Whats going on!

A few weeks ago I posted a blip of my Amaryllis with four beautiful flowers on, after a week or so they died off and I cut the stalk down and put it in a dark cupboard.

Yesterday I was looking for something in that same cupboard and found that it had grown again; the stalk was almost white but is darkening a bit after leaving it on the window ledge.
A friend of mine said she has never seen a Amaryllis do this; any ideas?
From a Host of Daffs I go to this lonely flower: part of the ups and downs of life.
Sad news last night my friend in Crosby whose husband is suffering from cancer which has severely affected his mobility, has now got a blood clot in his leg.

Much cooler here to-day and dull is the only word that fits; hope your day is better.
Cheers penny.
