Yucca gloriosa/recurvifolia 'highway 421'

Don's 'highway 421' Yucca is going to bloom. This has proved to be one of the hardiest Yucca gloriosa/recurvifolias in my garden as many forms died above the snow line in the 2014-2015 winter.

Wow! another hybrid? I'm about to start pollinating my filamentosas (practice, practice)and hopefully in the next couple of years I could have my glaucas bloom...

Yucca 421 is the only gloriosa/recurvifolia form in my garden with erect seed pods. Glauca Are shy bloomers in my garden.

Hey Tim, Mine bloom a couple of months earlier. Am thinking that we decided it was a recurvifolia because of the erect fruit? A shame the leaves don't hang like the regular recurvifolia. I like the blue color though. My aloifolias are starting to bloom and the aloifolai arcuata and gloriosa won't be too far behind (August)

Hi Don! 421 leaves are more like 'gloriosa' but pods are more like 'recurvifolia'. I really believe all recurvifolias and gloriosas are hybrids between aloifolia and filamentosa/flaccida. If you need some pollen for your upcoming blooms let me know. Hybrids with aloifolia as the pollen parent are very rare. I have 'constricta x filamentosa' X 'filamentosa x elata big mama' blooming, filamentosa x rostrata, and many more.

Tim, I'd take you up on the pollen but I have never successfully pollinated a yucca. Am with you 100% on the origins of recurvifolia and gloriosa. Recurvifolia being aloifolia x flacida and gloriosa being alifolia filimentosa concava. I know that concava is now the variety used to define the species filimentosa but there is a lot of variation on concava as we know. The New Jersey and Delaware ones are not very similar to ours here along the coast in N.C. The latter having very erect boat shaped leaves.

Don, do your native filamentosa/ concava have constricted seed pods where the middle is narrow?
Posted by Don on July 26, 2016, 3:07 pm, in reply to "Re: Seed pod"
Tim. The concava type is inflated and the filimentosa type is constricted like a peanut. Made a pdf a few years back for comparison and have converted it into a jpeg to post here (hopefully)

Great photos Don. Interesting that your concava seed pods aren't constricted but the other form is. Our small forms of filamentosa which have naturalized up here have 1" (2.5cm) seed pods which are highly constricted. What forms of filamentosa in your area have small pods (1") and are constricted? I always ID'd them as a form of concava.

as you can see by the CM scale in the pic our seed pods are much larger than 1 inch. Am guessing that the concava morph is variable along latitude. The southern form is also more erect and symmetrical in my opinion. We lived in the Pine Barrens of NJ for 14 years and never saw any concava that weren't sloppy looking.

Yes our 'native' form is not the true concava but seems to be closer to concava than other forms. Here's some of those small seed pods from the Coventry, RI colony

Have never seen anything like those here or in NJ Tim. The leaves terminate like irises instead of the boat shaped termination I'm accustomed to in our NC concava.

Don, you've never seen pods like this? I wonder where their source is from? I know of several areas where these small podded, constricted seed pods are from. I always wondered if these were 'native' since they are unusual. I also think Yuccas were traded by the native Americans and perhaps evolved up here over time.

Tim, It is difficult to say what is native with yuccas. Personal observations would suggest that they are usually found along roads and near dwellings. They certainly seem native at or near the beach and on coastal sand hills. The pods in your pic are small and extremely pinched in the middle. I really haven't been around much to observe yuccas so this could just be the northern extreme of the concava morph. the leaves of the RI plants look different also. Here is the local concava leaf morphology.

Tim, that's great news! how old is your specimen? also between this gloriosa & your Tennessee gloriosa which one do you think is the most cold tolerant? regards

The Tennessee gloriosa survived that same winter. Tennessee gloriosa is very Hardy too.
