Plectranthus sp. (Plectranthus)

Plectranthus is a diverse genus of aromatic tropical and subtropical plants in the mint family (Lamiaceae), grown for their ornamental foliage and adaptability to containers and shaded gardens.

Native primarily to Africa, Madagascar, Asia, and Australia, the genus spans a wide range of habits - upright, trailing, shrubby, and semi-succulent - occurring in habitats from forest understories to rocky slopes and seasonally dry regions. Most species are recognized by their soft textured leaves with scalloped margins, square stems, and aromatic oils released when the foliage is touched. Leaf color varies widely across shades of green, silver, purple, gray, or cream, often with variegated or velvety surfaces. Flowers are tubular, arranged in spikes or branched inflorescences, and commonly appear in white, lavender, pink, or pale purple tones.

Plectranthus generally prefers bright filtered light or partial shade, well-drained soils, and moderate watering with some drying between irrigations. Most species adapt well to containers, hanging baskets, and shaded patios. Cold tolerance varies, but most are best suited to USDA Zones 9-11 and should be protected from frost.
