Blue mist shrub is aptly named as its gray-green foliage is shrouded in a cloud of blue from mid to late summer. It is a well-behaved garden plant that is very attractive to butterflies. 'Dark Knight' has deep purple blue flowers closely spaced on long stems.
Tends to bloom earlier than other daisy varieties, with a short stature and tidy, compact habit. White, quilled petals and sunny yellow centers provide a twist on the classic daisy look throughout the summer. From Darwin Perennials.
