Hi, Tim! I sincerely apologize for taking an eternity to respond to you. I would say that, based on the conversation, Michigan has both flaccida and filamentosa forms in the wild. If I were to guess, I would say that the locality determines the form. Some folks would argue that certain plants have naturalized from garden specimens. This is due to the fact that the little yucca moth is present throughout the entire state of Michigan, and that same moth pollinates filamentosa, flaccida, glauca, &c. So pollination and propagation occur naturally. Because the glaciers have come through here some many thousands of years ago and scoured the surface of the land, it is impossible to say what is native and what is naturalized. When I see folks argue about this online, I ahve to laugh to myself. We have only kept a history of a few hundred years! And the loggers erased the land in those few hundred years, changing the landscape and causing wholesale extinction of scores of species of plants and animals (both terrestrial and aquatic) in the process. Best regards and happy gardening, Miguel aka Mike
I'm not Mike, but here are his photos from the pods and Seeds
and here the constricted pod, that Mike had sent me. In the constricted part of this, the yucca moths had all seeds eaten, unfortunately.
Perhaps it is similarly as in the Opuntias there, that standing morphologically between O. compressa - East and O. macrorhiza - West, or as the intermediate form is referred: Opuntia (aff.) cespitosa.
Mike referred this wild Michigan Yucca therefore as "Yucca sp." or "Yucca in miniature - wild - Michigan" because the plants of this wild population in Muskegon County, Michigan, are rather small. Let's call them just provisionally: Yucca michiganensis ined. nom. nov.

From a distance it appears like a filamentosa but the bloom stalk is pubescent which is a flaccida trait. The pistol is closer related to glauca or arkansana not like any filamentosa or flaccida I've ever seen. Do you have photos of the seeds and seed pods??
this Yucca was blooming in July, and I uploaded this picture already at 23.07.2015 in the forum. Sorry, but for this year the bloom is over. But if next year this Yucca is blooming again, I can take pollen for you, maybe together will new pollen of the monster filamentosa ;-)
Great looking Yucca tree. If possible, could you try to collect some pollen for me of this one? The pollen from the yucca with the monsterflower in your town, did unfortunately give any luck. But maybe this one can? At the moment I have a Yucca "Karlsruhensis type 2 x rostrata in bloom and soon there will be a Yucca constricta in bloom too. Best wishes Benny
Jordi, this year I did not manually pollinate any yuccas. The timing was bad with other events in my summer life, and I was not as diligent as I could have been. I also could not hike western Michigan in search of yucca flowers at the appropriate time. I hope to hike there soon and look for seed pods, though.
Have you hand-pollinated some yuccas at home in the garden? Have you made some more interesting combinations of species and varieties?
Self-seeded. Many of the self-seeded yuccas have twisted leaves in my garden. Perhaps it is a hybrid. The yucca moths fly festively from plant to plant, it seems, in the night.
Jordi, thank you! As you mentioned before, the poppies are sometimes too enthusiastic. I had to remove some of them a few weeks ago. But many remain.
The garden looks quite different now. Seed pods are drying. Cactus flowers are now fruits, ripening in the sun. The Russian Sage is blocking this view now! :)
I have much to share with folks, if you are interested. I suppose they must dry out before I can harvest them. What is your experience with seed pods and harvesting? Typically I would let Mother Nature work on them over the winter, then I would harvest them in the early spring.
Thank you, Thomas, Jordi. I did not harvest any seed, unfortunately, though I really wanted to. I am not certain how fussy the state of Arizona may be regarding seed collection. Not sure. But I do know that they are very strict about collecting plants without a permit.
I have noticed that the seed pods "deflate" when harvested as green pods. Does this destroy the viability of the seeds themselves?
Danke! I imagine the stalks reaching for the sky. This particular plant has shorter, wider and firmer leaves than many Yucca filamentosa. Its stalks are thinner, yet very tall compared with many other filamentosa as well. There is such great variability in these yuccas. One has to wonder if they are selectively bred this way or perhaps hybridized with other species.
Hi, Jordi, I have not dissected any seed pods, though I have made observations while photographing them. They become more constricted as time goes on, it seems. Now finally some seed pods are dried out and split open. Usually I do not harvest them until the next year. But I have quite a few baby seedlings growing everywhere. It's not a problem. But transplanting the seedlings is difficult, due to the tap root. Would you be interested in seeds? I can send seeds from each plant, labeled accordingly, with a photographic reference, after the pods dry out on each. Let me know! I would love to share. Best regards, Miguel
Jordi, the leaf edges (margins) were smooth, although I do not have a macro photo to double-check this, or to show what color the various parts were. This means that I have to return there and hike again! :-P
Hi, Jordi, Walter, thanks for examining the photos. That makes sense. The area itself has highly variable conditions and microclimates, which may promote the variability in the yuccas. I also took photos with another camera. If I have any more yucca photos, I will upload them here, too! Regards, Miguel/Mike
das ist mir auf diesem Bild auch aufgefallen! Vorne rechts eine grünere und breitblättrigere, hinten links eine blauere und schmalblättrigere. Ich halte das aber immer noch für eine natürliche Variationsbreite innerhalb einer Art, möglicherweise bedingt durch unterschiedliche Lichtverhältnisse. Gerade auf Lichtungen in bewaldeten Bereichen sind die Sonne/Schatten-Verhältnisse sehr unterschiedlich.
inded an fantastic shot! This plant photographed here looks real as Yucca madrensis. But that all plants that previously designated as Y. schottii be uncritically simply renamed as Y. madrensis is at least questionable! The real Y. madrensis should have sawn as the simplest Unterscheidungsnmerkmal leaf edges! Do you have by chance observed it?
Thank you, Thomas. I think we may be looking at a couple different species or hybrids here. But.... You guys are definitely the experts here, so I will happily follow your lead.
Hi, Walter! Thank you! I see.... I recognize the JRT seed designation. Whose collection may the RAR be from?
Even my seedlings are looking different. I will take pictures in the next days. I have schottii-seedlings from the following Locations: - Santa Rita Mountains (RAR 20) - Chiricahua Mountains - Santa Cruz County (JRT 8901) - Phoenix, Az.
fantastic pictures ! I have 2 schottii-seedlings from the Santa Rita Mountains. The climatic conditions are nearly the same as in the Chiricahua Mountains.
Hallo Horst , the precise location is 15 Kms South of the city of Nantes , in the Loire Valley , so this about 800 kms far north from the 'côte d'azur'. This is a very temperate location near the Atlantic coast (zone 8b)
faire quelque chose de fondamental: dois-je vous dire combien les temps peuvent poster des images dans un message. Je pense que c'est toujours une honte lorsque les images "vicié" dans la galerie. Je tiens à faire!
Hi Tim , this is Yucca filamentosa used as female plant and pollinated with Yucca rostrata and Yucca gloriosa. I hope the result should be as attractive as your Yucca filamentosa x rostrata from Benny.
thats really a cute and pretty Yucca form! I don't think that this population is an escape of cultivated Yuccas, rather truly it's a native of Michigan!
Thanks for the Macro, Mike. You wrote, tey do not appear to harm the plant. Bit it seems here, however, as if this Yucca bugs also nibble on the ovary!
Mike, Here we quite often find Rapsglanzkäfer, rape beetle Brassicogethes (Meligethes) aeneus on the yucca blossoms, this particularly like yellow flower colors, but also occur in North America! These pollen beetles eat in addition to pollen also stamps and ovaries of the flowers, so are not entirely harmless for Yucca enthusiasts.
Jordi, yes, they are. Thank you for pointing that out. They do not appear to harm the plant, except that they eat the petals of the flowers. I have had the insects just as long as I have had the yuccas, too.
Hello, Thomas. The black insects are little beetles, maybe 5-6 mm in length. They are really dark brown to black with orange. I do not know if they are related to a similar beetle that I have seen on the yucca flowers in Sedona. I thought that it was a curious thing that very similar little insects would be both here in Michigan and there in Arizona on the yucca inflorescence.
Yes Thomas, this one was sown by a friend of me which is a nurseryman, there is 250 units aviable like this one ! Thoses cope with -12°c (!!), unscatered , Under a plastic greenhouse during the winter 2012 , so at a very early stage , that suggest a very promising hardiness !
wachsen die megal... eher langsam oder schnell der verkäufe ebay wollte mir klar machen das 25/30cm 80 euro kosten weil a) sehr langsam wachsen b) ohne schutz gehn c) so selten sind
Hallo Juergen, Yes this is indeed an interesting yucca. I'm sorry Juergen, but I could not produce any pictures of the flowering mother' plant. The story of this particular Yucca is a little bit complicated : 'this was introduced in France few years ago by a french nurserymen, mr Boulay (this why I named this Yucca 'boulay'), but sadly he passed away during the spring 2013... Mr Boulay's son gave me some informations about this Yucca, and told me that his father had taken some cuttings on the mother plant in Spain during one of these past travels. Mr Boulay' son, also a nurserymen, still cultivate and sale this Yucca, that is now enough aviable for the customers. he told me that this Yucca is perfectly hardy for our french climate, and had endured -18°c in the ground without any dammage.
Hi Juergen and Tim, Yes I think you are both right about the parentage,because now the oldest leafs are a little bit colored with anthocyanin stripes like Yucca aloifolia purpurea does, when the nights become more cold (here it's 12°c in the early morning) and the days still warms (24/27°c).
