The Philodendron Cordatum, also called Sweetheart Vine or Heart Leaf Philodendron, is a trailing houseplant native to Central America and the Caribbean. This easy-care plant has glossy, heart-shaped, dark green leaves that look stunning in different types of planters and hanging baskets.
In its natural habitat, this plant climbs up trees in the forest canopy. It prefers indirect sunlight and can tolerate many lighting conditions, including low-light shady spots. This makes Philodendron Cordatum a perfect houseplant for any home or office.
Philodendron Cordatum was included in the NASA Clean Air Study and proven to be effective in removing formaldehyde from the air.
Philodendron Cordatum prefers bright, indirect sunlight, but it also tolerates different lighting conditions, including low-light shady spots. Too little light, however, can slow down its growth and makes this plant leggy. Avoid harsh direct sun to prevent scorching leaves.
Check the soil once per week and only water when the top 2" of the soil is dry to the touch. Water thoroughly and drain well after each watering. Crispy leaves mean that your plant needs more water, and yellow leaves indicate that it was over-watered. This plant needs less water if grown in medium or low light conditions.
This plant prefers well-drained, porous soils. It is recommended that you add some pertile to general houseplant potting soil to increase drainage.
This plant grows best in normal room temperatures (between 65°F-80°F). This plant is not frost-tolerant and it does not grow well when the temperature drops below 50°F. Philodendron Cordatum prefers high humidity (over 50%), so mist your plant and use a humidifier when the environment is too dry.
This plant should be fertilized once per month during the growing season (spring/summer) with diluted houseplant fertilizer. You can alternatively use a slow-release fertilizer twice per year.
This plant is mildly toxic if ingested, so keep it out of reach of pets and children.
