Where did I get the plant from:
Sown from seeds bought at Mesa Garden MG 1984.5, seeds sown in 1992. Seeds collected in Franklin Co., North Carolina.

Short description of the plant:
Plant: acaulescent with several large rosettes, forming short rhizomes. Leaves: dark gray green, rather stiff, 40 cm long 3,5 cm wide around the middle, roughened surface and back in lines, slightly glaucous, with many thick curly fibers at the margin of the leaves, see photo below:

Leaf of Yucca filamentosa, from Franklin Co., North Carolina, note all the thick curly fibers.

Inflorescence: pubescent, 115 cm high, paniculate with few short branches up to 12 cm long, held in an upright angle. Scape: 50 cm starting high above the leaves. Flowers: floppy bell shaped, white, tinged with green, rather large 8 cm across. Fruit  The fruit apple-green, has a smooth surface, 23-27 mm thick and 38-58 mm long, and has a rounded (convex) back.
Seeds not know at the time of writing!

Where do I grow the plant:
I grow it in a raised well drained beds, but I might try it in "normal" garden soil, when I start to propagate it.

Hardiness:
It's is not as hardy as Yucca flaccida, but i a well drained sunny spot it will do just fine.

Other notes:

Flowered first time August 1998, second time July 2003.

I have always thought that this plant was Yucca filamentosa var. concava as it has lots of thick curly fibers, stiff leaves etc., but after that I have been able to pollinate it, and see the fruits I'm more convinced that it's a short leafed form of Yucca filamentosa.

In the summer of 2003 I tried to pollinate the flowers with pollen from a Yucca glauca:

#332 Yucca filamentosa X #1461 Yucca glauca, 12 flowers pollinated = 6 fruits. (6 aborted)
The seedlings from this cross, has narrow leaves as 7 months old seedlings!

I also used the pollen from this plant to pollinate the following:

#1402 Yucca filamentosa (beautiful tall form from Dr. Lorek in Germany) X #332 Yucca filamentosa, 5 flowers pollinated = 2 fruit, (3 aborted). The seedlings from this cross, does already show quite wide leaves as 7 months old seedlings!

#1461 Yucca glauca X #332 Yucca filamentosa 3 flowers pollinated = 1 fruit?  (2 aborted)
The seedlings from this cross, has narrow leaves as 7 months old seedlings!

#500 Yucca sp. Hybrid? X #332 Yucca filamentosa, 3 flowers pollinated = 2 fruits  (1 aborted)
The seedlings from this cross, does already show quite wide leaves as 7 months old seedlings!

This is the new rosettes that are grown from the rhizomes after the original rosette died after flowering.
