Re: Corydalis and dry shade
Hello Cindy,
Bobbi pretty much has it right here.... C. lutea will tolerate a bit more
moisture and richer soil than the C. ochroleuca, but not a whole lot. I have one
that has moved from the rocks to the upper level of the garden where there is
better soil..... but. It is in root competition, raised area, and sits on top of
the soil in leaf mold.
Rocks, gravel, tucked into stone walls....... plenty of light but not direct
sun. They can get brown during a prolonged period of no rain, but bounce right
back when moisture returns. Both foliage and bloom production.
