I design and create our wreaths at HHGDecor with premium quality materials so the wreath will last for years to come.  Further, I coat each finished wreath with a UV protective spray to extend the wreaths longevity.  (I’ve heard back from customers from 6-years ago that share their wreath still looks wonderful).  I do recommend displaying outdoor door wreaths in a covered area.  Direct exposure to rain, snow, etc. can reduce the life of the wreath.
