This is consistent with my experience. I have had Hipp seeds last for over 4 years in the refrigerator.

Not so. In April of 2022 I gathered a large seed pod from a randomly selected hybrid. It contained 45 quality seeds which I cleaned of chaff. I divided the seed into 3 groups. Using the "Float" method I had 14 germinate of 15 sewn. I placed the remaining 30 seeds in a ziplock bag in my refrigerator at 35ºF (1.6ºC). In May of 2023 I sewed 15 of the remaining, refrigerated seeds, again using the float method having 14 germinate. In May of this year, 2024, I removed the remaining 15 from the refrigerator and sewed them, with all 15 germinating. I just planted those and will grow to maturity. Well, refrigeration seems to preserve Hippeastrum seed quality for at least 25 months. Next, I will test seeds stored at ~ warm room temperature, 23ºC.
