Good choice Pam. Munstead also good I think from memory.
There's also a white variety Lily but not sure of the variety or if it's as 'flowery' as the usual ones. That's not much help is it ..sorry!
Sorry I wrote Lily when I meant hct...
I have blue Hidcote and white Edelwiess lavenders planted alon the top of a retaining wall where they get good drianage and full sun. They are bothe hardy and flower well each year although the white is slightly longer stemed and flowers later.
Both are pruned right back after flowering is over so are easy to keep compact and tidy though I have to say they look a bit sad after this winter. No doubt they'll perk up though. They usually do and are full of bees buzzing in summer and good perfume.
Lavender and roses - yummy - can we really believe that is going to happen?
Forgot to add I also put some Munstead lavenders in my ros ebed to help keep off the aphids but they don't cope as well with our winters and I've recently had to remove two more corpses. Two left but straggly. i hope they'll be OK after some TLC but will always plant Hidcote in future.
After visiting Norfolk Lavender and seeing a long row of Imperial Gem in a field, alongside many other varieties, I would always choose it for a low edging. The colour is so vivid. The fragrance is wonderful too, but I suspect that can be said for all the English lavenders.
That certainly is a vivid blue but I suspect I need an H5 hardiness rating for my grdaen, even in teh well drained bits.
We have trouble up here with hardiness of lavenders too as it's cold, wet conditions they hate more than anything. They do like well drained soil so the more grit the better I'd say!
The RHS rates most of the English lavenders at H4 (a couple H3-H4), which means hardy throughout the UK, but not where you live, Obelixx. maybe Munstead is H4 and a bit!
I mix grit / sharp sand 50:50 with my lavenders in pots, and give a similar ratio in the planting hole for the rest. I was amazed to find that all my pot grown blue/purple lavenders have survived last winter, despite the -10C we had on quite a few nights (except a silver leaved one called Sawyers and a pink flowered one - forget the name, though I knew both of these were not as hardy as the rest)
Hi Goldilocks, My Hidcotes and Edelweiss lavenders regularly come thorugh -20 to -25C but, as I said, they are in a very well drained spot and get whatever winter sun there is. The Munstead has also been sheltered and well drained but heavier soil with more clay so if I do plant replacements, theer'll be some grit and compost going into the mix. Lavenders are lovely plants to have and great for beneficial insects.
This should be helpful in explaining the RHS H1 to h4 ratings.

Here is the updated RHS hardiness ratings info -
Theyv'e been doing a rethink after tha hard winters of 2009 and 2010 and have come up with a system that includes the extremes of Britain's climates, some of which are similar to continental Europe.
Hidcote is tough and quite tall, and has been a firm favourite in cottage gardens for years. Munstead is rather shorter - and is very easy to grow from seed. One other that I`m fond of is Twickle Purple . Some of the french lavenders are pretty too. If in doubt, why not plant a variety - that would make a lovely feature.
