At about 10–15 years of age the stem stops growing and produces a flower spike with white, lily-like perfumed flowers, followed by coral berries. Soon a crown of terminal buds appears and the plant starts branching. Each branch grows for about 10–15 years and re-branches, so a mature plant has an umbrella-like habit. It grows slowly, requiring about 10 years to reach in height, but can grow much faster. Despite being a monocotyledon, it still has annual or growth rings.
