10 Medicinal Health Benefits of Coleus (Plectranthus scutellarioides)

Coleus, scientifically known as Plectranthus scutellarioides, is a vibrant and ornamental plant appreciated for its striking foliage and ease of cultivation. Belonging to the Lamiaceae family, which also includes mint and basil, coleus is native to Southeast Asia and has become a popular choice for gardens, landscapes, and indoor spaces around the world.

One of the most distinctive features of coleus is its colorful and variegated leaves. The foliage can exhibit a wide range of hues, including shades of green, pink, red, purple, and yellow, often in intricate patterns and combinations.

The leaves come in various shapes, from serrated and lobed to deeply cut, adding to the overall visual appeal of the plant.

Cultivating coleus is relatively straightforward, making it an ideal choice for both experienced and novice gardeners. The plant thrives in well-draining soil and prefers partial to full shade, although some varieties can tolerate sunnier conditions.

Regular watering is essential to keep the soil consistently moist, and it’s advisable to fertilize coleus during the growing season to support robust foliage development.
