The orange lipstick plant, often identified by cultivars like ‘Mona Lisa’, stands out as a captivating houseplant. Its striking tubular orange flowers, which emerge from dark, reddish-brown calyces, create a distinctive appearance. This vibrant plant offers a unique tropical flair, making it a popular choice for indoor gardeners seeking a splash of color and intriguing form. The cascading growth habit further enhances its appeal, allowing it to gracefully adorn hanging baskets or elevated shelves.
Understanding Your Orange Lipstick Plant
The common name “lipstick plant” comes from its brightly colored flower emerging from a darker calyx, resembling a tube of lipstick. These plants belong to the genus Aeschynanthus, with Aeschynanthus radicans being a widely recognized species. As epiphytic plants, they naturally grow on other plants or structures in their native environment, rather than rooting in soil. Their trailing stems can reach several feet, making them suitable for hanging containers. Originating from the humid tropics of the Malay Peninsula, including regions like Thailand, Sumatra, and Borneo, these plants thrive in warm, high-humidity conditions.
Essential Care for Thriving Orange Lipstick Plants
Bright, indirect light is ideal, mimicking the dappled sunlight it receives under a tropical canopy. Too much direct sun can scorch its leaves, while insufficient light may lead to leggy growth and reduced flowering. An east or north-facing window typically provides suitable conditions.
Watering requires careful attention to prevent root rot, as these epiphytic plants do not tolerate soggy conditions. Allow the top inch or two of soil to dry out between waterings, ensuring consistent moisture. Water thoroughly until excess drains from the pot, then discard any standing water. During winter, reduce watering frequency as growth slows.
A well-draining, airy mix that retains some moisture is crucial for healthy root development, given the plant’s epiphytic nature. Consider a mix containing peat moss, perlite, and orchid bark. Avoid heavy, compacted soil.
Orange lipstick plants thrive in warm environments, ideally between 65°F and 75°F (18°C to 24°C). Temperatures below 50°F (10°C) can cause leaf drop, so avoid sudden fluctuations. High humidity (60-80%) is beneficial and can be achieved with a humidifier or pebble trays.
Fertilize during the active growing season to encourage robust growth and blooming. Use a balanced liquid fertilizer, diluted to half strength, every two to four weeks. Reduce or cease feeding during fall and winter when growth slows. Always apply fertilizer to moist soil to prevent root burn.
Encouraging Abundant Blooms
To encourage abundant blooms, ensure sufficient bright, indirect light, as inadequate illumination leads to sparse flowering. A slight drop in nighttime temperatures, especially during winter, can stimulate bud formation. During active growth, a phosphorus-rich fertilizer supports flower production. Light pruning after flowering promotes bushier growth and more bloom sites, as new flowers form on new growth.
Propagating Orange Lipstick Plants
Propagating orange lipstick plants is straightforward using stem cuttings. Select healthy, non-flowering stems 4-6 inches long with at least two or three leaf nodes. Remove leaves from the bottom to expose nodes, where roots will emerge.
Cuttings can root in water or a moist, well-draining potting mix. If rooting in water, submerge exposed nodes, keeping leaves above water, in a warm, bright spot. For soil rooting, plant cuttings in a mix like perlite and peat moss, optionally using rooting hormone. Maintain warmth and high humidity around cuttings, perhaps with a plastic bag cover, to accelerate root development, which typically occurs within 2-6 weeks.
Troubleshooting Common Issues
A lack of blooms often stems from insufficient bright, indirect light or inconsistent temperatures. Yellowing leaves commonly signal overwatering; allow the topsoil to dry between waterings and ensure proper drainage. Brown or crispy leaf edges indicate low humidity or underwatering; increase humidity or adjust watering frequency. Common houseplant pests such as spider mites, mealybugs, and aphids can be managed with regular inspection and treatment using insecticidal soap or neem oil.
