The Lipstick
plant is Aeschynanthus lobbianus.
To bloom, first, they need lots of bright light all year round, although they also need protection from direct sun in the midday hours. Second, they should be kept in small pots; repotting discourages flowering. Third, they require warm temps, never below the mid 60's, even in winter. Fourth, keep the soil evenly moist - too much or too little water will discourage blooms. Finally, younger
plants are better bloomers than older
plants. Regular pruning will help keep them young.
It will get leggy if it is not pruned regularly. The best time to prune is when there are no buds in formation. Prune the longest stems back to several inches above the soil. Remember, the new growth will start at the point that you cut back to, so you should cut back pretty far to produce fullness in the center of the
plant.
