#1758 Yucca recurvifolia.
This form of Yucca recurvifolia is very much like Yucca ' Danica ', and it may be the same form?. I got it from P. C. O. Nørgaard in 2003.

Short description of the species:
Leaves: recurving, plicate, underside rough, 60 to 100 cm long, up to 6 cm wide, bluish green with a short brown spine at the tip.
Inflorescence: it usually bloom in April/May but occasionally plants may bloom in September/October, this weird behavior could be because Yucca recurvifolia might be 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: not known
Seeds:  not known

Hardiness:
This form is until now, one of the best forms of Yucca recurvifolia, I have tested in my garden here in northern Denmark. It is actually growing a lot faster than I have expected, but 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.
