DENDROLOGY

Detailed explanation-1: -Trees and shrubs, including all gymnosperms (cone-bearing plants), are perennials, as are some herbaceous (nonwoody) flowering plants and vegetative ground covers.

Detailed explanation-2: -A perennial plant or perennial flower is a non-woody plant that lives for more than two years. Perennials, especially small flowering plants, grow and bloom each season and then die back, returning the following year from their root stock rather than seeding themselves the way an annual plant does.

Detailed explanation-3: -What is a perennial plant? Unlike annuals, which live for just one season, perennial plants live for more than two years – their Latin name means ‘through the years’. Strictly speaking, trees and shrubs are perennials, but we tend to refer to perennials as long-lived plants.

Detailed explanation-4: -Bamboo is a perennial flowering plant with a distinctive life cycle: many bamboo species remain in the vegetative phase for decades, followed by mass synchronous flowering and subsequent death.
