Totally forgot I had a pot of this stuff hidden in the garden (overgrown by a large shrub!):
This is about a 25cm shallow pot. *Mostly sand/peat mix (looks like some bird poop as well!). *
To give you an idea of the tuberís hardiness... I did not water it at ANY stage through the summer. And it was a dry summer!
As my garden is very protected these usually sprout earlier than the wild ones, so this is my indicator to head up to the folks place and see whatís happening out in the fields.
