The rate of growth of Udo (Aralia cordata) from Japan is phenomenal in cool spring weather, even outgrowing Hablitzia tamnoides (Caucasian spinach)!
The first picture was taken by Christian Odberger during my permaveggies course and just two weeks later the plant is taller than me! The view is or less the same and the apple tree at the back is now in full bloom! The fern is ostrich fern.
