Pine trees are remarkable evergreens, known for retaining their needles for roughly two years before shedding and regrowing them—a process that keeps these trees lush year-round. Pine needles vary widely in size, from 1 to 11 inches, depending on the species. Both male and female pine trees produce woody cones, but each has a unique role: females produce seeds while male cones release pollen. These resilient trees can reach heights anywhere from a modest 4 feet to towering 150 feet.
