Plant health -- or lack thereof

I try to avoid looking at it. Because every time I see it I am racked by guilt. Every day when I arrive to work, there it is -looking forlorn and woefully neglected: My plant.

It started as a vibrant, hot pink petunia. Now, it's not much of anything. Just look at it. I haven't seen the semblance of a flower in months. And just last week I cut nearly all of its stems and leaves off.  It seemed only right. They all had evolved to brown crisps. "Help me!" the plant seemed to be saying. I suppose I could have watered it a little more. OK, a lot more.

My tragic neglect of the plant has given it a staunch following. People around here check up on it daily. They leave shaking their heads. Because despite my desperate attempt to resuscitate it, the plant never shows marked improvement. In fact, I'm not convinced it's still a flowering plant. But those in the know assure me it's definitely not a weed.

I will continue to work hard to bring it back to life. All I can do is keep watering it, I guess. Unless you have better advice? I welcome your feedback. Help me help my plant.
