History / StoryNotes: Pod Parent: Courtade Pink. Bright green leaves with pubescent new growth.

Jungle Jack's source description: Stunning, large, brilliant yellow flower with a small white border. Very compact growth habit with pubescent branches. Vigorous grower and great bloomer. Does not get rust. Citrus and herbal scent. Cold resistant. Best of the Elizabeth Thornton creations. Not a Jungle Jack variety, however we decided to offer it after receiving many requests.
