I am unable to visit UBCBC but a have a photo link of one of the plants there, Hydrangea Heteromalla: http://commons.wikimedia.org/wiki/File:Hydrangea_heteromalla_form.jpg Does anyone know roughly how tall this plant is (i am assuming it is mature). I have a Hydrangea Heteromalla "Bretschneiderei" which I inherited with a house I just bought and its only two years old and 50cm high and I'm trying to get a real world idea of how large it might get ... the books seem to refer to each other! Thanks.
