"Central Valley" of where?
brazil? texas? alaska? pennsylvania? maine? china?
there are a lot of valleys in the world!
and they all have a center!
all Sarracenia can basically take the same conditions..
with the exception of S. purpurea, which is more cold-tolerant than the others.
*cant* take high temps and a lot of sun?
do you mean you *Dont* have high temps and a lot of sun where you are?
Sarracenia like lots of sun, the more the better!
and can take heat fairly well, if its only a few weeks..
what they DO need however is humidity!
so if you are in a high-sun desert environment, like Phoenix, the dry air will be a concern..
So what exactly is your climate like?
describe your seasons in terms of light, higest and lowest temps, precipitation and humidity, and we can go from there!
