I don't cut my yucca flowers, either.

This year my Y. linearifolia is flowering spectacularly. last time it flowered the crown divided and it grew two equal heads. This year double flowers!

I can't imagine cutting off a Yucca bloom.........especially a rostrata bloom. How are rostratas blooming so small in your climate? Are your Yuccas really rostrata? Do the leaf margins have a fine serrated edge? They seem like a different form from the two I have. Never a bloom on mine since I received them in 2002.


Strange you should say that, the leaf margins seem smooth on mine?

I think Andy may have alluded to why it's flowered so young. Despite the way it looks the rootball was smaller than I expected when I planted it, so a combination of this plus transition shock has probably lead it to flower.

Here's an update.

Paul, great looking double bloom! I hope you try to hybridize her.

Phil, some rostrata forms don't have a serrated leaf margin, but many/most do. People who live in Texas say rostrata doesn't bloom until 6 feet (2m) tall. I've heard many times a transplanted Yucca will bloom. This happened to me with a Treculeana back in 2003 after receiving it in 2002. Keep the bloom Phil and try to pollenate the flowers. If we can see a seed pod we can identify the Yucca. My gut says your Yucca may have some linearifolia genes. Rostrata seed pods will be erect while linearifolia will be pendant and fleshy.

Andy, treculeana x linearifolia and opposite cross would be amazing hybrids. Please try to hybridize!

I'm trying to pollenate my Y. gloriosa/recurvifolia 'highway 421'. This unusual form is supposed to produce erect seed pods. It may be the hardiest form of gloriosa/recurvifolia in my garden. Many forms were killed above the snow line during the winter from hell (2014-2015).

Yucca cernua is sending up three blooms.
Image

Yucca filamentosa x rostrata form #1 Benny Jensen is sending up another bloom, three years in a row. What a great hybrid.

Haha Kev, it looks good in the glass!

The treculeana looks good Andy but it seems your linearifolia is going to hit the roof. The schottii you kindly sent me is going great guns this year too.

You have some great looking hybrids there Tim, I bought a few from a German site last year, elata x thompsoniana and pallida x kharlsruensis both are doing OK if a little small at the moment. Unfortunately I don't think I'll be letting my rostrata run to seed (it would require hand pollination as far as I can tell) as I want the head to have some recovery time before winter and need to ensure its roots properly. Maybe next time.

Thanks all :-)

Tim... I have tried some pollination with another Yucca possibly Torreyi. If the Linearifolia flowers open in time I'll attempt some more :D
Regarding Phil's Rostrata... it looks pure Rostrata to me. We now have Spanish imports that are more vigorous being field grown and look much nicer than their natural counterparts in Mexico. The market is awash with them in Europe.
Phil.... glad your Scottii is growing well. I was after this specimen but they won't ship to the UK... another Spanish import on steroids :lol:

That's quite a plant! Not cheap though, I bet you'd be looking at neck end of £1000 delivered if they shipped. I thought I'd done well buying a couple of small hybrid yuccas from Germany, how do you come across all these obscure websites!?!

Phil I blame this on you as I have another Yucca linearifolia flowering now.
2 days ago I did not see anything they just seem to sneak up on me while I am watching the football

Linearifolia seem to flower well in the UK and yes like Kev I have another Linearifolia flowering in the covered area. This yucca is in a state of flux and after nearly forming two heads last year is flowering again as well as sending out two new shoots from the roots

Eeeek! Sorry Kev :oops: :oops:

No signs on either of my linearifolia although one was new and the other was transplanted last year. The new one, which is supposedly "Galeana", is sending a pup up from the base as is my queretaroensis hybrid.

Nice trunk forming Kev. My gloriosa posted above is pushing up a trunk as well.
