Is there any other information on the tag? The only "Kardinal" that I know of (and can find on helpmefind.com) is a hybrid tea. Are they in bloom? Can you post photos?

A good, true red shrub is Home Run.

Yep, that's the one...

Nothing really on the tag as far as root info.

In bloom, I'll try to get a pic sometime here.

I was actually looking for that Proven Winner HomeRun after seeing the Knockout, lol. Read about it here :).

But after seeing the Kardinal...it was what I was looking for

Ah, 'Kardinal Kolorscapeâ¢' is the name. Too new for helpmefind.com, although 'Milano Kolorscape' is listed.

I would send an email to "Forever and Ever" plants and ask. A dead giveaway is to look at your plants and see if there is a large knot at the bottom where the graft union would be, there will also be a spot where the grafted plant was cut off. If there is no large knot, then probably own root.

I didn't want to break apart the pot mass, and they are planted already or I would be doing some snooping on the roots for sure.

I'll try an email, hope they reply

Here's a pic, there's some water drops on the blooms making the appearance off a bit in the pic

Got word from the nursery company...these are own root roses, cool :)

Excellent, great to know! Thank you for the update!
