Climate diagrams

The diagrams of climate of Cypripedium habitats not only show duration and intensity of seasonal humidity and dryness. You can also see the total water balance of the habitats by correlating 10°C with 20 mm of rainfall.The vertical distance of the curves indicates the intensity of dryness (red area) and humidity (green area).

Habitat diagrams

Comparing the diagrams above with those of your place (Frankfurt/Germany in my case) it becomes clear what you must do. For me cultivation in the garden can only be successful with special care - watering in summer and protection from rain in winter. In 2001 May and June have been much too dry here and December, January and February too warm with heavy rain instead of snow. So the substrate was too wet. More sensitive species suffer enormously from such climatic conditions.

Few species only have different requirements with regard to climate.
