My Amaryllis

A friend gave me this amaryllis just a few weeks ago (Maybe 4 weeks?) It was just starting to show a little green coming out of the base. I had never had an amaryllis before and had no idea how quickly they grow. Was starting to feel like we were in the Twilight Zone! This first picture was taken about a week after she gave it to me.

This was taken about 3 days later.

 Measured from the top of the pot because my measurer wouldn't fit in close to the base.

This was 4 or 5 weeks after I got it. I have never seen a plant grow so quickly in my whole life!
