Which Barberry Has Thorns?
Barberries are a good choice to design your landscape, but they may equally be challenging to deal with because of their stingy thorns.
No worries, you need not deal with Barberries frequently as the plant requires minimal maintenance. Still, they attract nasty ticks infected by Lyme disease.
Thus, Barberry is banned in Maine, Minnesota, New Hampshire, and New York as the plant is a prime hiding location of those deer ticks.
Moreover, they invade endemic plants and destroy the native ecosystem with their troubling thorns.
There are about 400 Barberry species, including American Barberry, Common Barberry, Japanese Barberry, Red Barberry, and many more.
Most of the common Barberry plants bear three spiny thorns at every node of the plant. Unlike others, every node of Japanese Barberry bears a single thorn.
However, you can also find thornless barberries too. Berberis thunbergii, or Orange Rocket Barberry, is thornless and suits best in zone 4.
Are The Thorns On A Barberry Bush Poisonous?
Although Barberry plants don’t release any poisonous compounds after stinging skin in animals or humans, the infection may occur in the wound caused by the thorns.
The thorn is not toxic itself, but if it pricks on the joints, you may suffer from plant thorn arthritis causing painful joints.
However, the other parts, like leaves, stems, and fruits, are toxic to humans and pets if you or your pets take them in large amounts.
Although a small intake is beneficial, the berberine in this plant makes you suffer from diarrhea, vomiting, and abdominal pain due to high doses.
