The leaves of the swallowtail plant are beautiful and green all year round, so it is also called the jade tree. It contains euphorbia oleifera.

If you have a clematis planted at home, be sure to prevent children from coming into contact with it to avoid accidents.

Mimosa has lavender velvety flowers and its petioles are sensitive. Due to the turgor pressure of the leaves, the leaves will slowly close if they are slightly touched, hence the name mimosa.
