Stinky Plant

There is a plant which is the best yet the worst plant in the garden.  Between the front & back yard, there are 5 large bushes of it.  It is herbaceous, with a woody stem on the old growth.

Lovely... but beyond gross!

Pros:
- Hummingbirds LOVE LOVE LOVE this plant.  Its bright red-pink flowers attract them like nothing else, and they are constantly in the backyard, nearly ignoring the hummingbird feeder.
- Let's not forget that bees & bumblebees (and carpenter bees in the front yard) love it just as much... and with honeybees in decline, it's considered a good deed to keep them happy.
- It is quite lovely, with thick fresh green foliage and a plethora of flowers.
- Drought-resistant!
- Growth is astounding, so cutting it back once a month (or more!) is necessary to keep it from going crazy.  Never have I encountered such a vigorous plant.  Cutting it so frequently has literally made a constant supply of fresh flowers since late winter.

Cons:
- It has the most offensive smell of any plant I have ever smelled, hence the nickname Stinkyplant.  My husband agrees!  The smell isn't so bad when you're next to the plant, but if your clothes rub it the scent becomes overpowering.  I can't continue to wear contaminated clothing, and being stuck in the limited air space of a car with contaminated clothes is pretty horrific. 
- Growth is astounding.  No matter how much I cut it back, it is always encroaching into the places where we need to walk, so it is easy to brush up against it.  I have measured 6" of growth in a week after a chopping.  I would kill this thing if it was allowed (we're renting) and if the wildlife didn't love it so much.

I wish every plant grew as easily as this one.

My mother-in-law has suggested that it is a type of salvia, but I cannot find anything on it.  I'll bring it in to work next time to see if either of my coworkers might know what it is.

Do you know?
