Changing position of Textarea placeholder

Hello,

First off let me say thanks for the great plugin!

My form is located at https://scottgardinertech.com/jenngoren/contact/

I want to center the placeholder in the textarea vertically. Is there any way that I can do so without disturbing the alignment of the placeholders in the text fields?

Thank you.

Scott.
