Houttuynia cordata 'Chameleon' - 2016

Neatly contained. In the pond margin, if I recall.

Ours roams free, never a problem......

Sue - yes, in a planting basket. Gets split up about every three years, and the discarded bits potted up for sale (with a health warning!)

Lol!!

I have it contained as well but think to free it in some non-garden space an this property.It is an attractive plant. Mine has very vivid colours.

I also have the plain leaved, double flowered one. Both are restricted to a bucket sunk into the "bog" garden, but they inevitably escape.
