Glaucidium palmatum 'Album'



1st May 20216


Glaucidium palmatum is a very select Japanese perennial woodland poppy. I have grown it badly once before, but I only know one garden where it seems to be prospering. As far as I can tell it requires light shade and warm summer temperatures to grow.
I was given a piece of rhizome of the white flowered form imported from Japan. I'm not entirely sure what conditions Glaucidium requires when dormant but I have a strong suspicion that it doesn't want to have its roots removed, its rhizome dried, chopped to pieces and then posted half way around the world. I wasn't very hopeful but it produced a decent leaf and didn't flower, which was a good sign. I thought that perhaps it would make some new roots and that possibly in a pot in the Alpine House it would establish well enough to force me to consider a longer term option.
Not so, it died without producing any new roots.
Traditionally in Japan the dried roots are sold to foreigners to demonstrate how stupid they are.
