Florists variety of Flossflower that we think makes a nifty garden plant too. Large rich violet umbels repeat through summer. Remove spent flowers to encourage more. Full sun and rich, well drained soil. Lightly fragrant and a stupendous cut flower. To 18″ tall and 10″ wide. Deep green foliage and black stems are handsome. Short lived perennial- approximately 3-4 years per plant. Freezes to the ground below 20ºF- resprouts from the base if temperatures never drop below about 10ºF. Often self sows in open disturbed sites- even following hellacious winters that compromise the parent plant. Light summer water- extends bloom. Cutting flowers encourage more bloom. Light sweet fragrance up close. The species is pure light blue and the cultivar ‘Dark Purple’ is just that a deep purple/ blue. See photograph below. Cottage gardens, borders, between established roses, containers.
