Interesting, it does look like 'Yelloween' is somewhat variable in height. This lady here grows 'Yelloween' quite tall:

Sometimes one does wonder why a lily grows the way it does. After three years I finally gave up on the OT 'Lavon' after getting it to grow to the not so impressive height of 1,5 feet
. OK so the bulbs I got was absolutely rubbish, extremely dry with huge sprouts, but still they should have been able to grow taller from scales faster than that
