Progress of the pineapple

About one month ago when I was getting ready to give my pineapples their summer trip outside I noticed that three of them had started to send up flower stalks.  These were pineapple tops that we put into the ground about one year ago. If you look you can see the small scales forming, but it is a long process.

 





 First discovery you can just start to see the stalk...

 









Little more progress but several side shoots, didn't think it was supposed to do that.  I though they only produced one stalk per plant...

  There are three tops in this pot and two have flower stalks.  Most of the tops are 2-3 feet tall when they start to fruit.  Some of the leaves are smooth and some are serrated and hurt if they poke you. The newest stalk looks very different from the others.  It may be another variety, the leaves are serrated.
