Mimosa pudica Care Guide UK: How to Grow the Sensitive Plant Indoors
Mimosa pudica, often called the Shy Plant or Sensitive Plant, is one of the most fascinating houseplants you can grow indoors. Its delicate, fern-like leaves fold inwards when touched, making it a brilliant choice for anyone who loves unusual plants with a bit of personality.
Native to warm, humid regions of South and Central America, Mimosa pudica grows quickly in the right conditions. In UK homes, it is best treated as a short-lived houseplant, annual or biennial, especially as older plants can become a little leggy over time.

What makes Mimosa pudica so unique?
Mimosa pudica belongs to the Fabaceae family, making it a relative of peas. It has fine stems, soft green foliage and, in the right conditions, may produce small pink pom-pom flowers followed by seed pods.
Its most famous feature is its movement. When touched, the leaves fold inwards as a natural defence mechanism. This sudden reaction helps deter grazing animals in the wild and is what makes the plant so intriguing to grow at home.
Good to know: Mimosa pudica is one of the few houseplants that visibly reacts when touched, folding its leaves inwards within seconds.
How does the Sensitive Plant move?
The movement is caused by specialised cells at the base of each leaflet and stalk. When the plant is touched, these cells rapidly lose water pressure, causing the leaves to curl inwards. After a few minutes, once the perceived threat has passed, the leaves usually reopen.
This can also happen at night or in low light. Much like Calatheas, Mimosa pudica responds to changing light levels by adjusting the position of its leaves.
How to care for Mimosa pudica indoors
Mimosa pudica needs a little more attention than some of the easier houseplants, but it is not difficult once you understand what it likes. The main things to focus on are warmth, light, humidity and consistent watering.
- Light: Place in bright, indirect light. An east or west-facing windowsill is ideal. Some gentle morning or evening sun is fine, but avoid harsh midday sun in summer.
- Temperature: Keep warm and away from cold draughts. Mimosa pudica does not like sudden drops in temperature.
- Watering: Keep the compost lightly moist during spring and summer, but never soggy. Reduce watering in autumn and winter.
- Feeding: Feed every two weeks during the growing season with a general houseplant fertiliser. We recommend Liquid Gold Leaf, one of our favourite feeds for encouraging healthy growth and vibrant foliage.
Watering Mimosa pudica
Mimosa pudica prefers its compost to stay lightly moist, especially while it is actively growing. Try not to let it dry out completely for long periods, but avoid leaving it sitting in water.
Top tip: Mimosa pudica prefers consistently moist compost, but it hates sitting in waterlogged soil.
If you are unsure, check the top of the compost with your finger. If it feels slightly dry, it is probably time to water. If it still feels damp, leave it a little longer.

Humidity and soil
The Sensitive Plant enjoys higher humidity, so it can be a good choice for a warm, bright bathroom with a window. You can also increase humidity by placing it near other plants, using a pebble tray or growing it in a suitable terrarium-style environment.
Mimosa pudica enjoys higher humidity levels, making it a fun plant to experiment with in a terrarium. If you're interested in creating your own, take a look at our Build Your Own Terrarium collection.
Use a free-draining houseplant compost that holds some moisture without becoming heavy or waterlogged. A mix with added perlite, vermiculite or grit can help keep the roots healthy.

Should you touch Mimosa pudica?
It is very tempting to keep touching the leaves, especially when you first bring the plant home. However, every movement uses energy. If the plant is touched too often, it can become stressed and may start to respond more slowly.
Worth knowing: Every movement uses energy. Constantly triggering the leaves can stress the plant and slow its growth.
Enjoy the movement, but try not to overdo it. Your plant will stay healthier if it is allowed to react naturally rather than being constantly triggered.
Propagation and lifespan
Mimosa pudica can become leggy as it matures, so many people treat it as a short-lived plant and grow fresh plants from seed. If your plant flowers and produces seed pods, you can collect the seeds and sow them indoors with gentle warmth and consistent moisture.
Regular light pruning can also help keep the plant bushier and more compact.
Common Mimosa pudica problems
Why are the leaves turning yellow?
Yellow leaves are usually caused by overwatering, cold temperatures or low light. Make sure the plant is warm, bright and planted in free-draining compost.
Why is my Mimosa pudica drooping?
Drooping can be caused by underwatering, sudden cold, low humidity or stress. Check the compost first, then make sure the plant is not sitting in a draughty position.
Why has my Mimosa pudica stopped closing?
If the plant stops reacting, it may be tired, stressed or touched too often. Give it bright light, warmth and consistent care, and avoid handling the leaves for a while.
