Philodendron Lemon Lime has bright, lime green to golden-yellow heart-shaped leaves and pink petioles. Lemon-Lime kind of reminds us of the Neon Pothos but the Lemon Lime leaves are wider than the pothos. Plus Lemon Limes are upright plants not vines although once they reach about a foot in height their stems often bend and can become vine like looking. As with most philodendron Lemon Lime doesn't demand alot of attention. At maturity, Lemon Lime reaches about 10 to 12 inches in height and 12 to 24 inches wide at maturity.
