I am going to make an educated guess on your bulb. The flower reminds me of Supreme Garden, which was a sonatini type sold by Brent and Becky's Nursery several years ago. It was very popular as a garden amaryllis, since it was fairly cold tolerant: Dwarf, clumping, and evergreen. A photo of my clump of SG, planted in the ground, is in the NGA database. It has never fully recovered from being dug up 5 years ago ( to keep my puppy from eating it) and put in a pot. There has only been about a 10% blooming rate since then. Sonatini types can take a long time to establish themselves, before they bloom, and don't necessarily bloom every year. The pot is on my lanai, I keep it going and hope that someday I'll be pleasantly surprised to have lots of blooms. Don't let the colors of the photos throw you. Reds and Oranges are notoriously difficult to photograph. Depending on natural light and a camera flash, the colors can really vary.
