They are leaf axil "bulbils" (vs. "bulblets" found along the underground portion of the stem and at the side of the main bulb). If you let them get ripe and then plant them, they will produce more lilies. Search the site for that phrase and you should get a lot of "hits".

I collected a handful of bulbils (with the owner's permission, of course) from a stand of orange tiger lilies (L. latifolium type) that I passed on the street one day a few years ago. Planted them and this year it looks like I will have my first flowering size plants. But, they have been making more bulbils all along, and now I find little lily plants growing everywhere (filled with more bulbils) in the yard - I think the squirrels must move the bulbils around, plus wind and rain and whatever. Cats and rabbits have nothing on bulbil-producing lilies.....

Thanks so much! Of course the first thing I found when I looked for problems on this forum was evil red beetles so I panicked. I had no idea the lilies would make bulbils before they made flowers. I'm looking forward to lots more lilies eventually.
