About Aeschynanthus 'Mona Lisa'

Aeschynanthus 'Mona Lisa' · also called Mona Lisa lipstick plant · flowering

Aeschynanthus 'Mona Lisa' is a popular lipstick-plant cultivar grown for its glossy deep-green leaves and abundant bright red tubular flowers along trailing stems. An easy, free-flowering epiphytic gesneriad, it shines in hanging baskets. Give it bright indirect light, warmth, moderate humidity and a slightly snug pot, letting the surface dry between thorough waterings.

Plant type: flowering

Watch for — Poor flowering: Insufficient light or too large a pot reduces blooms. Provide bright indirect light, keep the plant slightly pot-bound, and feed with high-potash liquid in summer.

The reasons aeschynanthus 'mona lisa' isn't blooming

Almost every non-blooming aeschynanthus '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 aeschynanthus '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 aeschynanthus 'mona lisa' to flower

Maximise sun. Give aeschynanthus '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 aeschynanthus 'mona lisa' and get the feeding right with the aeschynanthus '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

Aeschynanthus '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.

For everything else this plant needs day to day, see the full aeschynanthus 'mona lisa' care brief and its watering schedule — a stressed, badly watered plant rarely has the energy to flower at all.

Why won't my aeschynanthus 'mona lisa' flower?

The most common reason it is not happening: Too little sun — most of these need full sun (or very bright light) to flower well; shade gives leaves, not blooms.
