Though these are on the secular side of things, as most liturgies don't incorporate them. This was mainly for Europeans, AFAICT.
Not sure how many Christians in tropical countries are doing the tree thing. Though with globalization and mass media, Western practices may be more spreading more places in recent years/decades.
