Black seedhead

Dear All,
Most of you will remember the Black seedhead of Brook Ager
pollinated by a Bumblebee that I posted last spring.
I have attached the picture if you have forgotten.
I obtained 14 seeds from it and today I noticed 1 shoot of 2″ in length in
the pot while moving my seedling pot to a new location at the side of the
house.
This is showing very early here in the UK as I would normally expect to
notice growth in December or January.
Is this another step toward the Black Narcissus!
Keep smiling,
Ian
