This picture shows two "Golden Arrows" persicaria. For me they began to bloom in late August and it will continue into October. These plants receive very little direct sunlight and still they flower and their bright green foliage lights up a darker area. I really love this variety...highly recommended.
Thanks Donna. It is one of my favourite plants and because of this I have too many of them. In fact I bet I had already posted about this particular persicaria on DG prior to this new thread...a bit embarrassing if that is the case.
This summer, my afternoon sun has been quite hot and we've had far more sunny, clear days than normal. Maybe I could plant it further back towards the tree line to moderate. I'm still adjusting to the removal of two oaks last fall, letting a lot more light from the west into the various beds. Due to have another tree removed in a few weeks which will probably let in even more light. Only having trees removed for safety issues as they're getting pretty old with lots of dead wood.
