When to plant young lavender

Hi, I'm hoping to plant a lavender border in my front garden. It is a narrow border next to the drive, against a South West facing fence. I read that lavender is best planted in late spring, but have succumbed to temptation and bought a couple of 'end of season' cheap packs of young plants. They are probably in the equivalent of 7cm pots, so quite immature, but look healthy. Would it be best to plant these now, or to pot them on and keep in an unheated greenhouse until next spring? Any ideas?

The only thing l would say about keeping them in the greenhouse is that the atmosphere can get very moist/humid. Depending on whereabouts you are, l would be more inclined to keep up them up against the house wall and keep an eye on the drainage.
If you have a coldframe so much the better. I have young lavender plants in an coldframe with the lid open, for protection against the worst of the Winter wet.
If the weather reaches "Beast from the East" levels then l would close the frame and maybe also put some fleece over the top of the plants, but l think it's usually wet that does for lavenders rather than the cold.
I'm assuming that you're talking about English lavender rather than a French variety ?
PS. I love the Herault region, we spent 2 happy summers on our boat on the Canal du Midi.
If the roots are bursting out of the bottom of the pots, personally l would pot them on, but only to 9cm square pots. If they're sitting in too much compost they may suffer, but a bit more fresh compost and teasing the roots out a bit shouldn't do any harm.
If you've got any doubts, if you post a couple of photos say one showing them in the pots and one plant that you've taken out of the pot so we can have a look at the rootball, that might help
