Dear Steve and all; Very interesting post. I don't have exactly as you have-watered-versus unwatered for comparison. We have had even more drought though so I think I can give other examples. I have a row of approximately 25 L. chinensis and 25 L. squamigera (not mixed). I get multiple stalks from each bulb regularly. So far this row has received only an occasional random hand sprinkling and produced only three (total) 4 inch stalks on L. squamigera, none on chinensis. In a slightly moister part of the garden, 2 small trees are surrounded by a ringed Lycoris bed again about 25 bulbs each of L. squamigera and L. caldwellii. The squamigera has produced about a dozen foot tall stalks and the caldwellii has produced none. I recently watered both so ... we shall see. L. caldwellii is a later bloomer so it might still catch up I am getting the same results as you if more extreme. L. squamigera is very common around the metro area and great clumps are in bloom in typical urban and suburban landscapes especially where the lawn is watered. Seems to be normal in size and number. This sure suggests that water is not the prime 'key' to initiate bloom, and at a continuing high temp (over 100 for a week), the onset of cooler fall weather isn't likely either. So what initiates bloom in Lycoris? Some internal clock? A call from Alabama said they expect L. radiata to bloom on or by Sept 7 every year like the swallows returning to Capistrano. Earth's magnetic field? The moon's influence? Anyone's guess. Back to the drawing boards Jim W. -- Dr. James W. Waddick 8871 NW Brostrom Rd.
