Evidently you can. Google the Anglegrove Tree Seed Company. They have seeds for several shrub roses, are located in NF Canada.

They claim "Shrub roses produced from seed tend to really thrive as compared with many grafted roses. On the whole they are hardy, vigorous, disease free, long lived and produce a wonderful fragrance."

I found that by googling propagating rosa hugonis

I believe that class of roses is difficult, but not impossible, to propagate by cutting except somewhere I read the spinossima (sp?) are the most difficult if not impossible to root from cuttings.

There must be a special method for planting the seeds which they don't state on their page. If you order seeds, hopefully they give instructions.

i am an amateur propagator. i don't have to worry about productivity and i have no problem propagating spinosissima's from cuttings, but you have to start with a lot of material (cuttings).
i do my cuttings in ver early spring in small pots filled w compost. i count on 20 cuttings per pot (with the objective to end up with at least 1 rooted cutting). i water and put a clear plastic bag over the pots and i put them back outside and forget them until it looks like i shoud water. i take the plastic bag off when i know it won t freeze anymore and whaterver survives this treatment usually makes a wonderful shrub (can t be in a rush though!).
worked fine this year for canary bird, spring time...

try the following link

It is about hybridizing but it also tells you how to grow from seed if you watch the entire slideshow. Good luck.

I remove the seed from all other debris and sprinkle them into plastic containers on moist sand that are sealed and stored in a dark storage unheated shed. every spring I examine the containers (labeled with the name) looking for signs of germination and prick out the ones that have started to root. Some take a year, a few have taken up to 3 years.

I never put my rose seeds in temps under + 10 C -if so they go into seeddormancy and can take up to 2 years to germinate
