Stories of Luther Burbank and His Plant School, p. 92 (1920)
By Effie Young Slusser, Mary Belle Williams, Emma Burbank Beeson

Burbank is exceedingly fond of the rose, and has sent other noted ones from the school to gladden rose lovers. One of these, the Corona, is indeed a rare and charming flower. It is a climber, produced from seedlings of the crimson rambler. Its flowers resemble Chinese primroses more than they do real roses, and they grow in very large clusters. It is a fine bloomer and forms a bower of rare loveliness throughout the season. Its blossoms possess a quality entirely new in the rose, which causes the flowers to remain fresh on the bush for weeks, where others fade and drop their petals in a few days.
