The flowers, which bloom in May to June, are 25-30 cm in diameter and have a perianth of 6-9 oval lobes. The outer lobes measure 12-15 cm in length, while the inner lobes are convex and 15-18 cm long and 7-10 cm wide. The fruit is rounded ovate and pink in color, with pubescent combined leaflets that are 6-8 cm long. The tree is best suited for sheltered sites and provides a tent-shaped crown. With its majestic stature and remarkable features, Magnolia macrophylla is truly a standout among flowering plants.
