Verbena 'Seabrook's lavender'

Oh, I see you also have Seabrooks lavender, lovely isn't it? Have a go at cuttings like me.

I'd like some advice as to how, please Holly, because I do like it and would like spares in case it succumbs during the winter!

It's just like taking penstomen cuttings, take strong side shoots from the main stems cut below a leaf node and pinch out the flower tip. I have used a cutting compost with some vermiculite in it for drainage, water in and hope for the best. Do quite a few in case some fail as they usually do, Bonariensis is really easy as i have done these for some years now and given lots to friends and family.
