Dug out already:

Check out these roots:

Covered and ready for incoming winter 8)

marceli,
your weather sticker says 12C; I'd pull the plastic up high and tie it so the yucca is protected from rain.
Too warm to enclose it in plastic now, I think.

You can't see from this perspective, but I made two "windows" on both sides to improve ventilation and protect them from cooking 🙂 Should be enough I guess.

nice Yuccas. You have some cold temps. I'm not sure on the ID of those Yuccas. When they grow up a little more I'm sure we can ID them for you. Do you have a few close up photos of the unknown Yuccas?

Tim, this is the closest photo I got atm:

Do you want me to take pictures of leaves and already forming trunk? I can crawl under my teepee and do that 😀

The unknown Yucca is still not 'mature' so it's ID is difficult. If I had to guess I would say it's a Y. arkansana but it could be other species like filamentosa, flaccida, a hybrid or less likely constricta.............possible others??. I don't see any glauca in it. A bloom would help very much.

According to bennyskaktus.dk Invalided published name of arkansana is Yucca glauca var. arkansana. Might be the reason why sellers sell those as glauca 😕
Judging from this picture: it might be Y. arkansana, but are they really so hardy? Time will tell I guess.

Time will tell I guess.

I think it will live. 😀

Hi Marceli,

I was just looking at the roots of the Yucca you just dug up. Is this the 'unknown' Yucca? The roots are not of filamentosa or flaccida. The roots are more like a western Yucca like glauca or elata........but the leaves are wide unlike glauca or elata. I bet you have a form of Y. arkansana.

Y. arkansana blooms can be 'racemose' like Y. glauca. I bet when your 'unknown' Yuccas bloom they will be 'racemose'.......this is why the seller called them Y. glauca. A 'racemose' bloom has little to no branches on the bloom. Here's a photo of a Y. arkansana in my garden to show you a 'racemose' bloom.

this Yucca arkansana has intermediate width leaves which are wider than glauca but narrower than filamentosa.......the bloom is more like glauca.

Yup - this is one of my unknown yuccas! I have a feeling you solved the mystery, but we need to wait until it blooms to be sure 🙂

Today's pictures. Temp. -11C 8)

Uknown yucca:

Y. Elegantissima (probably)

Y. baccata:

Y. gloriosa / recurvifolia:

your Yuccas look nice and warm in that protection!

marceli, the unknown yucca wants that plastic hole fixed 😆

If it gets a lot colder, will you add heat inside?

Barb: my yucca's too young to vote, so I'm in charge 😉

I'm not planning on adding any heat, so it's do or die 😈
