Got my first one this summer from a top I cut off a store bought pineapple maybe years ago. Home grown, from my single example, has a more subtle flavor with hints of vanilla and much less acid.
Yep. The first one I grew last year had all of those notes, too. I got it started late and had to keep it under a grow light and heat lamp. It was ready in January.
I've just started on this journey. After a few false starts that died, I finally got one to root well. The plant is about 8 months old now and looks pretty happy.
Have fun on the journey! There are several ways to get it to flower if you don't want to wait, but I'd recommend giving it at least 2 years so the plant can grow big and strong first.
If you want it to flower on its own, I think this is the way to go. You can also cut up an apple or banana and place them around the plant (the gasses they give off will encourage it to flower), or drop a calcium carbide tablet into the middle of the plant with some water (careful when doing this).
