These interesting bulbs came from an eBay seller possibly twelve years ago. What has been interesting about them is that they don’t really thrive in the greenhouse, but they reproduce anyway through offsets. So, I’ve had up to a dozen pots of them in the past, but I am probably down to five pots now. Usually one or two of the bulbs seem to be doing well and getting several leaves and building up mass–teasing me into thinking that maybe someday there could be flowers. But in twelve years, no flowers have appeared. I’ve asked the Pacific Bulb Society members for suggestions, but their suggestions and the online resources haven’t solved anything for me.
My 2020 plans for these plants are to top-dress them with lots of fertilizer mixed in and to move them outside in the spring in bright light to hopefully ripen off the bulbs and get stronger, bloom-ready plants.
