Echinops bannaticus 'Blue Glow' (Globe Thistle) is a robust, upright herbaceous perennial with intense blue, perfectly round flowers, 1.5 in. across (4 cm), at the end of gracefully curving, unbranched stems. Blooming from early to late summer, they rise above the deeply cut foliage of prickly silvery green leaves. Though they look prickly, they are all show and not prickly at all. Adding outstanding contrast, interest, and color to the summer garden while being trouble-free and low maintenance, Globe Thistle makes an invaluable contribution to the landscape. Excellent for cutting, it flowers more than once in a season. Truly lovely and perfectly suited to the perennial border or the cutting garden.
