Wilting Galinas

[hunter]

I've got a Galinas exhibiting a wilting that I can't figure out. Here's a pic:

Basically this plant wilts at the top for most of the day. It looks simply pathetic. It actually looks better than normal in this picture. In the morning it perks up and looks pretty good.

We recently had a few storms move through here, so I thought it just might be a severe case of environmental stress. I can't find any obvious damage to the plant.

Is there some disease that could cause this wilting scenario? I first noticed this plant's sad shape on Saturday. I went ahead and staked it to help remain more upright, but it still wilts by afternoon. All other plants are fine.

Thanks!
