This PDN introduction came to us around 1990 from former garden curator, James Stevenson. Unlike most biennial Sweet Williams, our original clump is now over 15 years old. With so many folks asking about it, we finally got busy propagating and officially introduced it in 2001. Dianthus 'Heart Attack' starts flowering in early spring and continues for months with brilliant red-black, carnation-like, hummingbird-acclaimed flowers atop glossy, dark green, strap-like foliage. Unlike biennial Dianthus barbatus we have grown, Dianthus 'Heart Attack' keeps returning and getting better each year.
