That would be the easy explanation, but I don't think it would be the case. Each of the higher count flowers was about 30% larger than when grown in dry clay, and with stems double the height. I am wondering if it is an age maturity thing.
For anyone interested in species, an interesting note:
During the time L. majoense grew in the clay soil, there was a summer in which there was a long moist period (3-4 weeks) right at the time it would normally be the driest. Growing in the same soil, L. taliense and L. primulinum bulbs rotted that summer, but L. majoense was not affected.
