About Lipstick Plant 'Mona Lisa'

Aeschynanthus radicans 'Mona Lisa' · also called Mona Lisa Lipstick Plant · flowering

'Mona Lisa' is a free-flowering lipstick plant with glossy, leathery green leaves on trailing stems and clusters of tubular red blooms that emerge from dark calyces like lipstick from a tube. An epiphytic Southeast Asian trailer, it thrives in a hanging basket with bright indirect light, warmth, humidity and a slightly dry-between-waterings routine.

Plant type: flowering

Watch for — No flowers: Insufficient light or a too-comfortable warm winter prevents budding. Provide brighter indirect light and a slightly cooler, drier winter rest to trigger bloom.

The reasons lipstick plant 'mona lisa' isn't blooming

Almost every non-blooming lipstick plant 'mona lisa' traces back to one of these, roughly in order of how common they are:

Too little sun — most of these need full sun (or very bright light) to flower well; shade gives leaves, not blooms.
Too much nitrogen feed, driving lush foliage at the expense of flowers (very common with general or lawn feeds).
The plant has not been deadheaded, so it stops flowering once it sets seed.
Irregular watering — drought or waterlogging at the budding stage makes buds abort.
It is still too young or was checked by a transplant and is rebuilding before flowering.

Feeding lipstick plant 'mona lisa' a high-nitrogen general feed and growing it in too little sun — you get a big leafy plant and almost no flowers.

The fix — how to get lipstick plant 'mona lisa' to flower

Maximise sun. Give lipstick plant 'mona lisa' the sunniest spot you have — for most bedding and fruiting plants, more direct light directly means more flowers.
Switch the feed. Move off high-nitrogen feeds and use a higher-potassium "bloom" or tomato-type feed as it comes into flower.
Deadhead regularly. Remove spent flowers often to keep it producing more rather than stopping to set seed.
Water consistently. Keep moisture even through budding and flowering — drought-then-flood swings make buds drop.

Light and feeding do most of the heavy lifting here. Dial in the spot with the light guide for lipstick plant 'mona lisa' and get the feeding right with the lipstick plant 'mona lisa' fertilising schedule — the wrong feed (too much nitrogen) is one of the most common silent reasons a healthy plant makes leaves instead of flowers.

Bloom season and what to expect

Lipstick Plant 'Mona Lisa' flowers across its growing season (mostly summer) and, kept fed and deadheaded, can bloom for many weeks or right up to frost.

Post-bloom care so it flowers again

Deadhead, keep feeding lightly, and many will rebloom; collect seed from the best plants at the end of the season if you want to grow them again.
