Is there any rhyme or reason to which species have specific soil pH needs (either acidic or basic)?

Yes

 

[koshki]

I'll bite.

What determines whether a cyp has an acidic or basic soil requirement?

their natural habitat

 

[koshki]

Well, then, that explains things!

Most Cyps require a continuously moist, yet air rich compost. Dr. Bill Steele put in nicely in the cultivation section of his site - when you re considering what to plant in, think fluffy. The pH is not as important as those requirements for most species. The exceptions would include the true acidofile C. acaule or C. candidum which prefers just the opposite - alkaline soils. The bulk of the other species and their hybrids are quite content with slightly acidic to sweet compost (~6 to 7). Inorganic based compost seems to yield better results over time than highly organic ones, too.

Some kinds in my experience will die in inorganic soil and kill easy.
Palangshangense I killed in inorganic soil, they are sitting in pure humus and doing well now over 3 years and growing.
The same with debile a lot of shade and no inorganic components an they are growing like hell, and showing up even after such hard winters with - 22 C and no cover at all. So I am not sure all like inorganic soil.

Cypripedium formosanum

Cypripedium acaule

Cypripedium tibeticum forma 'red leaf'

cheers

 

[Ernie]

Awesome formosanum!!!

How does the flower color of tibeticum vary between the red leaf and normal leaf versions? Darker flowers on red leaf?

Love your new signature.

 

[Erythrone]

Splendide C. tibeticum!!!!!!!!!

Nice plants Dieter. How long have you grown that formosanum?

 

[yijiawang]

excellent! very beautiful plants and grow very well

......... How long have you grown that formosanum?

Tom, I bought the formosanum about 20 ? years ago ( I am not sure )
from Mr. G.Wetzel, you will know him.

It always grew in a large 50 cm pot, but in the meantime it was several times divided and replanted. Pots are sunken in shady garden place and have only a plastic cover in winter.

Maximum was about 50 growths in a pot, but when too crowded, I repot and give away/sell the divisions.

at present I have two more pots of about same size................

 

[KyushuCalanthe]

Yes, C. formosanum can grow a lot in 20 years! Great plant.
