First time I've seen it. I've got 3 or 4 in the garden and one is starting to grow flowering branches.

Photos tomorrow when the light is better.

Not growing straight up but quite a few sprouts growing with obvious flower buds.

Edit.

I started with one plant and when it got tall I chopped the top off and stuck the top in the ground, a few times and they've all rooted and grown ?

Couple of photos this morning now there is enougb light.

So this IS a Yucca and not an Agave? Asking because it doesn't look like the Yucca filamentosa that I know and have never seen here.

Not a plant expert just remember buying one in a pot a good few years ago that said yukka plant. It grows fast and every couple of years I cut one of the side sprouts off that grow when you lop the top off. All of rooted quickly and grew.

I didn't even know they flowered until I saw it last night. After a google closest picture to mine I can find is the one below.

Would love to find one like the second picture.

This is the 'parent' plant all the others came from.

Home work for you. Let us know if you determine the species ID.
