This seldom seen Japanese climbing Hydrangea is a beautiful ornamental vine that climbs using aerial roots and can attain a height of over 6m. The cultivar 'Roseum' has Heart shaped deep green leaves & pale pink flowers that appear in Mid November for me. It look really great climbing up a tall tree, it does not damage the tree, I have one growing up a Liquidambar tree It needs its roots planted on the shadier side of a tree, also needs moist well drained soil - NOT dry. Very few available,
