This sport of H. 'Guacamole' grows into a large size hosta about 24 inches tall by 54 inches wide. It was registered in 2016 by Bob Solberg of Green Hill Farm in North Carolina. A fast growing plant, 'Ambrosia' has medium blue-green foliage with a pale yellow medial (center) variegation. The leaves are slightly wavy, glaucous on top and have petioles which are pale yellow in the center. The flowers are pale lavender and bloom from mid-July into August on scapes up to 41 inches tall.

The registration materials state: "Waxy leaves are light yellow with a blue margin, fragrant flowers and rapid growth rate...Pale yellow with blue margins become yellow and medium green when the wax disappears."

The patent application lists the following as differences from the mother plant: "In the new Hosta, the leaf margin is blue due to the presence of a glaucous wax as compared to the dark green margin of Hosta 'Guacamole' which has no wax. The leaf center of the new Hosta is a light yellow due to the presence of a glaucous wax as compared to the yellow/chartreuse center of Hosta 'Guacamole' which has no wax."

In Greek mythology, ambrosia was the food of the gods and it made them immortal.
