'Glen Luminaria' is a frosty blue-green at first, gradually changing to softly glowing gold. Very sun-tolerant (like all GBF seedlings, always grown in full sun), holding the frosty bloom into August, when pale lavender flowers are displayed on 2' scapes.
Good rate of growth.
The original specimen was five feet across. The slightly wavy, moderately corrugated leaves emerge a frosty light blue and gradually turn a soft gold, which intensifies at the end of the summer, when the wax is burned off and the leaves are shiny.
The substance is better than average.
