Notes:
It should be noticed that Sprenger's article were published in 1920,
3 years after his death in 1917.
In the article mentioned above Sprenger that he also made hybrids with
Yucca
schottii, but it seems as he did sell all the plants as seedlings,
and did not grow any to bloom, so no specimens were given a name. Those
hybrids with this seed parent were most likely made and sown sometime between
1870-1890.
He mention a Yucca schottii x flaccida
on page 113. So he did at least made hybrids with this "parenthood".
When Sprenger did write the above shortly before his death in 1917 he did
know of a plant in Napoli, Italy, which he believed to be this hybrid.
Unfortunately were many of Sprenger's plants destroyed by volcanic ash
when Vesuvius erupted in 1906.
Only few is known to be in cultivation:
Yucca 'Vittorio Emanuele II'
Yucca 'Floribunda'
Yucca 'Elegantissima'
It is possible that there more "out there", but the above three is the
only forms which I know of. Sprenger did also sell many unnamed hybrid-seedlings,
and is very possible that some of those is growing in different places
around the Mediterranean or on Corfu on which he lived from 1907 until
his death 1917.
If any of the readers know of any beautiful Yucca plant in this area
of Italy, I am most interested in seeing photos and receive a small cutting
of it.
