I have quite a few of these plants in my garden, and, judging from the shape of the leaves, I thought they were going to develop into brightly colored verbena, either the short ones, or possibly the very tall spindly ones that bear small purple flowers. I waited with great expectations until this week (mid-July), and all that has appeared is tiny little white flowers in the axils. The plants are quite bushy and healthy and I thought they had developed from plants which had self-seeded last year. Maybe they have reverted from hybrid F1 plants? My garden is in London - temperate climate.

Following on your comment, cat on a soapbox, I looked at lots of photos on Google, and it's definitely not white vervain, and maybe it isn't even verbena, although the leaves tell me it is! I'm dying to know, so will take it to local garden centre
The flower leads me to the laminacea family which is similar to verbena.
\you were right cat on a soapbox when you contacted me and said it's gypsywort or lycopus europaeus. How disappointing to find it's a weed, and not a type of verbena after all
Although not as showy as a verbena and a bit invasive, it is a nice pollinator attractant and has an interesting history as a dye and medicinal herb :)
