From the pic it looks like yucca elata but it is hard to tell.
I have one also and they are a great looking yucca.

It's hard to tell from the pic but it could be yucca glauca. They are more common than elata. They are both hard to tell apart when they are young.

They could be Yucca elata or Yucca glauca. It would be cool but we have many days of nonstop wet it just feels impossible.
In the photo it looks like there is some drainage protection.

We are having a zone 8a winter and some cordyline like plants are still green and alive.

Yuccaman,

Looks like what I would refer to as a common "spanish bayonet"....some folks call em soapweed?

When I bought mine it was tagged Yucca Glauca?

I've had mine now for 7-8 years and it is a beauty...I've removed the lower daggers and it has exposed a trunk..

Are there threads on the daggers?...

It loves a raised bed and...dryish feet....lots of rock around the base...

I think its called soapweed becuase the swords are so thin and look like weed grass but I really do not know much about that.

I saw some at connan nursery and the said spanish bayonet and below it yucca glauca. They would rarely get a trunk maybe better in warmer climates and its zone 4-3 hardy.

Are you meaning spanish daggers? I searched it but they have dagger posts in other topics. Sites like Gardenweb have alot of info on daggers, lots of posts about them. Or UBC Botanical Gardens.

A raised bed helps the water to drain faster and rocks help better. Most of them around here have that because it gets to way to wet, even for Yucca Filamentosas. Ones that have it do not tend to die back. If daggers did not have that they would rot and they are less hardy.

I tried my best

Yucca glaucas will grow in pretty much anything. They are about the hardiest yuccas around. They are actually called soapweed because the Natives use to pound the leaves with mallets or rocks to produce a foaming soap. 🙂

Jay....Thanks for clearing that up about yucca glauca 🙂

Nice pics Yucca man! That is a cool desert garden you have there 8) I hope your yuccas live a long time 😀

Thanks for helping me put an official name on it Jay...

The tag was right I guess?

I find the threads along the daggers/bayonets very unique....

Yuccaman, mine has trunked...I'll try and post some photos nxt while..

I think they might live for a long time in our brutal winters. 😀

Be happy to see those pics soon. Thanks for alot of help to. Thats my old garden I did 5 years ago

I moved away from it. I loved the huge tall pine trees that grew around. I did not know what yuccas
I was planting because they were given to me and the person did not know what they were.

Thanks everyone.

You've got them looking good yuccaman...

I've removed the lower daggers and neatened them up a bit on this one.....

Protection is a big thing...Being out of the wind and of course the drier the better...

The trunk is covered by about 8 inches of river rock...

No problemo guys. 🙂 Your glaucas are looking good. Now we all just need to find some y. elata x glauca for a nice tall super hardy trunking yucca.

Awsome pics 😀 Im hoping for my filamentosas to trunk.

Try a yucca elata or a yucca rostrata and Y. elata x glauca is super hardy they will do great as long as
they are dry in your zone.

Hope they get taller.

Hopefully you guys can help me out with a Glauca problem.
Last Early May, I went out west and dug up a Glauca from where they grow about 250 - 300 trees every 100 yards. This place is a vast, barron, dry, open area in Western Kansas, Eastern Colorado.
When I dug it up, I had to do it with only my snake cathing hook and couldn't dig all the way down and had to snap the root off about a foot underground. I put it in water and it stayed looking great while in the water.
When I got it home, I planted it in a place where I had previously had great luck with stuff growing.
However, after about a month of good heat and great watering, it slowley started to die off until there was nothing and it completly died.
Is the reason the root being snapped and if I try it again with a good shovel it will work? Or is it a matter of transplanting with these much like a Sabal in that you must cut off all existing fronds? Or something else????

Kansas it might have just been transplant shock. I have transplanted quite a few yuccas and it's happened to me before. Usually you don't need to get a lot of root for glaucas but maybe you didn't get enough. ❓ Some yuccas like elatas it's almost impossible to transplant when they are big because of the long taproot. When tranplanting yuccas i don't cut any leaves off.
