That is just gorgeous. In my best dreams my larkspur will self sow like yours.
I only had about four plants come up from the first sowing last winter.I left them where they were and have great hopes for a nice spread into the pink and white lily patch.
You can barely make them out at tyhe right above the Walkers Low.

This is also the area where I will sow the purple,blue and giant white poppies.
I believe Gemini Sage on Cottage Gardens ,sowed some last year that didnt germinate.
