hi. i was wondering why plants like crowberry have green leaves (or needles). i understand they contain corotenoids (accessory pigments) etc but it must be some kind of adaptation the plant has. also, why do they (crowberry) appear to grow facing north, ie. where light intensity is less than facing south. why is this?

thanx

does anybody have a better answer?

let me reformulate my question:

Why are a lot of carotenoids found in shade plants?

Have a look at:

Carotenoids can function as acessory pigments to scavenge energy not
immediately useful by chlorophylls. A shade plant with a lot of
carotenoids (or other pigments) may be trying to use what light it
receives as efficiently as possible.

You mean carrots really can see in the dark?
