Yes! But modestly, not aggressively. In perhaps 20 years, my plant's suckers and shoots haven't expanded the plant's area by more than a foot or two. I have no patience with imperialistic roses or other plants; but 'Portlandica' is absolutely no problem at all. It's a very lovable variety, in my estimation.

At the risk of repeating... Here's the Comment:

It has been thought for a long time that the Portland roses had the china rose as a parent.

A recent survey from the university of Lyon (France) has shown there is no China parentage in "Duchesse de Portland".

The link is http://www.rosarosam.com/story/story_HP00.html

Having worked with breeding the Portland Rose, I too would say that there is no China rose in its background.

Quite right. After being told for decades that the Portland Rose was something like ((Autumn Damask x some gallica) x some China, probably Slater's Crimson), DNA tests have shown that it has no China ancestry at all. See, for example, The Rose: An Illustrated History, by Peter Harkness, 2003, p. 131.

I guess this is either not new information or it has recently been confirmed do to genetic testing. Graham S. Thomas in the 1994 edition of his 'Rose Book' has a footnote regarding the 'Portland Rose',

"It is now considered that the parents of the 'Portland Rose' were R. gallica and R. damascena var. semperflorens and they owe nothing to R. chinensis"
