Possible Century Giant Plant? (Agave)

Spring, TX

What looks like two giant asparagus-like stocks are growing out of a plant in our front yard. I did a little research and thought it might be a Century Giant. I just wanted to get more opinions to find out exactly what it is. Right now, it's at least 7ft tall and it's growing pretty fast. We're not sure if we should cut it down or let it grow...

nope its a yucca ,not sure of which variety though

Keaau, HI

Might be Yucca glauca.

Calgary, AB(Zone 3b)

Yucca glauca doesn't normally have 7 foot flower stems. It's pretty modestly-sized, in the yucca world.

EDIT: Some closer photos, of both the plant, and the flower buds, would probable be helpful. Is the plant actually purplish in colour? It seems to contrast quite a bit from the other (obviously green) foliage in the photo.

Yucca glauca var. stricta is a larger than normal plant; but there are several other species with narrow leaves. Yucca glauca is widely cultivated.

Hmm, very enlightening... 1.8m flower stalks... I must get one and amaze the neighbors, LOL!

Thousand Oaks, CA

Looks more like Phormium sp.

Dublin, CA(Zone 9a)

No, not a phormium--the flower stalks do not match.
