Commonly grown as houseplants, Heart-leaf philodendron are climbing vines that perform well indoors in partial shade. Their leaves are shaped like hearts, and aerial roots help them spread to other regions.
Philodendron scandens (Heart-leaf Philodendron)
Hardiness Zones: 11-12, keep temperatures 60 degrees Fahrenheit or above on all occasions
Height: spreads up to 6 meters (20 feet) tall in its native habitat from the root system, rarely above 1.2 meters (4 feet) tall indoors
Diameter: spreads up to 1.8 meters (6 feet) wide from the root system
Growth Rate: slow to moderate
Root System: produce aerial roots
Subspecies: ‘Frilly Philly’, ssp. oxicardium
Tolerates: drought (moderate), most pest and diseases
Problems (major): none
Problems (minor): aphids, spider mites, scale, root rot in overl wet soils, mosaic virus, leaf spots,
Poisonous: Yes, calcium oxalate crystals can cause pain and swelling in the mouth and throat if ingested. Consuming the foliage or other parts will most likely cause injury. One infant was reported dead due to consuming the leaves, which led to mouth and throat swelling and other health complications. These are toxic to humans and other animals.
Soil requirements: grows in light/sandy, medium/loamy, and heavy/clay soils, tolerates slightly alkaline or acidic soils, requires good draiage, prefers moist, nutrient rich soils
Air requirements: prefers high humidity
Watering requirement: moderate, less in winter
Sun requirement: partial shade, sun scald in full sun and excessive legginess in full shade
Leaf size: roughly 4 inches on juveniles, up to 12 inches on mature plants
Leaf shape: heart-shaped, glossy, dark green, simple
Stem length: up to several meters long in ideal conditions in its native habitat, up to multiple feet long indoors
Stem width: thin
Other stem qualities: light green colored
Flowering structure: greenish-white inflorescence
Flowering frequency: very rare indoors
Fruits: presumably small, red, berry-like
Epiphyte: no, although the vine will grapple onto fences or trees for support
Propogation methods: by cuttings
The leaves are heart-shaped and greatly vary with size depending on the plant.
These are grown as ornamentals inside in temperate climates because of their shade tolerance and attractive foliage.
