Eryngos

Blue sea holly or...

Eringium.

Eringium.

That's these.

It says blue, but they're more purple.

Both seem to be equally effective.

The first being thorns, which perhaps Josie might, might talk about first, and it's basically a physical barrier, so whether it's holly, sea holly, brambles, and with us it's rose pruning.

So Josie, will you just talk us through that system?

Yes.
