It seems that recycled large date palms, Phoenix dactylifera, became trendy in the past few decades while vast date orchards around Las Vegas were displaced by urban sprawl. They are stately trees with airy but bold rounded canopies between twenty and thirty feet wide. Mature trees are more than fifty feet tall on single trunks. Varieties with multiple trunks are shorter and rare. The ten to twenty foot long leaves are pinnately compound with folded foot long leaflets, and nasty basal spines.
Each date palm tree is either male or female (dioecious). Orchards are almost exclusive to fruiting female trees with only a few male trees grown separately for their pollen, which gets applied manually. Without male pollinators, recycled formerly productive female trees are fruitless, and therefore not messy.
Date palms may have been in cultivation for nine thousand years! The Judean date palm was grown from seed that was lost in storage for two thousand years, which (until recently) was the oldest known viable seed!
