Yucca hybrids,
made in the summer of 2003.



In the summer of 2003 a friend of mine Pia Larsen and I tried to cross pollinate several Yucca species/forms/hybrids with each other. We have been trying to follow the footsteps of great nurserymen such as Carl Sprenger, Willy Müller and Graebner. I have tried pollinating Yucca's before but without getting any fruits with seeds, but then I seem to have learned how to do it. We did cross pollinate the following species and forms:

(The number of fruits were counted on August 10th. 2003)
#454C Yucca arkansana (stiff narrow leaded form) X #1465A Yucca filamentosa, 3 flowers pollinated, =  1 fruit (2 aborted)
#818 Yucca 'Bright Edge' X #1461 Yucca glauca, 10 flowers pollinated, = 9 fruits (1 aborted)
#818 Yucca 'Bright Edge' X #1465B Yucca filamentosa, 1 flower pollinated = 1 fruit (0 aborted)
#1465A Yucca filamentosa X #454C Yucca arkansana (stiff narrow leaded form), 5 flowers pollinated, = 1 fruit (4 aborted)
#1465A Yucca filamentosa X #49 Yucca flaccida, 2 flowers pollinated = 2 aborted!
#1465A Yucca filamentosa X #1461 Yucca glauca, 6 flowers pollinated = 5 fruits (1 aborted).
#1465B Yucca filamentosa X #1461 Yucca glauca, 2 flowers pollinated = 2 fruits.
#1402 Yucca filamentosa (beautiful tall form from Dr. Lorek in Germany) X  #1461 Yucca glauca, 8 flowers pollinated = 6 fruits! (2 aborted).
#1402 Yucca filamentosa (beautiful tall form from Dr. Lorek in Germany) X #332 Yucca filamentosa, 5 flowers pollinated = 2 fruit, (3 aborted).
#1578 Yucca filamentosa X #49 Yucca flaccida, 1 flower pollinated = 0 fruits, (1 aborted.)
#332 Yucca filamentosa X #1461 Yucca glauca, 12 flowers pollinated = 6 fruits. (6 aborted)
#49 Yucca flaccida X #1465A Yucca filamentosa, 1 flower pollinated = 0 fruits, (1 aborted)
#49 Yucca flaccida X #1578 Yucca filamentosa, 1 flower pollinated = 0 fruits, (1 aborted)
#49 Yucca flaccida X #1582 Yucca 'Ivory', 1 flower pollinated = 1 fruit. (0 aborted)
#49 Yucca flaccida X #1402 Yucca filamentosa (beautiful tall form from Dr. Lorek in Germany), 2 flowers pollinated = 1 fruit, (1 aborted).
#49 Yucca flaccida X #332 Yucca filamentosa, 2 flowers pollinated = 0 fruits 2 aborted
#49 Yucca flaccida X #1461 Yucca glauca, 14 flowers pollinated = 11 fruits (3 aborted) This hybrid will probably be quite like a hybrid made by Graebner in 1899, which is know as Yucca 'Karlsruhensis' and was described in 1903.
#1461 Yucca glauca X #818 Yucca 'Bright Edge', 3 flowers pollinated = 0 fruit (3 aborted, one of these were 11 days before it aborted!?)
#1461 Yucca glauca X #1465A Yucca filamentosa,  4 flowers pollinated = 0 fruits. (4 aborted, two of these were 11 days before they aborted!?)
#1461 Yucca glauca X #1402 Yucca filamentosa (beautiful tall form from Dr. Lorek in Germany), 4 flowers pollinated = 2 fruits, (2 aborted)
#1461 Yucca glauca X #332 Yucca filamentosa 3 flowers pollinated = 1 fruit?  (2 aborted)
#1461 Yucca glauca X #49 Yucca flaccida, 6 flowers pollinated = 1 fruits (5 aborted, four of these were 11 to 12 days before they aborted!?)
#1461 Yucca glauca X #1582 Yucca 'Ivory', 2 flowers pollinated = 0 fruit (2 aborted)
#1461 Yucca glauca X #500 Yucca sp. Hybrid?, 3 flowers pollinated = 0 fruit  (3 aborted)
#1582 Yucca 'Ivory' X #1461 Yucca glauca, 6 flowers pollinated = 2 fruits (4 aborted)
#500 Yucca sp. Hybrid? X #1461 Yucca glauca, 13 flowers pollinated = 9 fruits (4 aborted)
#500 Yucca sp. Hybrid? X #332 Yucca filamentosa, 3 flowers pollinated = 2 fruits  (1 aborted)

As you can see is the Yucca glauca pollen very good and it is compatible with all the plants that it was tried on. The pollen from #332 Yucca filamentosa was not easy to collect, and also not very good pollen, as many pollinated with that one aborted! It looks like that the flowers of Yucca glauca, may have needed more pollinium, as many of the fruits aborted when they were 10-12 days old, and it looked like they didn't have had pollen enough to pollinate the lower part of the fruit, so it shrunk and led to abortion.

Not all of the above fruits had viable seeds, some of the fruits did not mature probably before the first frost in September, and others were damaged by fungus due to wet weather. One of the plants (#332 Yucca filamentosa) is obviously sterile as non of the fruits were having any viable seeds at all, the pollen from is were OK on some of the plants which it was tried on and it will be the "father" 3 different crosses and 5 seed pods.



Here are the list of viable pollination's of the summer of 2003:

I have harvested totally 54 fruits with viable seeds in the fall of 2003. Most of the fruits were ripe when they were 10-12 weeks old, but others were not ripe until after 16 weeks after pollination!


Fruits on Yucca glauca (BMJ #1461) Note that one of the fruits are deform, as if it didn't receive enough pollinium!!

A few plants from the above pollinations were released for sale in June 2006, and more were released in 2008. There will not be offered seeds of the above hybrids!
