I'll submit 2 for consideration, Dynamite, although HMF says that it has a "citrus" fragrance, or Don Juan

Hmmm.... I don't think it's Dynamite, because the blooms are really small and HMF says their 4 inches across. And the blooms of Don Juan look a lot darker.

But thanks for the input.

Check Red Cascade.
I know it was in box stores three to five years ago and has the vigor to be the size of yours coupled with the very small red blooms.
I'm not sure the fragrance matches though.

Red Cascade does seem like a likely choice.
