Description Philodendron Red Heart Care Guide FAQ/Common Issues Philodendron 'Red Heart' (Philodendron hybrid) is a rare collector philodendron from the tropical rainforests of Central and South America, where it evolved as a climbing plant in the forest understory. This hybrid has captured the attention of serious indoor plant enthusiasts worldwide for its foliage and trailing vine growth habit. Heart-shaped leaves emerge with a vivid reddish-pink blush before maturing to a deep glossy green. The vines grow long and generously, trailing in a hanging basket or from a high shelf. Leaf surfaces are smooth and slightly waxy, with bold venation. Philodendron Red Heart is grown primarily for its spectacular foliage rather than its blooms, with verified flowering details for this hybrid remaining limited. New leaves emerge continuously in reddish tones. Bright indirect light keeps this philodendron growing well near a kitchen or bathroom where ambient moisture supports its tropical roots. Move it outside in summer to a sheltered, shaded spot, and bring it back indoors before temperatures drop. Rotate it every few weeks for even, balanced growth on all sides. Keep it well out of reach of cats and dogs, as the sap can irritate their mouths and paws. Philodendron 'Red Heart' grows well in bright indirect light and scorches easily in direct south-facing sun. Water it every 7-10 days, allowing the top inch of soil to dry between waterings. Philodendron Red Heart does best in a chunky, well-draining aroid mix of perlite, bark, and potting soil. It prefers temperatures between 65-85°F and should never be exposed to frost or temperatures below 50°F.
