Which species goes under the common name of Swedish Ivy?

Swedish Ivy is commonly known as Plectranthus australis. This species is a tropical and subtropical member of the mint family and is recognized for its trailing growth habit, fleshy leaves, and small purple flowers. It is often grown as a houseplant or ornamental ground cover, valued for its ability to thrive in a variety of light conditions and for its attractive foliage.

The other species listed do not share this common name. Ficus species typically refer to trees, shrubs, and varieties such as the common fig or rubber plant. Philodendrons are a diverse group known for their striking leaves and are often grown indoors, but they are not referred to as Swedish Ivy. Nephrolepis exaltata, commonly known as the Boston fern, is recognized for its feathery fronds but is unrelated to the Swedish Ivy. Therefore, Plectranthus australis is distinctly identified by this common name due to its unique characteristics and growth habit.
