warmer growing cypripediums

[youngslipper]

please give me some names of cypripediums that can tolerate warmer temps like 6 C in winter and up to 28 C in summer

 

[Linus_Cello]

species or hybrids?

species:
Cypripedium kentuckiense (needs very well draining media; sand)
Cypripedium pubescens

hybrids: Gisela, Sabine (alba), Lucy Pinkepank

Good point. Done.

Oops messed up again. Any will do

Best warm growing species in my experience is C. formosanum - easy. Others that are warm tolerant are much more difficult - kentuckiense, acaule, and henryi for example.

So Tom would you say that formosanum will get by with 5 or 6C min over winter and still grow and flower well?

Definitely. It never averages below 5 C here and that only lasts around 2 and half months. This species requires the least amount of cold vernalization of any of the temperate Cypripedium species. C. kentuckiense or southern populations of C. acaule come close to that, but are much harder to grow long term.

Just keep the formosanum well mulched during the winter.
acaule are tricky for the need for acidic conditions.
kentuckiense are found in Texas in the US, where it get's to 38 C easily. According to some who grow it well, the trick is well drained soil.
For easier growing, kentuckienese hybrids that look very similar to kentuckienes are another option, like Lothar pinkepank (or LP x kentuck).

Thank you all
