Man oh man, Tim, you're one S E R I O U S yucca lover :D
Wonderful tour of your place.

A few things struck me right away (other than the obvious beauty of the specimens).
1. "coarser" leafed yuccas are less hardy?
2. the speed of growth since grown from SEED, some in only 6-10 years, and TRUNKING!
What is your secret????

The 10 foot spike/blossoms, have never seen any THAT tall. wow.
Or 37 inch long leaves.

I'm going to go kick my yuccas :|
Thanks for those great pics Tim.

Tim

What a great collection,I really enjoyed your pics!

Looks like a Saguaro in there too,to bad they are not more cold hardy.


How is the Monkey puzzle tree doing now?

Hi Barb,

I'm in USDA zone 6b....is that the same as Canandian zone 5b? If so, we are in similar climates. We get a lot of precipitation (about 4 inches or 10 cm) per month, every month of the year.

Yuccas (bigger specimens...not seedlings) which I've tried and didn't survive include:
Yucca aloifolia (many, many, many, all 5 gallon or so)
Yucca torreyi (5 gallon size)
Yucca treculeana (2 forms, both with 1m tall trunks)
Yucca rigida (5 gallon size)
Yucca baccata v thornberi (1 to 2 gallon size)

I haven't tried a big Y. brevifolia, Y. faxoniana, Y. carnerosana or Y. schidigera yet. I've tried smaller seed grown plants and all died. It appears we get too much winter moisture for the south west trunking Yuccas.

The only trunk forming southwest Yuccas which have survived in my climate are:
Yucca elata
Yucca schottii (for many years prior to dying).

No secret on Yucca growth....I guess it's all the rain we get?

Yes, those Yucca constricta x filamentosa hybrids have really tall blooms. Yucca constricta has one of the tallest blooms of all Yuccas....this is where the trait comes from.

Hi Jim,

yes I have a few Saguaros potted up from 1992 seed.

The Monkey Puzzle tree was planted in 2006 (seed grown from 2000) and did burn out every winter for me but keeps on living. This past winter 2009-2010 I constructed a mini green house over it and placed x-mas lights inside. It remained green!

I believe USDA zone6b is still at least "one or two better" than Cdn 5b.
Longer duration of cold, far far less precip than you.
We're in a rainshadow of a rainshadow (yup), and receive anywhere between 10 and 13 inches of precip ANNUALLY.
Hot dry desert air mostly (now that the heat has arrived).

Paul (from Canada) will soon see your yucca pics, and he'll flip.
He's tried many many yuccas unprotected during winter and has some good info.

That's quite the list ($$$$) :lol: :lol:

Growing yuccas unprotected--and maybe even a joshua tree--was for me the only bright side to global warming er...a... climate change.

Here's my little joshua:

Thanks!

I wonder if yours may be Thompsoniana Barb,
are the edges of the leaves like a hack saw blade or smooth?

Hi Barb,

I'm not familiar with Canadian climate zones.....USDA 6b has an average low of 0F to -5F (-17.8C to -20.6C). Are you much colder than that?

If your dry, you can probably grow some of the southwest trunkers like Y. elata, Y. schottii, Y. faxoniana, Y. thompsoniana, Y. rostrata, and perhaps Y. torreyi. Give it a try.

Your 'brevifolia' really doesn't look like a brevifolia as Jim mentioned. I rarely get to see mature brevifolia specimens here on the east coast. Your specimen cleary has some filaments along the edge of the leaf. This trait alone 'weeds' out many Yucca species. I don't think brevifolia has filaments....if they do not many at all. Brevifolia also has a fine serrated leaf edge. If you run your finger along the leaf edge you might get a paper cut!

I can't ID your 'brevifolia' Yucca by that one photo. Do you have another photo? That Yucca may be a form of harrimaniae or angustissima (just guessing at this stage). I'm not too good ID'ing these harri's/angusties unless they are blooming since they don't like my climate and either die (not from cold) or struggle/look deformed. Perhaps someone from the Utah area can ID this one for you.

How much direct sun (outside) does this Yucca receive....my impression is that it does not receive much or perhaps it's been containerized for some time. My experience with growing Yuccas in containers is.........don't. They hate it. They will grow for 3 months then virtually stop. I try to get seedlings in the ground asap and protect them from critters/winter. They grow so fast in the ground.

smooth, no teeth.

Found the temp records, which indicated a WARM winter for us (yup!)

Cold started around Dec.6 at -12C (10F).
Coldest night was Dec.14 -20.6C (-5F).
Rest of Dec slightly milder around -10.2C (13F) on the 28th.
One day Jan.7 saw -12C, then improvement to near zero most days.
Hardly any snow this year, so plants had very little protection from cold NW winds.

Nope, no papercut from the "brevifolia".
But the underside of the leaf felt rougher than I remember.
I think last year Paul said he thought it was something else, too.

So that's what's wrong! I've got the yuccas mostly in pots.
Wanted them to get larger to improve chances for winter survival.
But they haven't grown.
And then I look at your pictures...from seed 6 to 10 years ago, and the beggars are gorgeous, trunking, and blooming.
I'd have more luck growing ROCKS.

They're in the sun for most of the day, "hotter than Haiti" on this southslope.

Here's a close-up of the "Joshua" leaf from last year.

...back to watering my "no name" plants. :lol: :lol: :lol:

Thanks guys!

Hi Barb,

your too funny! (I'd have more luck growing rocks).

I'd get those Yuccas in the ground in your sunniest position.....and water them every few days from May through August. If your temps remain warmer than -22C (dry climate) you'll be able to grow most Yuccas native to the USA. Only Y. whippeli, treculeana and aloifolia may perish. Who knows.....maybe even treculeana & aloifolia could survive a super dry -22C?

Your 'brevifolia' is likely from the glauca, arkansana (narrow leaf forms), harrimaniae, or angustissma species. A bloom will certainly ID it.

Sheesh, I hadn't intended to hijack your thread.

I'll back off and let others enjoy YOUR yucca pics. I'm still drooling over them.

Thanks.

Hi Tim,
I see some filamentosa x elata hybrids I would love to have and some other very cool yuccas. Very nice garden! :shock: 8)

Tim,
Everything has really perked up since I was last there in April or so, like wise I need to make a trip over to your place soon.

I just called that guy who has the Eucalyptus so maybe it will be sooner then later. Hopefully he'll call me back it would be fun to try them.

Looking great!

Hi Tim,

Welcome to the forum! I believe, I've seen your work on, yucca expert, Benny Møller Jensen's website? Very cool to have you on this forum!

Wow, what an incredible collection of yuccas! :shock: Amazing variety. I'm especially intrigued by your hybrids. Until now, no one on this forum (to my knowledge) has grown any kind of hybrid. I'm really impressed too, by your successes with trunking western species rostrata and elata. They all look great!

Tim, is there any chance you'd be willing sell me some seeds or plants? I'd be especially interested in your elata, glauca, and filimentosa hybrids. I'm a budding yucca enthusiast myself! In my zone, glauca and filimentosa are proven hardy. I'm experimenting with several other species though, some of which, will require protection. Check out my desert garden if you have a chance:

Thanks and great work!

I just got back from a mini vacation in New Hampshire. Thanks to all for the nice comments.

Duncan& others, I have some seeds I can send you from some hybrids. You can plant many and select the 'hardiest' forms. You'll have to give me your mailing address.

Aaron, funny that the Y. glauca x filamentosa has never flowered for me. It was seed grown from 2001 seed. I'm sure once it flowers it will send up some pups......one will have your name on it! Here's the same Yucca in June 2004 when I moved to Massachusetts and just created my garden bed. It's located in front of the Echinocactus (horse crippler) and Yucca rostrata:
