Philodendron mexicanum

Philodendron mexicanum is a wet-tropical climbing species with glossy, arrow-shaped green leaves and red undersides that are especially visible on juvenile growth. As the plant matures, the blades become larger and more defined, with the climbing stem producing aerial roots at the nodes.

Younger leaves show the red-backed colour most clearly, while older foliage develops the broader sagittate outline typical of the species.

• Leaf shape: Arrow-shaped to hastate blades with a broad base and pointed tip.
• Leaf colour: Glossy green upper surfaces with red undersides most noticeable on younger leaves.
• Growth habit: A climbing Philodendron with aerial roots along the stem.
• Native range: Recorded from Mexico to western Colombia in wet tropical forest conditions.

Philodendron mexicanum care for climbing growth

Give Philodendron mexicanum a moss pole, plank or other vertical support so the stem can attach as it lengthens. Bright indirect light keeps the growth compact and reduces stretched internodes, while harsh direct sun can mark the leaves, especially on softer new growth.

• Support: A vertical surface gives aerial roots somewhere to attach as the plant produces larger, more defined blades on upright growth.
• Light: Bright indirect light, with protection from strong direct sun.
• Water: Water when the upper part of the substrate has dried, then let excess water drain fully.
• Humidity: Moderate to higher humidity helps new leaves open cleanly, especially during active growth.
• Substrate: Use a chunky aroid mix with bark, coarse fibre and mineral components so air reaches the roots.
• Temperature: Keep warm and stable, away from cold windows and cold wet substrate.

Philodendron mexicanum leaf size, roots and pests

• Small leaves or long gaps between nodes: Usually linked to weak light, missing support or both.
• Yellowing lower leaves: Check for dense, wet substrate around the roots.
• Dry new leaves: Increase humidity around active growth and keep watering consistent without leaving the pot waterlogged.
• Pests: Inspect new leaves, petioles and undersides for thrips, spider mites, mealybugs and scale.

Philodendron mexicanum safety, name and publication

Keep Philodendron mexicanum away from pets and children, as the plant contains calcium oxalate crystals. Sap may irritate sensitive skin.

Heinrich Wilhelm Schott published the genus Philodendron in Wiener Zeitschrift für Kunst 3: 780 in 1829. The genus name comes from Greek-derived roots meaning “tree-loving.” Philodendron mexicanum was described by Adolf Engler in Flora Brasiliensis 3(2): 143 in 1878. The species epithet mexicanum means “Mexican” or “from Mexico.”
