Any one with some advice on the methods to germinate these seeds.I also read these are hardy down to -15c,now would this be for breif periods or can they stay this cold for extended times with protection,thanks for the help

I've never tried them before but should be very easy to sprout. Try one seed under 1/4 inch of soil and keep moist untill it sprouts. Should take 3-10 days. Very easy. :D

They can probably take cold for brief periods. -15c won't hurt most yuccas if brief. :wink:

Here's to all the global warming pushers, may your winters be -30 below and four feet of snow in your driveway. Because I want you happy.

I typically germ Y. filifera and other Yucca seeds by placing the seed on top of the soil medium and covering the seeds with 1/8" deep layer of sand. Bottom water. Seeds typically germ quickly and leaves will emerge in 2 to 3 weeks but east coast Yuccas seem to be 1 to 2 weeks slower for some reason. Room temperature is fine (70F). Warmer is OK too but too much cooler and germ % will decrease.

Here's a Y. filifera seedling grown from seed (2002 photo).

I also grew some taller specimen plants back in 2002/2003. When kept bone dry under a poly roof, covered with a blanket and heated it withstood a low temperature of 6F (as measured under the blanket). Another specimen which had no protection from cold rain/snow died in December and the low was only 13F or so........far less hardy in cold/wet conditions. Keep yours bone dry if your drop below 20F.

the yucca filifera in that photo is about 2 years old. Yuccas will grow very fast if kept in full sun and their root tips are not restricted (they don't like to be pot bound). One must transplant them every 2 months in the growing season for fast growth.

I've never had a problem with yucca seeds freezing. :|

3 days...wow, gotta be a record! Congratulations.
Does any one know if freezing temps will affect the seeds in the mail.
I've asked this Q a few times myself, and apparently "cool hardy" palms/yuccas aren't affected.
In habitat, seeds are exposed to low temps, lying on ground.

But freezing in the mail isn't good for palms that NEVER see frost, i.e. Cyrtostachys (received in early December -6C 21F ) :?

Also emailed a Q to RPS re "irradiation at borders" (security process?).
Toby kindly emailed back "no problem".
hmmm...radioactive seeds :lol:
