10 Cultivars Listed
A new introduction, Arctic Bells is a bulbocodium from Walter Blom. It is classified as a Yellow-Yellow, but it is more of a white flower, in the way that White petticoat is white. We were surprised to see the seed parent is the perfect bloomer “Border Beauty”, picture attached. Who would think of that ?
Mary Poppins is a platinum blonde with pale silver-yellow blooms that are tough and long lasting as a strict governess. Strong grower that can increase rapidly. Mary seems to tolerate Zone 6 but is probably happier in Zones 7 and 8. Dwarf and miniature
The bulbocodium you will most likely find today in the commercial trade, Oxford Gold was widely adopted by large growers soon after its introduction, A robust grower with an upright habit and full on chrome yellow color. Perhaps Oxford gets its virility and fragrance from its species Jonquil pollen parent. Probably not a miniature, makes a large bloom and plant for a 10.
White Petticoat is recently registered, but I consider her to be the standard bearer of white bulbocodium cultivars, rounder, smoother and a little less petunia-flowered than cantabricus. If you want to wake up on a fine spring morning to a sea of happy white hoop faces in your garden this is the one to make it so. Said to be fragrant, but when petticoat blooms for us it is cold and the ground is so very far away from our olfactory nerves. Many bulbocodium enthusiasts grow this division in pots in the greenhouse, that's an easier sniff laboratory.
