Rhizomatous describes a growth habit, not a specific plant. A rhizome is a thickened underground or partially underground stem that creeps about and sends up shoots.

The ginger you see at the grocery store is a rhizome.

I saw it was native to the Eurasian Continent.

Bearded Iris are rhizomatous, as are Louisiana and Spuria Iris, but a large number of iris are bulbous rather than rhizomatous.

I've got the rhizomatous ones in my yard, and you can't get through those roots even with a pitch fork. Amazing plants.
The delicate native wild roses here are the same, although the roots don't grow in a solid brick mass. They reach horizontally and occassionally send up a shoot to start a new plant. I tried transplanting a couple one time and ended up with three feet of root.
