Hi Barb,

it's done great in my garden since 2006. Some minor burn in the cold years but it bloomed in 2011 and looked great. It appears closely related to Yucca pallida but much larger............kinda like Y. pallida x flaccida? My Y. cernua was published in a German publication. Can you read German?

Yes, Tim is the only man who grows it and makes it flowering. Any seeds so far yet?
Barb, it seems like the ad shows the plant more blueish than truly colour. Ben Jenssen, Yucca Pollinator the Great (Tim, I mean Ben is number one in Europe, you are the Only One in North America) supposed 'it might a natural hybrid with genes from Yucca rupicola or Yucca pallida? More study is needed'.
Anyway it's always the fun discovering new stuff and trying to keep them going.

I noticed that immediately too...and Tim's has wider leaves. 😕

I can read German at the level of a 6 year old 😆 😆
Did you write the text for the article, Tim?
Man of many talents... 😀

Great pics, Tim.

I'm disappointed Plant Delights' photo is way off...

Can you read German?

Ich kann, aber bin kein Spezialist 😉

Great yucca, Tim. Frankly I never heard of it before. Guess it's never too late to learn 😉

It's worth a try for my zone. Great Yucca Tim! I just ordered seed from Mesa Garden.

the PDN photo looks accurate to me........I'm sure photo colors may be 'off' a little. The leaf color of cernua is similar to other Rupicolae Family Yuccas such as pallida, rupicola, rostrata, thompsoniana and reverchonii. Cernua reminds me of a Y. pallida on steroids since the leaves are longer and wider. Cernuas bloom stem is much more hairy than other Yuccas and the only other Yucca which is hairy like cernua is flaccida. That's why my gut is telling me cernua is some form of 'stable' hybrid between pallida and flaccida......just my guess.

Here's another photo of my cernua back in 2010 showing it's leaf width.
<img src= >

Don't forget we get 4" of precipitation every month............Yuccas tend to grow fast in my climate. If grown in dryer conditions the leaves my be a tad shorter/narrower.

I tried to get seed from Y. cernua when it bloomed but was not successful. 😥

Another note........Y. cernua is much more happy in my garden than Y. pallida, Y. rupicola and Y. reverchonii. Those three species barely survive here and I loose many since they are not happy (not cold damage). Many of the Rupicolae Family Yuccas are native to limestone areas with high pH soils. We have low pH soils. I need to raise the pH of the soil around my pallida/rupicola/reverchonii Yuccas to get them healthy.

Fore some reason Y. cernua does not require a high pH soil...........another clue in it's gene pool.................another clue that it may be a hybrid with Y. flaccida. 😕

PS.......here's the PDN photo of their cernua

That's it! 😀
I tried that...bombed 😆 😆

I agree the leaves look wide.
What really appealed to me was the very tidy shape.
And of course...the blue.

Thanks Tim.
Barb

I'm sure PDN took the 'best' looking photo for their magazine. Yuccas look different throughout the season and their photo is when it looked best. I noticed today the cernua leaves curl up when cold........kinda cool looking. 8)

This 'curl' could be another way to ID the genes in cernua.........I'll have to go around my yard to see which Yuccas curl up in cold.:lol:

Definitely one of them is Y. flaccida. If is Y. cernua natural hybrid, one of the gene donor is probably Y. flaccida, as you have mentioned earlier.

This yucca is available in Europe 8) Correction is available but sold out. This specialist Nursery was selling it

This is a special find for me as they have very rare Yuccas (when in stock) as well as Palms 8)

Quite the nursery, thanks for the link.
Do they put your name on a waiting list for new stock?

Listing some very nice palms...

Andy, I'm curious whether you need to get/pay for a phytosanitary certificate for shipping palms or yuccas in soil to UK from Germany.
Can't remember if we've discussed the topic previously as it applies to Europe/UK.

Barb

interesting that my Y. pallida does not have curled leaves like Y. cernua.

The only other Yucca which had curled leaves similar to Y. cernua is this Y. filamentosa/flaccida form.

Not all flaccidas curled as much as cernua. 😕

nice find Andy. Y. cernua is nice but it really looks like a large form of Y. pallida. The big benefit in my garden is that it thrives in low pH soils where pallida 'just survives' here.
