This sport of 'Heart Attack' has bright, red-orange flowers when the sunlight shines on them, compared to the black-red color of its parent. This type of Dianthus forms large panicles of flowers, filling in the medium height category with a much-needed red color. 'Heart Attack' made waves when it was introduced because of its perennial characteristic rather than biennial and 'Scarlet Fever' shares this same attribute.
