Houttuynia

Latin name
Houttuynia cordata
Common name
Houttuynia
Type
Rhizomatous groundcover perennial
Family
Saururaceae

Houttuynia is a very decorative perennial groundcover, appreciated for its heart-shaped foliage and spreading habit. It adds beautiful texture to cool garden areas, semi-shaded borders, landscaping around ponds, and places where the soil remains moist. Its dense foliage quickly covers the ground, creating a natural, lively, and slightly wild effect in flowerbeds.

Easy to grow, houttuynia prefers a location in partial shade or gentle sun, in fresh to moist, rich, and well-drained soil. It tolerates moisture-retaining soils very well and can be used on banks, in cool areas, or in more shaded corners of the garden. As its growth can become vigorous when it thrives, it is recommended to plant it in a confined space or in a container to better control its spread.

Hardy, original, and very versatile, houttuynia is ideal for gardeners looking for an easy perennial for cool or partially shaded areas. It pairs well with hostas, ferns, carex, astilbes, and other plants suited for moist gardens. It is an excellent plant for adding texture, movement, and a natural groundcover effect to semi-shaded landscapes.
