This plant is named for a term used in floristry that means "a pale yellow".

This hardy Hibiscus reaches 4.5 ft. in height supporting many yellow buds that eventually open into 12" ruffled, luminescent flowers. The green leaves are ovate to slightly "cut-leaved".

A very nice accent to many of the other Hibiscus. Patent Pending.
