And zone 7 where?

Here in zone 10 (theoretically) San Francisco, English lavendars bloom much later than nearby counties with more summer heat. Like the hated real estate agents say: location, location, location.

Maybe Sweet Lavender?

If by Sweet Lavender you mean Lavandula heterophylla, no, the leaves are wrong.

And again, I ask where thefukarwe? Nod to Precilla, Queen of the Desert...

I see that Houzz stripped profile infos such as location and zone

So put that info. into the post or add it to your screen name. We still don't know your location.
