Return of the Lupine

We have a raised flower bed in the front yard that I built a few years ago as a 'stage' for a tall welded sculpture I made in a welding class many years ago. I planted the flower bed with Lupine and they did fine for 2 or 3 years then seemed to die out. For the last two years there have been only a couple of very small plants with no flowers but for some reason this year they are back in full force. Last night I was out making some photos of our flowers and this trio in front of the RR tie that the sculpture is mounted on caught my eye. Canon G10, f.4 at 1/30th sec., handheld.
