I have not.  I am curious how that would go.  Are the tines spaced correctly?  Do the forces crush them?  Those are my first worries.  I don't have black raspberries here, but I do have red and the way the berries are clustered and don't ripen evenly has kept me from trying this on them.  Do black raspberries ripen more uniformly in the cluster?

Aaron at Edgewood is the source of the Salish Blue for EFN.  Edgewood Nursery  He's sold out this year, but I'm sure he'll have more next year, so you may want to get on his mailing list.

The original source where I found them to share with Aaron no longer seems to sell them, so it may have been quite fortunate to get those into his caring hands.  I originally found out about Salish Blue right here on Permies!  Thank you Nicole, small world, right?

Greg Martin wrote:Although hopiness plants set lots of lovely flowers, I've read that their flowers require more force for a bee to open and that this can reduce the number of pods that form.  I wonder if we could select for flowers that are easier to get into.

I wonder if there is a particular strong armed bee that can get in to polinate them which is not widely populous? I've noticed some of our local bees, cheat and bite though the base of some flowers, which might also prevent them pollinating.

Also there's the issue with many northern strains being triploids and not setting seeds.  So another issue is selecting for diploids that ripen seeds in a short season.

Can you tell the difference between them visually, or will the proof be in the seeds setting? With triploid apples they can be pollinated by a normal apple tree, so can a triploid Apois be pollinated by a diploid one resulting in fertile seeds? my genetics is so rusty....this article on dandelions implies that it will be pretty rare, but I don't know whether Hopniss are likely to be the same.

Nancy, I've heard rumors of hopiness plants that self-pollinate.  If I manage to find such a creature I will get back to you about that.  The triploid apple is an interesting case.  My assumption is that they are able to set fruit when pollinated, but that any seeds would be sterile, if they set seeds.  I'm not aware of a way to tell if a hopiness is triploid by looks, but hopefully someone else knows.  I'll try and pay closer attention to my triploids to see what can be seen.  Extra chromosomes often leads to larger plant parts, so there may be a way to measure parts of the plants to find out, but not sure at all!

Bless you good Greg!!!  Very much appreciate that.

I should probably add that mine are in a somewhat sheltered spot, so no strong winds.  And if they end up leafing out then the leaves will die if the temps go back below freezing.  But when they are dormant they can take dips into the 20s.  Some varieties have been known to go lower during dormancy and wake up fine.

Right now I'm waking up one of my potted figs in my sunroom and it's starting to push out this year's figs already!  That one will have to stay inside until we're done going below freezing.

I try not to uncover mine until I know it won't get colder than the 20s.

Slow going in trying to find dwarf forms, but here is another arboretum, this one in Newark, OH, that says they have one.  Their site lists it as 'Nana' and has an accession number, so progress, maybe?
I'm curious if this is the same tree as the one in MN.

Any idea if they have more than one dwarf form?  So far they haven't gotten back to me about their dwarf.  I bet they wouldn't mind someone gathering a few pods.  If I ever get a chance to get out there and if this one is male I'd be asking about if it was ok to snip a few scions for grafting to do breeding work with.  Seeds would be ideal, though.  I'd also love to buy a dwarf form if I could find one.  With them being a landscape arboretum I'm really hopeful that they can direct me to a nursery.  My fingers are still crossed.

Yeah, those plants that have both male and female flowers (monoecious) would be wonderful for a plant breeding project.  If anyone can send seeds from a monoecious tree, I will do some breeding and selection work!  Online I also found a picture of a dwarf form at an arboretum in Minnesota.  I contacted them to try and find out more about that tree's origins and if there's any way to get one.  It might be wonderful to have dwarf monoecious plants for harvesting the immature seeds from as a perennial giant pea tree, no?!

Here's the picture of that dwarf tree.  I don't see pods and apparently that picture was taken in September, so probably a male?  I'll update if I learn more about it.

What did the chemist say to her valentine?
I think of you periodically.

What did the painter say to his valentine?
I love you with all of my art.

What did the chef give to his valentine?
A hug and a quiche.

And all I got for y'all are some corny valentine jokes!  Happy Valentine's Day!
