Amaryllis

I remember as a kid my Nan always used to have an amaryllis around Christmas. I remember because I always had to have my photo taken next to it to show how tall it was or how short I was   . I’ve grown a couple in the past. Really wanted to grow another one. So while Bob was collecting a miss placed order from Oban (don’t ask) on Friday. I got him to get one from Lidl for me.
It’s going to be a miracle if it survives the dogs tail or doesn’t grow so tall that it’s squashed against the caravan ceiling. 
Here it is      .

I’m measuring how much it grows each day. Yesterday it had grown 4cm. It now stands at 28cm. I think that’s a centimetre taller over night.

The other thing I’m expecting to happen. Is it to flower while I’m away for a couple of days the middle of next month. 
Anyone else growing amaryllis?
