Okay Judah... whoah here! All stop. We were trying to figure out what you had growing in the ground that sent out a bloom. The ones that have been there since you moved in? Those were the ones I was saying were Agapanthus... the Lily of the Nile.
Whatever those things are hanging off your fence aren't Lily of the Nile. Possibly Liriope. Can't even see them well enough to tell... but at your purchase price, Liriope is a good guess.
Agapanthus needs lots of water. Grows a good three foot high, flowers are gorgeous, grows from a bulb. Liriope doesn't. Liriope gets maybe a foot high. Flower stalks have negligible blooms, runs like crazy on rhizomes.
I would have LOVED to have you visit my water garden store.
