Corydalis nobilis (Siberian corydalis) is a perennial plant native to Siberia, Xinjiang and Kazakhstan. It was introduced to Europe by Linnaeus, who had asked his friend Erich Laxmann for seeds of Lamprocapnos spectabilis (old-fashioned bleeding heart), but was sent seeds of C. nobilis instead. Both Lamprocampnos and Corydalis are members of the Papaveraceae family, with seeds having an attached elaiosome that makes them attractive to ants, which disperse the seeds.
The seeds of C. nobilis typically have elaiosomes (a fatty body attached to the seed but not part of it, which can be eaten by ants without harming the seed within.) Seeds of C. nobilis are dispersed by ants, who carry seeds away to feed on the elaiosomes. Myrmecochory (seed dispersal by ants) is also observed in other Fumariaceae and has evolved independently in many other plant genera as well.
C. nobilis, first described based on seeds sent to Linnaeus from Siberia, is now dispersed as an ornamental plant. It prefers moist soil in spring, drier in summer, and does well in full sun or partial shade. It is very hardy.
Association with Linnaeus
Linnaeus had seen a drawing of Lamprocapnos spectabilis (old-fashioned bleeding heart) in the thesis of a Russian student who was describing many Siberian plants. He longed to see a living specimen of this flower for himself. In 1765, he was delighted to receive seeds from Siberia that he thought would grow into bleeding heart plants, but the seeds were instead for a different member of the Fumariaceae family, C. nobilis. The seeds were sent to Linnaeus by his friend Erich Laxmann; they originated from a Siberian mountaintop in the northwestern Altai Range. They had not previously been known in Europe.
Seeds of C. nobilis spread throughout Europe from Linnaeus's garden in Hammarby, reaching England's Kew Gardens in 1783. After the death of Linnaeus, C. nobilis self-seeded throughout his garden, becoming a weed.

"Seeds of Siberian corydalis which he received from Erik Laxman (sown in 1765 in Uppsala, Sweden) were believed to be the much sought after Fumaria spectabilis, but turned out instead to be a new species, a species that today are common wild from Linnaeus' garden in the parks around Uppsala."
