This dramatic gold hosta was registered by Paul Aden of New York in 1986 as a cross between H. 'Aden No. 217' × H. 'Aden No. 219. The actual originator of this hosta is unknown. It is a large size (28 inches high by 70 inches wide) plant that is often used effectively as a specimen or focal point.

The foliage is slightly corrugated, distinctly wavy and curved at the tip with good substance. Its flowers are pale lavender and borne in July on tall (36 inches) scapes but it is sterile and does not set seeds.

According to The Hostapedia by Mark Zilis (2009), "Since its introduction in the mid-1980s, 'Sun Power' has achieved widespread popularity and is now one of the most recognized cultivars. Though its reputation as a sun-tolerant hosta has been much exaggerated, 'Sun Power' offers distinctive, bright gold foliage. A properly placed single specimen will be attention-getting."

The New Encyclopedia of Hostas by Diana Grenfell (2009) states: "Achieves its best color early and holds it until frosts occur...Becomes much larger given optimum growing conditions...A classic hosta...In late summer the paler colored petiole seems to dramatically pierce the brassy golden leaf blade."

This cultivar was winner of the Benedict Garden Performance Medal for 2016.

In an article about hybridizing by Tony Avent in The Hosta Journal (1996 Vol. 27 No. 1),  Tony gives the following comments on cultivars he has introduced: "H. 'Abba Dabba Do' - a great gold margined sport of H. 'Sun Power'. ..very sun tolerant...makes a grand old clump."

Tony also gives the following comments on cultivars he has introduced:  "...H. 'Outhouse Delight' is our biggest breakthrough, followed by H. 'Elvis Lives'. I am real excited about a coming introduction, H. 'Old Yeller', a cross with H. yingeri and H. 'Sun Power'...pretty incredible...brilliant unique golden color, ruffled leaves, yinger-like flowers...takes full sun...Oh, Baby!"
