From Beate Zillmer of Zillmer Pflanzen in Uchte, Germany. Imagine 'East Friesland' with violet blue flowers and glowing purple stems. Incomparable! Its tidy upright habit makes an excellent companion for Geranium, yellow Baptisia, and purple Heuchera.
A profusion of blue-purple pincushion flowers. A fantastic performer and butterfly magnet, flowering continuously from May to killing frost. Top ten container and sunny border plant and cut flower.
