Dear all, Curious indeed the differences between Paul and Mary Sue's Ornithogalum. >Paul said "Ornithogalum dubium (yellow form) I have sail >through -8 or -9'C without a >problem....... I....wouldn't be without the yellow dubium. " This is hardier than most places give, but far from the hardiness of North Temperate species. But what is this "Yellow" dubium". The Ornithogalum page shows a yellow hybrid http://pacificbulbsociety.org/pbswiki/index.php/… and the S. African Ornith page shows a yellow O. dubium. http://pacificbulbsociety.org/pbswiki/index.php/… as well as the yellow O. multifolium (and Ornithogalum graminifolium said to have yellow, white or pink flowers). Still wonder if anyone has tried to hybridize the S. African colored-flower forms with any of the white northern species. Is there some potential there for improved color in these easy to grown northern bulbs? Seems like there is a range of colors from orange to pink to yellow and my mental picture of these blended with white is very intriguing. Is this all a pipe dream or has anyone ever tried hybridizing within the wider elements of the genus.? Best Jim W. ps Sorry John, I'm not a fan of green flowers. Not an improvement over white.
