Not sure if this should be under Nomocharis but apparently the taxonimists think otherwise. Several years I tried crossing it with Nomocharis but I was unsuccessful at all attempts.
Last year I was very worried about this clump of what I grew as Lilium oxypetalum v. insigne. In the autumn of 2009 I transplanted them and what was an unusual colour pattern disappeared completely. See Lilium 2010 thread at about this time last year. This year they appear to have settled in and the vigour is back along, the colour has returned to its usual.
