Vertical Palm Success – Caryota mitis Overwinters at 443m Elevation (Arbon/Stachen, Switzerland)

[Mazat]

Dear Grandmasters and Palm Enthusiasts,

I am erupting with pure botanical joy! Today, March 15th, 2026, I can confirm an absolute vertical wonder on my Balkon-Fortress in Arbon/Stachen (Lake Constance, Switzerland). My Caryota mitis, situated on the 4th floor at 443 meters above sea level, is showing an incredible vitality eruption.

The Exposure: Despite being in the shade at 443m, my Intertronic station recorded a local heat pocket of 16.5°C, while the surrounding region is significantly cooler at 6.0 -9°C .

The Resilience: The trunk is rock-solid and cannot be pulled out (zero spear rot). New green shoots are emerging directly from the center.

The Micro-Climate: This 4th-floor micro-climate proves that elevation and vertical positioning can create unique survival pockets for species often considered too tender for Zone 8a.

The Caryota mitis on the 4th floor lives! The Arbon/Stachen-Sog of vertical life is unstoppable!

Beautiful. Come on Mazat, these palm trees will only enhance their beauty. Congratulations. I hope to protect mine now from the Southern Hemisphere winter.

My Archontophoenix cunnigamiana suffered last winter and their leaves dried up like husks. Afterwards, new leaf buds emerged and they recovered.

That's really amazing and shows that she's more resilient and adaptable than we might think based on logic. We are so happy for you, Hugo 🤗

Great news ! Caryota Mitis are my favorite of all the common fishtail palms . When one trunk flowers , simply remove that stem and more continue growing . I have a few clumps around the house . I cut the flowering stems (trunks) out about once a year. Some of them get pretty tall. Harry

‘This one had a couple large stems removed last year .

Thank you very much, Harry. Wow, amazing, Harry. What a beauty 🤗

The ultimate Hattrick! 3 out of 3 Caryota mitis are erupting!

The second and the third are now pushing pushing strong, healthy new spears simultaneously.

We are very very happy about that🤗

Thanks, friend. Palm trees recover more in spring and summer. And each variety of palm tree is a unique and separate kingdom.
