For the last 13 years the All-American Daylily Selection Council has awarded unique and outstanding daylily varieties the prestigious "All-American Daylily" award. Their testing program helps gardeners decide which of the more than 13,000 daylily cultivars in the commercial trade would be the best ones to grow in their gardens. The test plots are located in five different hardiness zones so they offer a broad range of growing conditions. The daylilies are evaluated for 50 different growth characteristics such as disease resistance and length of flowering time. While most daylilies will bloom for two to three weeks in summer, top performers will bloom for 90 days in USDA zone 4 gardens and up to 300 days in USDA zone 9 gardens.
This year's winner is 'Lavender Vista'. This variety produces 5- to 6-inch-diameter, fragrant lavender blooms with a green throat. The plants grow 18 inches tall with evergreen foliage. This variety bloomed for an average of 88 days in trials and flowered in the shade better than other varieties.
