Love the hydrangea---even if it doesn't flower, the foliage is lovely. Someone entered a variegated leaved caryopteris at the fair--it won, & looked quite nice. Great MG's, Pixie--such an intense color! Here is a perennial I have that is blooming now--5ft tall--gray-green willow-shaped leaves--the blue is not as intense as the photo--softer & grayer---but I have no idea what it is--has been in about 3-4 years. Can anyone ID it?
