Most of the TURKS Cap Lilies will have Bulbils. And many of the ASiatics. Some produce bulbils at the junction of the stem and bulb just below the soil. Some produce Aerial bulbils on the stem near each leaf. Or you can pull off the "flakes" off the bulb itself and plant those. Which ever you have it is only necessary to plant them 1/2" deep. As the bulb matures over a 3 year period the roots will pull the bulb down into the soil to a depth enough to protect itself. I've had some "new" bulbs bloom with a single flower their first spring however it usually takes until the 3rd spring to grow to full size. If you let the lilies alone as they are they will do all the work for you. You can seperate as the mature.

lilium_guy, thanks for the explaination on bulbils. You sound like you have had a lot of experience with lilies. Maybe you can help me. I was cleaning out my fall beds today (a warm spell) and noticed bulbils surrounding my asiatics. They look like they are breaking through the soil and about to leaf up. Will they be okay through the winter if they start growing? Should I remove them and plant them elsewhere? Should I mulch them and hope they stay dormant? thanks

Usually, the term bulbils(i.e. aerial bulbils) is reserved for those that are produced in leaf axils (where the leaf meets the stem). Bulblets (more accurately stem bulblets) are those produced along the stem at or below the soil surface.

Using these definitions, bulbils are normally produced by relatively few types of lilies, whether they be turks caps or not. Bulblets are produced by most lilies, martagons being a major exception.

Semantics aside, lilium_guy's advice is good. Of course, if your bulblets are large it might be more efficient to plant a bit deeper. Use the "3 times the size of the bulb" rule. If a bulb doesn't have to spend energy pulling itself down, all the better. The link given above has lots of good info on propagation, including lilium_guy's flaking (more commonly called scaling).

jensyen, don't worry. Those bulblets will be just fine through the winter, even if they start growing now. The ones I see right at ground surface, exposed to the worst the winter can offer, do just fine. I don't mulch. As lilium guy advised, leave them alone, dig and divide when the bed gets too crowded (every 2-3 years here). They'll take care of themselves until then.

Thank you all on the great info!
