Also called Mother in laws tongue. I'd love to see more of to know for sure that it's S.trifascata, but it sure looks like it from the top. Is it tall? Or short and squatty?
If it's short, than it's Bird's Nest Snake plant, and I've never seen that one bloom…

Oops, just clicked the pic. and it does look tall…Sorry.

I thought I had a better picture, but I couldn't find one. The leaves are tall -- anywhere from 12 to 18" high, It isn't low and squatty, I do know that! I have seen these plants all my life and this is the first time I ever saw one bloom!

Isn't it great!?!? The only ones that bloom for me are those that are outside.

This one had been outside all summer and I was surprised when I saw the blooms, so I brought it inside, as we do have frost sometimes in DeLand.

Yes, and I'm even further North. I have some in the ground that have survived several winters so far, but it is a sheltered area of the yard…Gotta love those micro-climates!

Jean: It sure looks like: Snake Plant (Dracaena trifasciata)

I've heard it can be invasive if grown in the ground here in Florida; I find it to be fairly cold hardy, mine were all grown in containers but would stay outside year round. I left a few pots at our other house for our tenants and gave some to the neighbors when we moved. I had one bloom during the winter a few years ago.

Cool! Be sure to get a good sniff!! It should smell heavenly, and be strong enough to overpower a small room. I've seen a bloom twice, having had this plant for about 20 years.

@plantladylin I have found that just about anything you put in the ground in FL can become invasive.
