Norfolk Lavender say "... If pruned correctly a lavender angustifolia, x intermedia and x chaytorae will live for 15-20 years with lavender stoechas living a little less up to 10 years.
Be quite bold lavenders need a good hard pruning after flowering.
The ideal time to prune is late summer when the flowering is over. Trace down the flower stalks to the point where they come out of the bush and then also cut off 1- 2in (2- 5cm) of leaf growth as well as the flower stalk...."
Don't think so ... I wouldn't do it. They're individual flower stems, rather than the sedum's stems with leaves and flowers on the top (not a very scientific way of explaining it but ... )
I think you need a named variety of lavender ... then you'll know what you're getting
My pigs were also Lidl,they've been great,I also got some French Lavender there,and they have flowered since I put them in in June. My Clems were better from there,a Red Montana,and Ernest Markham which is flowering like mad now,unlike the expensive ones I got from the Garden Centre!
The whole truth is an instrument that can only be played by an expert.
I got mine a couple if years ago so they were probably different to yours. I had some of their French lavender too. They did really well until they succumbed to the beast.
Has anyone tried to grow lavender from seed? I've seen lavender seeds for sale but they don't have any specific variety. Would lavender grow true to the parent plant?

I copy them and trim my lavender bushes down to mid shin height after flowering.
