THE NATIONAL NURSERYMAN 
Hydrangea Aborescens Sterilis 
By Thomds .1. McBelh, Spi'inyfield, Ohio. 
There seems to he some misimderslaiidiii^- in n'^ard to 
Ifydranyea arboresrens sterilis. As I elaim to l»e tlu^ 
first to have ^rown it for the general tiade (although it 
has heen grown l)y tlorists and nurserymen lor flu; loeal 
trade, for over fifty years), 1 thoughf 1 mighf l)e aide to 
give a few intei’esting ])oints as to its history. 
It does not seem to he generally known there ar(‘ two 
distinet varieties of Ilydranyea arborescens, whieh 1 have 
Hydrangea arborescens sterilis 
called for the sake of convenience, II. arborescens slerilis, 
and II. arborescens sterilis grandiflora. 
The first I take to he a sport of H. arborescens and the 
other a sport of II. arborescens slerilis, for the following 
reasons: 
II. arborescens, and II. arborescens slerilis, are iden¬ 
tical except the flower. 
I have seen plants \vith all the gradations from the 
radiate form of II. arborescens, to the compact ones of 
II. arborescens sterilis on the same plant, and, indeed on 
the same stem. 
The difference between II. arborescens sterilis and 
II. arborescens sterilis grandiflora, is in the latter the leaf 
is heart shaped and the pitiole is longer, the individual 
floret is larger, the time of flowering is about a week 
earlier, and the stems are longer and more slender, which 
makes it more liable to fall with the w^eight of the 
flowers. 
This is the variety Mr. E. G. Hill registered as II. 
grandiflora. My reason for thinking 11. arborescens 
grandiflora is a sport of II. arborescens sterilis is, I had 
a plant of the latter that threw' up a stem that flowered 
and was a complete counteipart of arborescens grandi¬ 
flora. IIow' they propagate in nature I don’t know'. 1 
have seen them under natural conditions growing side 
by side. 
I consider the H. arborescens sterilis by far the better 
for landscape w'ork on accouid of its more upright and 
compact habit.
