, would take precedence, but there are also differences listed in the descriptions of these two species. Most noticeably Philodendron selloum has a spathe that is green colored on the outside while Philodendron bipinnatifidum should be purple-brown. All that we have observed in California have the green spathes. We continue to list it under the name that has long been used for the plant until such time as Philodendron bipinnatifidum is more widely recognized.  The information on this page is based on our research that has been conducted in our nursery library and from online sources as well as from observations made of this plant as it grows in the nursery, in the nursery's garden, and in other gardens where it has been observed. We also incorporate comments received from others and always appreciate 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 that might aid others in growing  Philodendron selloum.
