What is difference between smartweed and knotweed?
Specific species are hard to tell apart, but can be broadly classified into two categories: Smartweeds (in which the flowers are in spike-like terminal clusters) or Knotweeds (in which the flowers are clustered in the leaf axils) Vary in size by species.
Why is it called smartweed?
The Latin genus name refers to the swollen nodes on the jointed, slightly angled stems. Knotweed is named for the sheath that encircles the nodes on the stems. The plants are called smartweed because they have a sharp, peppery flavor and their plant juice makes one’s eyes run.
What does knotweed taste like?
Knotweed’s one redeeming quality, then, is that its hollow green stems, segmented like bamboo and freckled with crimson, taste a whole lot like rhubarb (though the two bear no relation). They are tart, crunchy, and juicy; can be eaten raw or cooked; and can lean sweet or savory, depending on how they’re prepared.
Is knotweed poisonous?
No, Japanese knotweed is not poisonous and does not cause burns. Some people get the name confused with Giant hogweed, which can cause burns or Common ragwort, which is poisonous. Both of these are also non-native invasive weeds.
Will goats eat knotweed?

Japanese Knotweed can be identified by its creamy-white coloured flowers (panicles) that bloom as clusters between late August and mid-September [12]. Japanese Knotweed flowers grow up to 10cm long and 0.5cm wide alongside the leaf foliage, creating a dense appearance that often blocks the distinctive stems from view.

In some cases weekly mowing can eventually draw down enough of the plant’s reserves to kill it. The best approach to control is through a combination of cutting and herbicide application.
