Planter bowls are an object introduced in The Sims 3: Supernatural that allow Sims to grow plants in them. They returned in the base game of The Sims 4.

Planter bowls can be purchased from the Plants section, under Decor, in Buy mode. They can be used indoors and outdoors and take up one tile of space. This is useful for Gardening in the winter because plants will become dormant if left outside.

The Sims 4
Planter bowls can be purchased from the Activities and Skills section, under Miscellaneous, in Buy mode or the Outdoor plants section in Build mode.
