Many different Geranium species grow naturally in Europe, and in Finland about a dozen species have more or less become established. Many more species and subspecies grow in our gardens. It is easy to understand their popularity: cranesbills are simply beautiful. They are especially suited to summer cottage grounds, since rabbits and deer do not usually like to eat them. Cranesbills attract pollinators from tiny flies to handsome butterflies, to the delight of nature lovers. As the name suggest, Siberian cranesbill is originally from Eastern Europe. It has adapted so well to our climate that it sometimes grows abundantly in the wild as a garden escape. Conversely, cranesbills planted as ornamental plants can be found in parks and gardens.
Endres Cranesbill & Bigroot Geranium
Geranium endressii & Geranium macrorrhizum
Endres cranesbill (name also endres’s cranesbill, French cranesbill), home from the Pyrenees mountains can thrive for a long time without special care. Its flowers are quite large (3–4 cm) and delicately pink and it does not look very much like our cranesbill species. However, it can be confused with bigroot geranium (name also bigroot geranium, Bulgarian geranium, Balkan cranesbill, rock cranesbill), which is rarely planted, but can sometimes still be found in nature. The two species can most easily be distinguished by their leaves: Endres cranesbill’s leaves are pointy-lobed and sharp-toothed, whereas the lobes of Bigroot geranium’s leaves are broad and round-toothed.
