stromboli to dog?

apologies if i've posted this in the wrong section and if it has been asked before.
also, i'm assuming the white rose is a dog rose.
ok, on with the question...

i planted some stromboli roses a few years ago. the flower is red, large and gives a great rose scent.

somehow this year, a dog rose is growing from the crown of the stromboli!





perhaps you can see the 2 different sized leaves in the 2nd photo.

a wild rose growing by itself is one thing. but how can it grow from the "parent" stromboli rose?

over to you pros to answer this riddle.

 

I came on here to reassure you re. roses not generally being toxic to dogs... @wiseowl will probably be far more helpful in answering your actual question!

 

Probably came from below the graft

 

If it's coming from below the graft as Zigs suggests then that flower is possibly from the rootstock your rose is grafted too. When you planted the rose did you leave the graft above ground?

 

vaguely, i remember monty don, a few weeks ago on gardeners world, saying all store bought roses are grafted and to plant them with the graft below ground level. so what he said along with what you said answers my question.

sheal, yes, when i planted the stromboli, i left the graft part above ground.

i don't mind the mix of roses. white and red are a nice colour combination. i'll keep an eye on it and trim back if the white rose becomes abundant.

thanks all for your help.

 

yes, thank you wiseowl. have learnt something new.

 

You will have to prune out the dog rose or it will take over. It will be more vigorous than the grafted rose.

 

If Monty Don is planting roses with the graft underground he is wrong. That is what produces suckers from the rootstock.

I presume you ignored Monty's advice?

 

It protects the graft, it's best to go with what Monty says. It all depends on how much the graft is above ground. If it's just above I'd leave it. Put some compost around it.But get rid of the sucker

 

from the horse's (monty's) mouth: "www.youtube.com/watch?v=uqatn_dykOE&feature=youtu.be&t=734" (starts at about 12:13)

monty says plant the rose an inch below ground level.

anyway, i'll keep an eye on my rose and learn as i go. thanks to all for your help.

 

sheal: "I presume you ignored Monty's advice?"

i planted the roses several years ago and did not know anything. by pure chance, one or two were planted with the graft below ground and one or two above ground. right now, only one bush has the original rose blooming. i suspect some of the others will too. i'll keep an eye to see if any of the "graft below ground" ones also produce off-shoots.

 

I've grown roses for many years @kamchow and the grafts have always been just above soil level. I haven't had issues with suckers so will continue to plant the same way in the future.

Monty Don? I'd take any advice he gives on any plant with a pinch of salt.
