The palm fronds used for the procession of Jesus into Jerusalem on the original
Palm Sunday would most likely have come from the
date palm (Phoenix dactylifera). There were and are other types of palm trees in the Near East, but the date palm had the most day to day significance for the people of the area because it provided a staple food in their diet, and largely because of that the date palm also acquired symbolic significance for them. Date palm fronds were associated with peace and victory, and when Jesus rode into Jerusalem on the back of a donkey – the mount of a king on a mission of peace – the symbolism of the moment for was complete.
Since the first Palm Sunday, Christians around the world have celebrated with whatever plant branches were available locally without getting hung up on
absolutely having to use palm fronds, which in any event were not be had in cold climates in the days before large scale international trade. It is only relatively recently that palm fronds harvested in southern Mexico and Guatemala from the
parlor palm (Chamaedorea elegans) have been shipped great distances for Palm Sunday celebrations in areas where palms do not grow.
Some Christians have struggled with whether harvesting fronds from
wild plants in the rainforest and shipping them halfway around the world for a once a year celebration makes sense
environmentally and economically. There is irony, too, in that the common name – parlor palm – for the type of plant growing in the understory of the Guatemalan rainforest tips off its other use, which is as a quite popular houseplant. People in colder climates who are determined to use palm fronds to commemorate Palm Sunday rather than any locally grown foliage could very easily grow the plant they are used to in their own parlors. Since parlor palms usually grow to four to six feet, and eight to ten feet at most, they would be much easier to accommodate in the average living room than a date palm at 75 feet, nice as it would be to have the dates at other times of year.
