It's an old, established trick among some growers of martagon lilies (i.e.
Lilium martagon and the species closely related to it, not all of which
have the martagon flower shape) to allow a seed pod to develop in order to
keep the plant green longer. In our climate, martagons typically die down
early - sometimes in July, and a seed pod will prolong the life of the
annual stem.

Montgomery County, Maryland, USA, USDA zone 7, where we are on the fringe
of martagon country.
