The stem is erect in young plants, but becomes creeping or trailing with age. It can hang very low and become floppy. The stem is slender, branching, and sparsely to densely prickly, growing to a length of 1.5 m (5 ft).
Common name: shameplant, touch-me-not, muttidare-muni,
Bloom time: summer
Height: 2 foot tall
Difficulty level: easy to grow
Planting & Care
The leaves also close under various other stimuli, such as touching, warming, blowing, or shaking. These types of movements have been termed seismonastic movements. The stimulus is transmitted via action potentials to the pulvini of the plant, where contractile proteins and aquaporins induce the movement of water and electrolytes out of the cell.
Sunlight: Full Sun
Soil: well-drained soil
Temprature: 18 to 21 °C
Fertilizer: Apply any organic fertilizer
- Growing plants can be inexpensive, particularly when growing them from seed.
- Seeds of plants flowers should usually be sown directly into the sunny flower bed, as developing roots do not like to be disturbed.
- Apply a high-potassium liquid fertilizer every 2 weeks from early spring until 6 weeks after flowering.
- Keep moist in winter
It is not known exactly why Mimosa pudica evolved this trait, but many scientists think that the plant uses its ability to shrink as a defense from herbivores. Animals may be afraid of a fast moving plant and would rather eat a less active one. Another possible explanation is that the sudden movement dislodges harmful insects.
Luckily, plants are deer-resistant, so they might help keep nearby flowers from being eaten.
