Ponderosa lemon trees are slow growing but can eventually get to over 15' tall. They can produce both flowers and fruit at the same time. Flower buds are uniquely purplish-white and fragrant. Full sun to part sun. Evergreen. Technically not a lemon, but rather a hybrid of a lemon and a citron. It is large and light yellow or green. Strikingly large fruit with thick, bumpy outer skin.
