Mimosa pudica (touch-me-not, Sensitive plant) seeds are very nice to grow and to have. The leaves close when you touch them. Mimosa pudica is related to Acacia.
Pour hot water (80 °C) on top of the seeds. Let the seeds cool down and then divide the seeds on a mixture of cocopeat and perlite. Slightly press the seeds into the soil but do not cover them with soil. Your soil should be moist all the time but not soaking wet. Maintain a high air humidity as well. These seeds germinate at high temperature at around 30 °C.
Make sure you ventilate after germination but maintain a high air humidity. Also never let the soil dry completely.
