Type location:
Georgia
Distribution:
This species is probably a hybrid, so it might not have a natural distribution!
Read notes further below.
Short description of the species:
Leaves: recurving, nearly flat, underside rough, 60 to 100 cm
long, up to 5 cm wide, green, grey-green or bluish green with a short brown
spine, the leaf tip has a short brown to black spine.
Inflorescence: it usually bloom in April/May but occasionally
plants may bloom in September/October, this weird behavior could be because
the species is a hybrid of either Yucca aloifolia
X Yucca filamentosa or Yucca
aloifolia X Yucca flaccida the latter
being the most obvious suggestion. The flowers are held above the leaves
and the Inflorescence can reach 150 cm in height.
Fruit: hang from the plant, or occasionally it hang at an angle
below horizontal. The fruits are very hard and dry at maturity. The fruits
rarely split open, and the seeds are difficult to get out from the fruit,
this may also indicate that the species is a hybrid, since it's not "practical"
to have a fruit that the seed can't get out of! And the fruits are a mix
of those of Yucca aloifolia and those of the dehiscent-fruited species,
which also indicate the suspected parentage!
Seeds: Black
Hardiness:
I have now tried three plants of this species in the open garden for
6+ years, and they all look great, they are actually growing a lot faster
than I have expected. Plants grown in pots that are stored in the unheated
greenhouse, are growing a lot slower, specially if they are grown in pots
smaller than 15 liter. The only problem I have noticed is that the
leaves often, due to high humidity, is getting black spots, because of
some kind of fungus infection, which only attack the oldest leaves. The
plant will however quickly outgrow the infected leaves which I cut of in
spring. The cutting of leaves might speed up the speed which the trunk
is growing, so it actually helps the plant to look even greater.
Notes:
Yucca recurvifolia is like a Yucca
gloriosa with floppy leaves, both are hybrid species of either
Yucca
aloifolia X Yucca filamentosa or
Yucca
aloifolia X Yucca flaccida the latter
being the most obvious suggestion for Yucca recurvifolia.
It's quite possible that some of the plants cultivated as Yucca
recurvifolia and Yucca gloriosa in
Europe (and maybe abroad too), could be some of Sprenger's hybrids, and
not the "natural" "species"!?! The last past 8 years I have been collecting
Yucca recurvifolia, and most of them are not very alike, but it's still
too soon for me to be sure of my suspicion!
Yucca recurvifolia is very fertile, and has been used to make many hybrids. Carl Sprenger is the person, whom is known to have has made most hybrids with this species. So far I have not been able to make any hybrids with this species, but I will continue to try this.

Im still working with this species and eventually I will add more accurate details to this page.
#816 Yucca recurvifolia
This plant I got from a friend in 1997. In the summer of 2000 I did
make the first cuttings of it and the "mother" is now planted in a protected
bed (the potted cuttings are stored inside the unheated greenhouse, from
October to May)
I do not have a photo of this one yet.
#1298 Yucca recurvifolia
This one is very new to me, I got it from Al Dribrell in California
as a large cutting with many roots summer 1999. The leaves are more narrow
and is a little more "bluish" than my other plants of this species. I grow
it in a large pot, that are on the terrace during the summer and inside
the unheated greenhouse during the winter, and I will have to grow this
species for a few years before I can make a cutting and try it in the garden.

#1409 Yucca recurvifolia
I got this one from my friend Jørgen in Skovlunde, Denmark,
He has grown it for years, and his largest plant is 100 cm tall and has
a trunk that are 10 cm thick, another of his plants are 130 wide.
#1451 Yucca recurvifolia (maybe yellow flowers!)
I got this one from P.C.O. Nørgaard, Sundby Mors, Denmark, in
the summer of 2000.
His old plant has only flowered once, and this was during the winter,
and at that time the plant was stored inside his basement, with no artificial
light, so the flowers where white, but this could be because of the lack
of sun light. I don't know what to think of this one, it has bloomed twice
for me, and both times during the winter??? In the late fall of 2007 it
has again started to make yet another flower bud.
#1450 Yucca recurvifolia marginata (yellow edge, variegated)
I got this one from P.C.O. Nørgaard, Sundby Mors, Denmark, in
the summer of 2000. It's still a very small plant, so I can't write much
about it yet.
#1439 Yucca recurvifolia.
This one is probably a form or a hybrid of Yucca recurvifolia
very much alike Yucca ' Danica '. I got this one is from my
friend Bjarne Kjempf, Løvel, Denmark, in the summer of 2000. He
got it from an old man who had a 100 cm tall plant with a trunk 10 thick.
The leaves are bluish-green. In pots it is a slow grower, but when planted
into the ground in the garden it grow quite fast.
#1455 Yucca ' Danica '
This one is probably a form or a hybrid of Yucca recurvifolia.
I
got this one from P.C.O. Nørgaard, Sundby Mors, Denmark, in the
summer of 2000. He did get it from from the isle Samsø, Denmark,
the story behind the plants is something like this; a sailor had it with
him home from a one of his trips, but no one know from where he did get
it. My plant is very small, and I hope to be able to propagate it, so it
can be more known.
#1452 Yucca X Victor Emmanuel II (Vittorio Emanuele II)
Hybrid by Carl Sprenger, Yucca aloifolia
purpurea x Yucca recurvifolia
I got this one from P.C.O. Nørgaard, Sundby Mors, Denmark, in
the summer of 2000. It's still a very small plant, so I can't write much
about it yet. It's hardy if grown in an unheated greenhouse, but in the
garden it will die!
