Do not Feed

Latin Name:Polygonum arenastrum
Family Name: Polygonaceae
Knotweed contains oxalic acid, which binds to much-needed calcium and minerals, thus preventing their absorption. It also contains tannins and has diuretic tendencies, so it is best to avoid feeding it to your tortoise, although no harm will come if your tortoise accidentally nibbles some.
Knotweed flowers are mostly creamy whitish-green in colour, but they are also often tinged with pink.
