Hi GW. I bought my Sarracenia plant this spring and have been growing it very nicely. The only problem, is that the pitchers don't have any liquid in them. I have been a "good boy" keeping it watered, and much better than my Nepenthes. My Sarracenia has many pitchers yet my Nepenthes has acid and my Sarracenia doesn't.

This is what my Sarracenia looks like:

but the picture isn't mine. It belongs to Plu604 from proboards.com

Is this species supposed to have liquid, or is it supposed to be dry? If it's not supposed to be dry, what do I do?
