One of the rarer species, Corydalis omeiensis is actually a little hardier than many others. A chinese species that seems to form tight clumps, typical ferny foliage and masses of purple to deep blue flowers in early summer.
Still requiring dappled shade, this is an excellent species for planting beneath deciduous trees. The autumn leaves will form a natural mulch and Corydalis omeiensis with thrive amongst the leaf mold.
Some gardeners like to cut the plants back in late winter before the new growth commences, however we just leave it to its own devices.
In very dry summers some extra water will be required as Corydalis omeiensis does not like to dry out completely.
