Southern Magnolia
Magnolia grandiflora, popularly known as “southern magnolia,” is a large tree native to the southeastern United States. The tree bears very large, fragrant, white flowers that appear on its thick, tough stems. The flowers are cup-shaped, about eight inches across, and can reach up to 30 centimeters in diameter. The tree itself can reach a striking height of 90 feet.
The blossoms are large with numerous stamens and carpels arranged spirally. They do not produce nectar. However, they attract pollinators with their sweet fragrance and secretions. The flowers produce cone-like seed pods filled with large red seeds.
When these pods open, the seeds fall and hang by silky threads. The blossoms of Magnolia grandiflora open about 9:00 a.m. and then close at night for two to three days. During this phase, it sheds its stamens and then reopens, turns brown, and falls apart. (1, 2)

Tree peonies are multi-stemmed woody shrubs with one of the worldâs biggest flowers that can grow 25 centimeters in diameter. The perennial peonies have blooms that bloom in late spring to early summer. The flower buds of tree peonies do not produce any nectar to attract ants. As the season advances, these buds start to swell and reach the size of a small apple before turning into a flower with the size of a salad plate.
