Philodendron simmondsii – Climbing Form and Deeply Lobed Elegance




Why Philodendron simmondsii stands out
Philodendron simmondsii is a bold, high-climbing epiphyte with massive, triangular, deeply lobed leaves that bring a striking visual rhythm to any indoor space. The lobes — most prominent at mid-blade — curve with elegant precision and fade gently near the apex. Mature foliage can stretch over 80 cm in length, with sinuate margins that give each leaf a carved, sculptural look. The stems exude a resinous scent when disturbed, adding a rare sensory trait to this already impressive species. Reddish clasping aerial roots emerge at each node, and when in bloom, the contrast between the green outer spathe and the crimson interior is simply wild. This plant doesn’t just grow — it performs.


Key traits of Philodendron simmondsii

Massive lobed leaves: Up to 82 cm long, triangular outline with 5–7 side lobes per margin
Sinuate leaf edges: Most pronounced at mid-blade, fading near apex and posterior lobes
High-climbing habit: Develops long internodes and thick, clasping aerial roots
Color contrast in inflorescence: Crimson inner spathe with pale apex and a subsessile spadix
Reddish veins: Primary lateral veins and basal ribs often tinged pink beneath



Natural habitat and growth behavior of Philodendron simmondsii
Native to lowland tropical rainforests of South America, this species grows as a scandent epiphyte, using trees to climb high into the canopy. The stem, up to 10 cm long between nodes, produces multiple aerial roots at each node, aiding in support and moisture capture. Indoors, it can climb over 2 metres when given vertical space and support. During its reproductive phase, stem growth slows and thickens while the plant focuses on flowering. Toxicity: Like all Philodendrons, it contains calcium oxalate and should be kept away from pets and children. 


Philodendron simmondsii care instructions

Placement: Provide vertical support and space for the leaves to fully unfurl
Light: Bright, filtered light enhances leaf form and maintains compact internodes
Watering: Keep soil lightly moist; allow top 3–5 cm to dry between watering
Humidity: Prefers 60–80% humidity for healthy leaf expansion
Temperature: Best kept between 20–28°C; avoid temps below 16°C
Substrate: Use a well-aerated aroid mix with bark, perlite, and coir
Repotting: Every 1–2 years or once roots begin circling the pot
Fertilizing: Feed twice monthly with a balanced liquid fertiliser
Propagation: Stem cuttings with a visible node root easily in sphagnum or water
Hydroponics: Adapts well to semi-hydro setups once acclimated
Pruning: Remove any damaged or overly long growth to encourage branching



Problems and solutions for Philodendron simmondsii

Elongated internodes: Caused by low light — move to a brighter position
Thrips or spider mites: Target young growth — inspect regularly and use neem or insecticidal soap
Yellowing older leaves: May indicate underwatering or nutrient deficiency
Slow growth: Normal in lower light or cooler conditions; boost humidity and warmth



Extra insights for growing Philodendron simmondsii
This species loves to climb — don’t leave it trailing. Support poles or bark planks help anchor the aerial roots and keep the internodes tight. The lobed margins will become more defined with maturity, especially when grown in humid, stable environments. Mimicking its native rainforest canopy conditions — diffused light, stable warmth, high humidity — will allow this plant to develop full-size mature leaves. You’re not just growing a plant here, you’re growing movement and form.


Etymology and classification of Philodendron simmondsii
The genus name Philodendron means “tree lover” in Greek (“philo” = love, “dendron” = tree), reflecting its climbing nature. The species name simmondsii honours a contributor or collector linked to its discovery. It was formally described by Simon J. Mayo in 1981 and published in Aroideana.


3 FAQs about Philodendron simmondsii
Can I grow Philodendron simmondsii without a pole? You can, but it won’t develop mature foliage — this climber needs support to thrive.
Are the leaf lobes always symmetrical? No, they often vary slightly from one side to the other — part of its wild charm.
How often does it flower indoors? Rarely — flowering is uncommon in indoor settings unless the plant is large and mature.
