Corydalis nobilis - Siberian corydalis

Siberian corydalis is one of the old perennials flourishing in manor and parsonage gardens. It can also be found in the Mustila manor park, as well as in the Juhlapaikka (Festival area) and Atsalearinne (Azalea slope). Besides gardens, it may be seen as garden escapes in herb-rich places around old settlements. Ants disperse the seeds efficiently while using the elaiosomes attached to the seed as nourishment.

The corydalis found in Finland originate from Sweden, from the Hammarby estate of Carl von Linné. He had seen a drawing of an old-fashioned bleeding heart (Lamprocapnos spectabilis) and asked his Finnish student Erik Laxmann to send over some seeds. The seeds were sent from the Ob valley in 1765, but these seeds produced Siberian corydalis, not the old-fashioned bleeding heart which Linné to his disappointment never had the chance to see.

The Siberian corydalis looks at its best in early summer, especially when blossoming in May, when the blue-green foliage is still lush. The flowers are yellow with a brown dot. As the seeds ripen the plant withers and eventually completely disappears as the summer moves on. Corydalis is best placed among late flourishing plants which take over the space after the Corydalis has disappeared.
