But I'd cut it off, now!

Unless you want a common old red shrub rose bush. That little sprout will choke off the life of your larger tree quicker than you would believe, and leave you with a common red shrub rose that can take years to get rid of.

I've got one that grew back from a tea rose that died from being flooded, and I am still trying to get rid of the thing twenty one years later.
