Philodendron selloum, now scientifically known as Thaumatophyllum bipinnatifidum, is a popular houseplant celebrated for its dramatic, deeply lobed foliage and tropical appearance. This plant, often referred to as the Split-Leaf Philodendron, brings a lush, architectural element to indoor spaces. Its striking leaves and adaptable nature contribute to its widespread appeal among plant enthusiasts. This article explores the distinct forms and cultivars of this impressive botanical specimen.
Key Varieties of Philodendron Selloum
The cultivar ‘Hope’, also known as ‘Hope Selloum’, presents a classic representation of Thaumatophyllum bipinnatifidum. Its leaves are deeply dissected, featuring prominent lobes that give it a distinctive appearance. This variety can achieve substantial dimensions, reaching 10 to 15 feet tall and wide indoors. As it matures, ‘Hope’ develops a sturdy, tree-like trunk, contributing to its grand presence.
‘Shangri-La’ offers a more compact and upright growth habit compared to ‘Hope’. Its foliage tends to be denser, with leaves more tightly packed along the stems. This cultivar typically grows to a height of 24 to 36 inches and a spread of 36 to 48 inches indoors, suitable for smaller spaces. The leaves of ‘Shangri-La’ maintain the characteristic lobed form but appear less deeply cut than ‘Hope’.
For those with limited space, ‘Little Hope’ is a dwarf variety that retains the deeply lobed leaf structure of its larger relatives, bred for its smaller stature, generally growing between 2 to 3 feet tall and wide. Its manageable size makes it an excellent choice for tabletops, shelves, or smaller corners, offering the aesthetic appeal of larger varieties in a contained form.
Another compact option is ‘Super Atom’, notable for its smaller size and distinct leaf characteristics. This cultivar often remains under 2 feet in both height and width, a miniature version of the species. ‘Super Atom’ leaves are typically less deeply lobed and more rounded than other varieties, contributing to its unique appearance. While often associated with Philodendron, it is a distinct Thaumatophyllum cultivar, appreciated for its small stature and unique foliage.
Selecting the Right Philodendron Selloum Variety
Choosing a Thaumatophyllum bipinnatifidum variety depends on specific needs and its environment. Space is a primary consideration, as mature sizes vary significantly. ‘Little Hope’ or ‘Super Atom’ suit smaller rooms or desktops due to their compact growth.
Conversely, if ample room is available for a grand botanical statement, ‘Hope’ can fill a large area. Desired aesthetic, like leaf density or plant shape, also guides selection. Light conditions are also important, as all varieties prefer bright, indirect light.
General Care for Philodendron Selloum Varieties
All varieties of Thaumatophyllum bipinnatifidum thrive in bright, indirect light, promoting leaf development. Direct, intense sunlight can scorch foliage. Allow soil to dry slightly between waterings to prevent root issues.
A well-draining, rich potting mix supports healthy root growth. While they appreciate higher humidity, they adapt well to average household humidity. During the active growing season (spring through summer), apply a balanced liquid fertilizer periodically.
Distinguishing Philodendron Selloum Varieties from Similar Plants
Thaumatophyllum bipinnatifidum, formerly Philodendron selloum, was reclassified due to botanical distinctions. It is sometimes confused with Thaumatophyllum xanadu (formerly Philodendron xanadu).
A key distinguishing feature is leaf structure; T. bipinnatifidum has deeply lobed leaves with prominent sinuses and develops a noticeable trunk. In contrast, T. xanadu has more numerous, less deeply lobed leaves that appear bushier and generally does not form a prominent trunk.
