In the crinum lily world, a yellow flower is considered the holy grail by plant breeders, since it only naturally exists in the Australian crinum species, Crinum luteolum. Two other species which occasionally show a yellow blush in the flower are Crinum bulbispermum and Crinum jagus. Crinum luteolum is completely ungrowable in the Southeast US. Consequently, we must find yellow pigment from the other two species.
Many years ago, a secretive California crinum breeder distributed a fuzzy Sasquatch-like photo of what was supposedly his yellow flowered crinum, derived from a white-flowered Crinum bulbispermum. The plant itself has never been seen in person, despite assurances from the breeder that it still exists. In 2008, the breeder agreed to sell us seed from his parent plant, with the caveat that it wouldn’t look like the parent.
Below is the best clone that we selected from our first set of seedlings from Crinum ‘Yellow Triumph’. As you can see, the flower is virtually all white, except for a chartreuse green base. Since it was a nice flowering clone, we gave it the name Crinum ‘White Swans’.
Since 2008, we have repeatedly self-pollinated our original seedling selection, each time selecting those offspring that showed the most yellow color. Over time, the best seedlings were crossed with each other, and the selection process continued.
Fast forward to 2023…15 years after our original seedling flowered, we finally have plants that are showing a decent amount of yellow in the flowers. The yellow shows best as the flowers open in late afternoon. Below are two of our best 2019/2020 seedlings. While these aren’t yet a finished product, we are seeing the proverbial gold light at the end of the long tunnel.
