We all know that we need to give enough light to the plants to get them to grow well and to have good color. What I've noticed recently, though, is that certain plants that normally take on deep red colors (flava all red, purpurea, etc.) seem to be kind of green when given all day direct sun. Late in the growing season I shaded them more and got the nice deep red colors out of them again. I'm wondering if this is what other people experience as well.

I did notice that my purpurea got a deep-deep red in the late fall, but i didnt change the lighting like you did. Perhaps is some sort of preparation for dormancy?

It's generally well established that maximum sun brings out red colouration.
You'll never get flava var. atropurpurea to turn red in the shade.

What I'm talking about is that they were getting all day direct sun every day. The change was when I moved it to all day direct sun except for about 2 hours around noon. |

A lot of sarracenia get stronger colouration as the pitchers age, and I suggest that this was merely a coincidence, rather than cause-and-effect. If you want to prove anything beyond this then you'll have to do a proper test this year, growing plants of the same clones in the same conditions, apart from the one factor you're testing (ie the hours of daylight). Only when you have two plants (or better still, two groups of plants) exhibiting a noticable diffence between them at a given time, where the only cultural difference has been the amount of direct sunlight they get, will you be able to change people's minds on this subject. |

In my experiences with S. flava atropurpurea, the pitchers get more color with age, as well as good full direct sun. Younger, immature plants seem to take on the characteristics of the classical "heavily-veined" S. flava in strong lighting, with maroon coloration slowly spreading and encapsulating the pitcher as it matures...
I'm also a firm believer that increased amounts of tannins in the growing media can enhance this coloration process to occur more rapidly as well, and lead to darker and richer overall coloration, a phenomena that I've witnessed on native stands of S. flava atropurpurea in the Fl. Panhandle many times over the years.
It seems that the plants that are growing in the areas with the highest amounts of peat deitris and natural tannins have the richest color, but age plays an important part as well...
Happy Growing!
Brian.

Another factor for color in flava ornata/rubricorpora is how well the plant has established itself in it's growing container. We find after dividing, it may take 2 seasons for the plant to regain its fullest colors. S. alata -black is especially prone to this.
As Brian stated, tannins do seem to be a major contributing factor to tube coloration.
