Dahlia 'Mystery Day'
 
A dramatic and unmistakable dahlia, Mystery Day produces richly saturated deep burgundy-purple blooms dramatically tipped in crisp white, creating a bold high-contrast effect. The fully double flowers have beautifully arranged petals and a velvety texture that gives the blooms exceptional depth and elegance. No two flowers are exactly alike, adding even more visual interest through the season.
 
Originally introduced in the Netherlands, Mystery Day is prized for its strong stems, excellent garden performance, and standout coloration in floral arrangements. The striking bicolor blooms pair beautifully with whites, dark foliage, and softer pastel flowers in cutting gardens and borders.
