'Kenora Valentine' is a large-flowered decorative dahlia, with blood-red double flowerheads 25cm across and dark green foliage. Like all dahlias, it prefers a site in full sun, although it will tolerate some light shade, and grows best in moist but well drained soils.
Dahlias are divided into groups based on the appearance of their flowerheads. Decorative dahlias have fully double flowerheads, with no central disc visible, and the petals have slightly incurved edges and usually blunt points.
