Do Cordylines grow in full sun?

Some Cordylines prefer full sun like C.'Maize' and C. 'Roosters Tail'.  Most Cordylines prefer a a semi-shaded position with good light and some protection from the hot sun.  Many varieties will however tollerate a sunny positon but they'll take longer to establish and will not always have their best colour.  Cordylines with purple and orange tones tend to be more sensitive and require a well shaded position with protection.
