Hi: Wow! This is gathering momentum. Jim, you are right that it is against common sense that a bulb or corm could bury itself deeper yet they do, did and will probably keep on doing until they become extinct. MOIST soil is soft enough to let a powerful contractile root drag the bulb down. Contractile roots are broad, tapering, wrinkled looking and very distinct of the rather cylindrical fine absorbent roots and are capable of incredible effort. Almost every one in the forum will let you know of cases in which a bulb was thought to be gone only to find that the plant sprouts happily in due course. Eyrthroniums, Rhodophialas, Sternbergias and scores of others are capable of reaching depths incredible to bulb survival (in our opinion, the bulb thinks otherwise!).
