Lipstick plant (Aeschynanthus radicans) is a popular house plant with an almost constant display of bright red, tubular flowers, that resemble lipsticks, against trailing, green foliage. Native to the rainforests of South East Asia, Aeschynanthus is an epiphytic plant, which means it doesn’t grow in the ground but instead is found hanging from tree branches, where it gets its moisture from rain water vapour. As a house plant in the UK, it grows well in a free-draining, peat-free potting mix.
