Although this plant is a an excellent ground cover, in my area, zone 8a, it is a very aggressive plant. If you grow it in raised beds, it will cover the bed. It is not a plant that I recommend to gardeners in my area.

Houttuynia cordata is an important herb used in S.E. Asian cooking, particularly popular in Vietnam where it is used fresh in cold rolls, salads and other dishes. Rarely cooked it may be added chopped to a soup at the end of cooking. Should be grown in a container to prevent it becoming rampant. Propagation is easy by division or stem cuttings. Very worth while herb in my opinion.

although this plant is beautifully variegated and has a sweet flower, and a citrusy smell, it is worse than mint as far as being invasive. be careful where you plant it - it will take over everything! i have just pulled up about a 3' X 10' area where it killed my black eyed susans and a hosta. it even grew under my deck! it has running tubers underground, so it is no easy task to get it all pulled up, and "round up" doesn't even kill it all. a great plant in a confined area or as a total groundcover - just be sure you want it where you plant it!

This is a lovely, cheerful slow growing ground cover that grows in shade and requires little to no care. Reportedly, it can be aggressive when grown in wet full sun.
We had to remove all the Houttuynia due to a broken water pipe. I carefully removed and replaced all of it, taking as much of it in soil as possible, hoping to do little damage. Instead, when I replaced it, it went bonkers for the first time in six years. Now I have hope this will one day cover an entire shaded area.
