Distribution: native to north and central Europe
Synonyms: Corydalis solida subsp. solida - Corydalis halleri - Corydalis transsylvanica






Notes: The siliques of Solid-tubered Corydalis ripen in May and June. The seeds are spread by ants and for this purpose they have small appendices that serve as food for these insects. Corydalis solida is widely cultivated and is an occasional garden esape, particularly in southern England. In the Netherlands it is native to the south and introduced and naturalized in other parts of the country.

Corydalis solida is a larval food plant of Clouded Apollo (Parnassius mnemosyne) a butterfly that can be found in mountainous areas in many different countries in Europe. In the Spanish Pyrenees both this flower and butterfly can be found for example in la Sarra (Sallent de Gállego).

Leaves: two or rarely three, broadly linear, lance-shaped, curved, fleshy, shiny
Habitat: shady places, woods of beech or deciduous trees, mountain meadows
Distribution: native to central and southern Europe (Belgium most northern country)







Notes: The flowering stems of Scilla bifolia are erect and unbranched. It grows from a bulb and the raceme bears six to ten flowers. The foliage of Alpine Squill will remain for a short time after flowering and then quickly die back in mid to late spring. This species spreads via seeds and dividing bulbs. It can form large carpets, for example in the northern Bovenrijndal in Germany. In this country Scilla bifolia is on the Red List of vascular plants and legally protected. In the Netherlands Alpine Squill is offered as a garden plant and has naturalized in forest parks. It can be found next to the Siberian squill, a relative that flowers at the same time. Both species are important nectar plants for honey bees in early spring.

Distribution: native to southwestern Russia, the Caucasus and Turkey







Notes: Siberian Squill has drooping, bell-shaped flowers, one to three on a common scape, often several scapes per bulb. After flowering, the flower stems become limp as capsules (pods) mature. At maturity, the capsules become purple and split open, releasing small, dark brown seeds. When the seeds are mature, the leaves wither and the plant goes dormant until the next spring. In the Netherlands the Scilla siberica has become naturalized.
