Or in other words, a variegated form of Japanese knotweed. Japanese knotweed, Polygonum cuspidatum/Fallopia japonica, is a virulent spreader, considered by many to be an invasive pest equal to kudzu and equally as difficult to control. The variegated form is only slightly less aggressive, as the photos clearly indicate, spreading by both seeds and underground rhizomes. And it is not a shrub but a herbaceous perennial, dying back each winter but appearing again 3-4 times larger the following spring. Tell your coworker this is not a plant to let loose in the garden :-) If they must have it, container it and deadhead faithfully. Here is a link that might be useful: Fallopia japonica

Suckers would be root stock that has come up on a grafted rose or an own root rose that sends up a shoot from the roots at some distance from the main plant. I think Mad has it right. That's the graft sending up new canes from below ground.

imagardener2 and juneroses Thanks for the fast response. I have wondered what this bush was for several years. Now that it has started blooming it is really an attention getter. Mine is more like a bush with multiple branches but is now probably 12 foot tall and covered with blooms. I don't see that many sulfer butterflys on it but there is an Iguana living in mine. Go figure. Only in South Florida.

Could it be a Maple Leaf Viburnum? http://www.ct-botanical-society.org/galleries/viburnumacer.html Ours are just starting to get buds and are probably 2-3 weeks away from blooming. -Josh-
