Those Lachenalias are easy, they're a South African bulb, a genus including some 90 species, planted in Autumn(Fall). Frost tender but this is why I pot them, you can put them somewhere protected from frost or snow.
I never put seeds into the ground, because I've lost them also, though certainly not to squirrels. LOL. Probably mice. I always put them in punnets and plant the seedlings later instead. So satisfying, and very cheap. You can have a glorious garden for little cost if you use seed.
DD, go for it in the Fall. I can imagine how nice your hubby's geraniums are. I've virtually just started collecting and growing them myself. Very colorful and cheery.
