Succulents are suitable plants for the south window side. As they come from semi-deserts and deserts, they love sunshine and warmth. If you feel like having one little succulent is not extra enough, make a composition consisting of several species: Lithops, Haworthia, Echeveria, and other plants will look cute together.
These mesmerizing little ones require little maintenance. However, for their comfortable existence, they must be provided with a well-drained substrate.
