Which perennial do you love too much?
Is it just only me but when I have a good experience with a plant in my garden I then go out and buy too many for other areas of my garden. Of course there are so many wonderful perennials but I get fixated.
For example I really like (too much) persicaria Golden Arrow. It's light bright foliage looks so good in shady areas of a garden and by August its spiky red flowers are striking. And they last a very long time. And unlike some other persicaria they are well behaved and not too large.
By the time I saw how great this plant was it was late fall but I still went out and bought *2* more in October 2011 and one more this spring! (All are doing well in 2012)
So what is your Golden Arrow ie which perennial do you have on your brain?
