On dense foggy mornings, bright clear Hyperion peers through the gloom with intensely fragrant 5" trumpet-shaped lemon-yellow flowers. Widely planted on old farmsteads in Maine, where it became popular in the 1920s. Famous for its heavenly scent, extended blooms—flowers stay open for nearly 16 hours—and ability to rebloom later in the season. Hyperion remains a favorite and is a must-have in the naturalized perennial border.
Midsummer blooms. Native to eastern Asia. Z2. (One-year-old field-grown rootstock with two fans)
