Yucca cernua

Gorgeous pic in the Plant Delights brochure. http://www.plantdelights.com/Y/products/817/
Interesting that it may make it in zone 7.
Would like to try it...in 5b, 6a

"We are very pleased to offer a new species of yucca that was recently discovered by plantsman, Eric Keith, and subsequently named in 2003 from a few small populations (less than 2,000 plants) in Newton and Jasper Counties in east Texas. In the wild, Yucca cernua occurs on acidic clay soils in open piney forests. In the garden, our 2009 planted specimens have made lovely, solitary, 2' tall x 4' wide rosettes of glaucous foliage. When mature, the clumps are topped with dramatic 10' tall flower spikes of large white bells. After flowering, the clump often produces additional basal rosettes. Yucca cernua is a US Endangered/Threatened candidate, which, if adopted will limit distribution, propagation, and free market access via the "government knows best" philosophy.
Pot Size: 3.5" (24 fl. oz/709.77 ml)
In Stock
Zone: 7-10, possibly colder, Height: 24", Culture: Sun to Part Sun, Origin: USA
# 9873"

darn...image didn't work!

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?

A few photos.

Hairy bloom stem..........a Y. flaccida trait.

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...

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=http://i30.photobucket.com/albums/c309/ ... AM0584.jpg>

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.

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.

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.

Henoh_Croatia · Post by **Henoh_Croatia** » Wed Jan 23, 2013 1:48 am

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

Correction is available but sold out. This specialist Nursery was selling it
http://www.microsofttranslator.com/bv.a ... c-20-30-cm

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

lucky1 · Post by **lucky1** » Wed Jan 23, 2013 1:36 pm

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.

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

Yucca pallida at 12F
<img src=http://i30.photobucket.com/albums/c309/ ... D4A426.jpg>

The only other Yucca which had curled leaves similar to Y. cernua is this Y. filamentosa/flaccida form.
<img src=http://i30.photobucket.com/albums/c309/ ... 546AC3.jpg>

Not all flaccidas curled as much as cernua.

TimMAz6 · Post by **TimMAz6** » Wed Jan 23, 2013 1:56 pm

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.

Barb.... No there is no restriction on movement of plants in Europe. I remember getting a Butia Eriospatha from a UK dealer who in turn got it from South America. After it was killed in the 2010 Winter I dug it up only to find the roots suffocated in what can be described as red concrete... probably happy in it down there but not here.
Haven't tried to order yet but I'm interested in the multi palm order.

Oooh, I'm so jealous Andy.
Let us know what you're ordering...living vicariously
Guess you've found some more space...

We Canadians are so screwed by "the system"...no plants ever make it with soil.
So plants arrive here bareroot... crispy...and stone-dead.

Very nice Tim.
My filamentosa are just sending up a flower stalk.
The yuccas in town aren't that far along yet.

You're probably a couple of weeks ahead from your warm weather and rain.

Looking forward to seeing all those gorgeous blooms.

we got another 4 inches of rain last night.........it's moist here.

Barb.....please post some photos of the blooming Yuccas in your area.

Tim very beautiful yucca whether it is possible to obtain seed

lucky1 · Post by **lucky1** » Tue Jun 11, 2013 11:08 am

post some photos of the blooming Yuccas in your area.

Tim, will do.
They all seem to have put on the brakes with the recent cool nights.

4 inches of rain in ONE night?

I can't even imagine what that's like.
We had 4 inches over about 5 or 6 days.
And I thought we were going to have to build an ark.

Hi Barb,

I'm sure your area could use the rain since you don't get much?

We are up to 9.32 inches (23.67cm) for the month of June.......it's moist here.

Here's an update on Yucca cernua:

Incredible height on that flower spike, Tim.

Wow!

Henoh_Croatia · Post by **Henoh_Croatia** » Sat Jun 22, 2013 12:47 pm

Good looking Yucca. I have one seedling of this species from Mesa Garden. Tim, your blooming Y. cernua is the same mother plant that bloomed two years ago, or sucker?

TimMAz6 · Post by **TimMAz6** » Thu Jun 27, 2013 6:00 pm

Hi Henoh,

I think the cernua bloom is off a 'new' offshoot. I'm not sure though.
