Yucca hybrids,
made by
Benny M. Jensen
in the summer of 2008.



Also in the summer of 2008, did I make new cross pollination's of several Yuccas. You can also read about the first year of pollination in 2003. and about the hybrids of 2004

In 2008 I did make cross pollination of about 550 flowers, both with pollen from my own plants and with pollen from friends from around the world. I wish to send my special thanks to: Tim Behan (U.S.A.) , Thomas Beouf (D), Sascha Swatek (D), Sascha Weissbeck (D), Ruud Wouterson (NL), Steen Stjerne (DK) and Mark van Zwet (NL), whom all did send me pollen for the experiments, I am very happy for their support and help in this project. I were also so fortunate that I were allowed to pollinate and collect pollen from a special trunk forming Yucca which were growing in a garden in a village close by our home, Many thanks to Inger and Bendt. This Yucca is not 100 % identified yet, but it could be the plant known as Yucca gloriosa [var. robusta]. It had very good pollen and were VERY receptacle for pollen from most species/forms which I used on it, further on in this page it will be listed as Yucca sp. "Hæstrupvej".

The weather conditions for pollination of Yuccas were not perfect in the blooming season, the first flower to open were Yucca angustissima ssp. kanabensis (June 28), but I did not have any other pollen to pollinate it with until the 7th. flower opened and I had received pollen from Thomas Beouf (D) and Steen Stjerne (DK). The weather changed in early July and there were many rainy days, then there were a rather long period with temperatures above 25 C, and it seems as the best time for pollination is in the late afternoon and early evening on a dry day with temperature above 15 C in the night and below 25 C in the days. I still have a lot of notes to evaluate, until I can give a more detailed description of the best weather conditions for pollination of Yuccas. Due to the cold wet weather quite a few fruits did die while they did get fungus or they did not grow to maturity before the fist frost. Flowers pollinated after July 26-27 did fail to finish.

Of the about 550 pollination's in my own garden, and on the plant the private garden in the village close by, did I get 77 fruits with good seeds and a total of 40 new Yucca hybrids, most of them involving a trunk forming Yucca species/form.



Below you can see which pollination's I were able to collect seeds of in 2008:

I really look forward to sow the seeds in the spring of 2009, and to follow the seedlings grow to mature plants. Of course do I have specially hopes for those hybrids, which eventually may a trunk, as there are so few trunk forming Yuccas, which can be cultivated up here in northern Denmark (lat. 57.5).


Plants from the above pollination's will not be available until in the summer of 2015 at the earliest! There will not be offered seeds of the above hybrids!
