I mentioned this plant a few days ago and posted a picture of its flower. I said that I was unsure of its parentage but on checking back in the old records it turns out that this is Sarracenia purpurea x oreophila and it's an Adrian Slack cross from way back.
It's not a plant that impresses with its colour or veining or even its height. But it sits there with its great mouth agape awaiting the arrival of its prey, Boeing 747s These do not come to feed on the nectar too often so for the last 35 years or so Hercules has been somewhat hungry.
I'll recap the photos I posted recently.
2008 the green pitchers are an adult S rubra heterophylla
It just looks like it could use a little more direct sun on the back of its hood there Fred.
Was it positioned so that it was blocked from getting the intense 10am-3 pm sun?
With another look, of course it doesn't help that the pitcher's hood was pressed up tightly against the pitcher directly behind it, even forcing the hood to conform to the rear pitcher's shape, as it opened
Look at the two pitchers on the left in the second rank. Their left side (sunny side) is blushed red and the right side green with a straight dividing line down the back seam. Even the front left pitcher shows the effect on the hood but to a lesser degree.
