Hello there fellow yucca enthusiasts, I'm writing from Canada (zone 5a but equivalent to U.S zone 4) it's been 2 years that I caught "yucca fever" and I've been trying to germinate many yucca varieties with my ultimate goal of having the best cold hardy trunking yucca for my climate. here are some of my new seedlings the youngest ones 4 months old, a big thank you to Tim for my new babies. yucca Flaccida (Poconos Mts, PA)x Filata X Filamentosa x Rostrata #1 yucca Flaccida (Poconos Mts, PA)x Filata X Filamentosa x Rostrata #2 yucca Filamentosa X Rostrata yucca Gloriosa Tenn. X Filamentosa x Rostrata #1 & 2 (I have only 2 of these so I'm keeping them in pots until next year, I'm not taking chances with my rough winters) yucca Constricta x filamentosa X Filata "Big Mama" yucca Filata "Big Mama" (this one was strugling in it's growth stalling at 4 leaves but I repotted recently and added a root booster and it grew 2 new leaves!) here are some other hybrids 6-7 months old yucca Glauca X (Filamentosa x Glauca) yucca Elata X Filamentosa #1 yucca Elata X Filamentosa #2 yucca Elata X Filamentosa #5 yucca Elata X Filamentosa #6 yucca (Filamentosa x Glauca) X Elata yucca Thompsoniana X Campestris (this will be dug out at the end of summer, may not be survive -30C+ as a first winter, I lost all my Rostrata seedlings this past winter when it hit -36C with winds) Thanks for your time

Great looking hybrids Edwin! It will be interesting to see which ones will be hardy enough in your zone 4. Please post photos at the end of the growing season.

Thank you Tim. I'm hoping at least one of your hybrids could be hardy to my zone, yucca Flaccida x Filata X Filamentosa x Rostrata could be it having lots of filamentosa/flaccida genes for hardinesss and the elata/rostrata genes to make it trunk.......also my filamentosa x glauca X elata could be very hardy. time will tell, I will post pics of their progress...

I've crossed Y. fila x rostrata X glauca v stricta this season. I hope the pods ripen. If so, these should be very hardy! Hopefully some of the hybrid seed will be rostrata-like in foliage.
