They are NOT the same plant. The Rubin is much, much larger and has leaves that are usually, but not always, alternate. It may be a hybrid of some kind. Working on that...

The Red is apparently a form of L. palustris that's smaller, opposite-leaved and is very easy to keep red. Rubin can get more of a maroon if conditions are good, but intensity of color between the two can be approximately equal.
