This is one of a grouping of troughs at our house. The angle of the light and the changing foliage make it easy to tell the season without a calendar.
The dracocephalum turned such a great yellow/orange this year, though I need to divide it next year (it's a flopper).
In the back rank of troughs lives a quince with sedum sieboldii at its feet. I LOVE this sedum in autumn.
