Mimosa Pudica

Yes, the roots of the Mimosa Pudica release elements that can smell a bit strong in water. Avoid changing the water in the pot, however, as they contain essential nutrients.

First, be careful of its thorns. Secondly, take good care of it: Mimosa Pudica can suffer from sudden changes. So be sure to repot it, leaving it in conditions (light, temperature, etc.) as close as possible to what it knew in its home garden.

The Mimosa Pudica's flowering is not guaranteed, and above all, it is ephemeral, lasting a few days at most. Perhaps it flowered while you were away, or perhaps it didn't flower at all.
