Please can I clarify which plant you are asking about. Cordyline or Lobelia cardinalis? Also where you live ...approximately...as that will reflect the answers you get.
Ah In that case, no, shouldn't be necessary unless it's tiny and vulnerable, but it's wet cold that does for them here. Up against a house wall should be fine.
It's a place where beautiful isn't enough of a word....
I live in west central Scotland - not where that photo is...
