Abstract
A new and distinct hardy perennial Heliopsis plant named ‘Sundial’ with dense, tall, rounded, extensively-branched habit. The foliage is dark green with burgundy highlighted margins and lanceolate to ovate on strong stems. Freely-flowering single to semi-double inflorescences in a capitulum with overlapping rows of ray florets beginning in early July and continuing for about 6 to 8 weeks. The ray florets begin a burnt orangish-red and lighten to golden yellow. The new plant is useful in the landscape en masse, as an accent, in containers or as cut flowers.
