You for sure have some very challenging weather conditions and I'm very sorry that you suffered so many losses in the garden
A few years ago I received some OT lilies that were in very bad shape and some of them produced a huge amount of stem bulblets.
Many other bulbs are also prone to break up and divide when exposed to stress. For instance if one wants a lot of Tulip bulbs quickly one can plant them closer to the surface and then they tend to produce many small bulbs instead of fewer larger ones.
