(Centaurea cyanus) Black ball is a stunning selection of this classic cottage garden flower with deep dark garnet blooms held high amidst silvery green foliage. Bushy branching 2-3' plants make wonderful long-stemmed cut flowers and the edible petals are lovely for fancying up a salad or dessert. One of the coolest looking seeds around, to boot. Similar (or possibly even the same) as the cultivar “Garnet Gem”. Wonderful at attracting pollinators, long-blooming, and cold/frost tolerant. 60 days. UO
