What part of the US are you in?

How is it I knew, before checking the member's page, that that was a picture taken in the UK? Can anyone help me on the indefinable clues which told me that? It often happens on these pages and I'm never quite sure how I know. Does the reverse happen? Is there something there which tells you it's not a US garden?

We been dealing with the related henbit since stopping our preemergent use a few years back. They go away in the heat of summer, but can produce thousands of seeds per plant so will be back unless you break the seed cycle. Keep them cut or pulled before they go to flower. Where they are already in bloom, catch and bag the cuttings if you have a catcher on your mower. I'd do this over resorting to a broadleaf weed killer, especially at this time of year. Improving the overall health of the lawn or ground cover in the infested areas will also help a lot. Fall is the next opportunity to consider applying a preemergent to get it back where the manual methods (cutting/pulling) can keep it under control.

It seems pretty easy to grow it started with just a few lonely leaves. I always add more perlite to potting soil to aid the drainage.
