Just from the fact it's planted in a neat row leads me to believe it isn't a weed. The thick leaves look like some type of bulb - where are you located? Also, have you seen any flowers?

Florida. And no I haven't seen any flower. It's listed at a house I am looking to purchase so I haven't spent very much time around it

I'm out of my element in FL. Hopefully someone can chime in. :)

Since it's a row of bulbs it's highly unlikely to be a weed. There are several possible candidates. Crinum, amaryllis, agapanthus....

Looks like Hymenocallis. Mine always burst into bloom after a tropical storm or a few days of heavy rain and the soil gets soggy.
