Where did I get the plant from:
I did notice this plant a few years back, growing in a garden near
by. I first thought it was a Yucca recurvifolia,
but when I got a closer look in the summer of 2008, when it was about to
bloom, I could see that it was NOT what I first thought.
Short description:
Plant caulescent with a short trunk, one or several very large
rosettes, forming new rosettes from short rhizomes, and inside the old
bloomed rosette . Leaves: glaucous, bluish green, up to 100 cm long,
up to as wide as 7 cm around the middle. The underside of the leaves rather
roughened in the 1/3 of the leaf. The spine in the end of the leaves VERY
sharp. Inflorescence: glabrous paniculate, many thick (4-5 mm) short
branches up to 15 to 25 cm long, held in an upright angle at about 30 degrees,
15 to 20 flowers on each branch. Scape: 70 to 85 cm starting in
between the leaves, in 30-40 cm hight from the rosette. Flowers:
campanulate (bell shaped) usually arranged in pairs.
Fruit apple-green,
has a smooth surface, 18-21 mm thick and 55-75 mm long, pointing upwards
or rarely sideways. Seeds: black, 4-5 mm wide, 1-3 mm thick, No
wings..
Where do I grow the plant:
In the garden on Hæstrupvej, it is growing either in a large
pot, or planted into the garden in normal garden soil, which in this place
is rather heavy in clay.
Hardiness:
I believe it to be very hardy, in the garden on Hæstrupvej it
has been grown for 7 years, and in a garden in the city of Hjørring,
it has been grown for more than 10 years.
Notes:
This plant were brought to Denmark, by a tourist bus driver, many years
ago, and it could be one of Carl Sprenger's
many hybrids?
Other notes:

I also use the pollen to pollinated it with:

sp. [gloriosa forma robusta]. Made by Benny M. Jensen, Denmark,

It will be very interesting to see the outcome of the new hybrids, and hopefully some of them will grow trunks too, but I do not expect flowers in the new hybrid until 2015 at the earliest!
