Cypripedium calceolus

[Simon Richartz]

calceolus; watching the snow; waiting for spring.

Welcome first of all.
Secondly... would you like to share your growing methods? Are those just in a sterile jar?

 

[abax]

Welcome to ST from KY. Are you planning to plant all these outside?

 

[NYEric]

Welcome from NYC. Good luck with those, please keep us posted.

I want two! Can't wait for spring.

I'm anxious to see what comes out of the ground of what I planted last fall.

 

[PaphMadMan]

That is an impressive crop of very healthy seedlings ready to come out of flask. Please update when you get to next steps.

 

[Simon Richartz]

Thanks for your welcome.
These young plants are for my garden. I will store the jars in a fridge from next week till May. That’s the reason I sorted them the last days and an occasion for the pictures.
European calceolus grows in my garden in the natural soil without any shelter.
Ulla Silkens five years in the garden.

In 2015 I made this picture from the sorting of calceolus jars before cold treatment in January.

My favorite hardy orchid are Dactylorhiza; so I mostly grow these in my garden.

Very impressive

Looks like a bank vault!

I can't believe it. What an excellent thing. Do you have to amend your garden for the marsh orchids? It looks like you have enough for all of Lower Saxony.

For growing marsh orchids (and Cypripedium) in sandy soil it is helpful to add some dolomite CaMg(CO3)2. Before the place became my garden; it was used intensively for hay production with the result of acidification. In the early years I added lots of calcium to the soil for a suitable pH. Marsh orchids and their mycorrhiza are not in need of Ca; but because of any reason it makes the plant healthier. (for Cypripedium mycorrhiza Ca is indispensable)

The structure of this soil is difficult to describe, it is suitable for most European orchids.

Growing marsh orchids in vitro is easy

Very impressive programn:clap::clap:

I think you should correspond with Dr Zettler at Illinois College.

I don´t think that this is “science”. It doesn’t even get in touch with the “scientific way of processing” nowadays. Growing Cypripedium kentuckiense in a jar till it could flower is more like growing a bonsai than anything else.

Don't worry about that. Dr Z operates a orchid micro-propagation lab dedicated to orchid conservation. He specializes in mycorrhizal relationships and collaboration with other successful flaskers would always be viewed as potential to learn new insights.

Love those purple leaves.

 

[Simon Richartz]

I like the purple leaves too.
Unfortunately most lose some color during summer.

What is the dactyl potting mix, and how do you over winter?

 

[Simon Richartz]

The “potting mix” is just sandy soil from under the turf in my garden. Dactylorhiza do better in boarders than in containers. My container culture is only a compromise if I have to wash cold treated vitro plants and there is no possibility to plant them directly in beds. In a normal winter Dactylorhiza in containers will not be damaged by frost here; but by permanent altering of temperature and moisture.

Thanks for sharing. Those are very hard to get here!!!
