Grey-white foliage and airy blue-lavender flowers. Does best with dry hot conditions, forming a lovely haze of colour at the middle to back of the border against which so many colours go well. The hotter the location, the happier the Perovskia. The foliage of 'Longin' is not as dissected as the species and is similar to 'Little Spire'. 'Longin' also tends to have a narrower and more upright habit than others in this species. Photo courtesy of Walters Gardens.
