Can seeds from hips that have been dried out for 4-5 years still germinate?
I think it would depend on storage conditions and what type of rose they are from. It can’t hurt to try. I wouldn’t think they they have much chance.
I’ve heard of seed from certain Northern species held frozen and still viable for a number of years.
Thank you Robert. I’ll try the floating test to see if any sink and go from there.
I had some 3 years old ‘Bonica’ seeds as germinated last year. The seeds have been inside the hip indors in my house. Try if this is some interesting seeds Rob.
Hearing about your success with dried ‘Bonica’ hips/seeds gives me encouragement. I’ll give it a try Roger. I do have some interesting crosses dating from 2001 where the hips have been stored in a dry environment. For your ‘Bonica’ dried hips, did you soak them first before opening them or just crush/open the dried hips?
I routinely dry many seeds such as rugosa, banksiae, multiflora and wichuraiana derivatives among others.
Botanical Gardens do usualy preserve dry species rose seeds or fruits. I had diverse results from failure with the very large seeds of chinensis spontanea to success with roxburghii. So so with setigera.
Banksiae old dried seeds did germinate much better for me than fresh ones…
This thread gave me some encouragement to go back and collect some dried OP his from a cultivar I’ve been curious about. I’ll let you know if I get success.
The only time I’ve had success (or tried much for that matter) was with some dried OP hips of Dr. A.J. Verhage. I did get germination. The seedling was very unimpressive.
Rob, i just open the dried hips, then soak the seeds in water for about 22 hours.
Thank you all for your input. I’ll proceed forward using dried the seeds and use roI’m really glad I didn’t toss them out afterall. Appreciate the tip on how you soaked the seeds Roger.
After being absent from this site for about 4 years it’s great to come back and see familiar names and find that everyone is still so very helpful. Thanks again.
Rob, I lost some hips for a year a few years back in the bottom of the old refrigerator that we keep in the garage for my rose breeding and for overflow from the house. When I found them the following year during harvest time, I noted that the hips had dried hard. I also noticed that they were some of my earlier important hulthemia crosses. So not wanting to throw them away, I planted them per my usual routine. Germination was excellent.
I was so close to tossing these hips and am so glad I posted this question first. It’s great you were able to get germination from seeds of your hulthemia crosses Jim. I hope you get something really interesting from them.

I’ve had the first germination from seeds that were stored since 2001-2003. The first to germinate are from openly pollinated L83 seeds after 4 months in the fridge. I was beginning to wonder if any of those old seeds would germinate. Hopefully more will as well.
What is “L83”?
Robert, concerning what is “L83”, see:
Good heavens! That is a lot. I do know, that for some species roses the seeds naturally germinate over a period of several years. Some people think they may have evolved that way so that if any one year has bad conditions there will still be some seeds germinating next year and the next. Although most modern roses don’t tend in that direction, I would imagine that in most roses, to varying degrees, there would be some built in tendency for lasting viability in a dry seed.
