Botanical Name: Philodendron bipinnatifidum
Another dependable house plant from the Araceae family, the split-leaf philodendron also happens to be one of the most captivating.
This stunning philodendron plant is a tree-like shrub. Young plants have sturdy, upright stems, which tend to lie horizontally as the plant ages. They eventually sprawl to become twice as wide as they are tall, so give your house plant plenty of room to spread out.
Big leaves are dust-catchers. To clean them, gently wipe the leaves with a damp cloth.
The foliage is stunning. When young, the glossy, heart-shaped leaves are deeply indented, and become more deeply cut as they grow. Some varieties of split-leaf philodendron have wavy margins.
Repot in spring or early summer. Use a container with drainage holes to prevent root rot.
Height: To 4 ft (1.2 m) indoors
Light: Moderate to bright light. No direct sun, which can cause brown scorch marks on the leaves.
Water: Keep soil moist spring through fall. Allow surface to dry out between waterings in winter. Yellow leaves are caused by overwatering.
Humidity: Tolerant of dry air, but likes humidity. Mist foliage occasionally.
Temperature: Average to warm 60-80°F/16-27°C
Soil: Peat moss-based potting mix.
Fertilizer: Feed monthly spring through fall with a balanced liquid fertilizer diluted by half.
Propagation: Division. Cut through the thick roots with a serrated knife and pot up the plants separately.
Long aerial roots may appear near the base of the plant. Tuck them back into the pot.
This plant is also known as P. selloum and may be sold under that name.
A few named varieties make good house plants.
'Xanadu' philodendron is a newer cultivar with smaller leaves than the species and only grows to 3 ft (90 cm) wide.
'Hope' is a vigorous, full-sized hybrid. 'German Selloum' has finely cut leaves with wavy lobes.
There is a similar-looking plant that goes by the same common name. Swiss Cheese Plant isn't a philodendron at all -- it is a Monstera deliciosa.
