Well... The first word that crossed my mind was: Wow. Then the second one: Wow, with more intonation on the first letter.
That's some really good work you've been doing over these years. I see a lot of wonderful (and my dream) plants.
I have so many questions that I will probably forget to ask many of them, but a "short list" of some questions is here:
PALMS:
1) This occured to me the moment I saw your palms. Do you protect them during the winter? Is the protection necessary? Some of the plants you have are really borderline and cause you have a climate almost identical to mine, this would be the most important question that comes to my mind.
2) Trachys don't really need protection in your winters, do they?
3) I always believed, that Chamaerops humilis 'cerifera' was somewhat more frost and cold resistant than other green forms of Chamaerops, is that so?
4a) Your Jubaea seems to recover from some frost damage on its fronds. I really do hope to cultivate a more resistant Jubaea straint idle for my region, started germinating Jubaea seeds last winter (which is about 70 years of active production, caring, adapting and growing from seeds til it fruits for me... sigh).
Your plant seems to be about 8 to 13 years old, right? Do you overwinter it with protection, or simply mulch it and that's it?
At what temperature did you see the first frost damage to the leaves? Are the other, undamaged leaves new foliage, or just the old one, but undamaged?
4b)

Butia capitata x Parajubaea cocoides? That will be a tough one. But it has potential to be the most beautiful palm in your wide neighbourhood. Good luck on that one. I can't wait to see your progress with it.

5) What was the problem with Sabal and its defoliation? I remember it was a new addition to the collection when we spoke together in winter, was it because it wasn't established well enough yet? Do you think that it grows well in wet winters? Sabals need (or at least I read so) dry winter. Does it grow well for you?
6) In general, do you plant your palms directly into Swiss soil, or do u add sand and small rocks to the mix?
BANANAS:
7) Your Orinoco really looks as if it took some beating recently, I hope it roots well for you. Have you tested its cold-hardiness in your climate yet? Do you plan to?
8) Your Dwarf Brazilian is indeed as beautiful as I imagined it. If I'm not mistaken, that's my pup's mom, isn't it?
9) I don't see your Raja Puri pup? I hope it survived, didn't it?
10) Have you tried overwintering bananas outside in the soil or not? Do they perform well during colder days or not?
11) About your iron cage, does the soil hold on the roots when you pull it out? Or not?
FIGS:
I can't promis anything just yet, but there are some very strange varieties of figs in my neighbourhood, they were brought here from Dalmatia, about 500 years ago, during the great migration of Austro-Hungarian monarchy's nations. They are perfectly adapted to our climate now and don't resemble Brown Turkey that much, so I think it's another, local variety. It has very strange and interesting leaves. I will try to get some cuttings and propagate them, if you are interested, I can offer some.
You gave me Lagenaria leucantha longissima 'Herkuleskue' and it's growing well. So far. It's about 1,6m tall and grows more vertically. It started to grow and climb my tomatoes that are about 2,1m high now. Really a fighter, but I don't know about the blossoms. No bee seems to be willing to pollinate.
Other plants and seedlings: Amazing, really.
I especially like what you did with your vines. I might try to do some construction for some vines later this year.
Your egg producers are nice. Much nicer than my neighbour's, whose are literally monsters. Very large, old, robust and strong... Blah.
So many thoughts in my head now... thanks for the pix.
