Common corydalis or bird-in-the-bush.

The common corydalis or bird-in-a-bush (Corydalis solida) flowers before the leaves spring out on trees, filling out the white-yellow-blue colour range with violet hues. The rarer Corydalis species, the intermediate corydalis, is also violet; the two can be distinguished by their leaves – the bracts of the intermediate corydalis are whole, those of the common corydalis deeply lobate. Some more about the leaves: the larvae of the clouded Apollo butterfly (Parnassius mnemosyne) feed on them. Keep watch where the plants grow, after their flowering you may see these rare butterflies around.
