Dear Chris, the lavender photos that you have selected from my portfolio are Lavender Hidcote. I tend to use this one as it has a good compact growing habit and grows to around H.60 x S.60 cm

Chris, I designed and installed this space about 10 - 15 years ago, so honestly I'm not sure. We most likely used Hidcote. I love the look of lavender, but stopped using it in rows or masses. I've found we always need to replace a few of them. The group looses its impact when you constantly have have new ones mixed in. Hope this helps.
