Hybrid ‘Lois’ Magnolia

Arbor walk #90, Treekeeper ID #5902

Magnolia ‘Lois’ is adaptive to the St. Louis region and was introduced in 1998 by the Brooklyn Botanical Garden. It flowers in the Spring with a true pale yellow color and it grows to 30′ tall and 20′ wide.

Magnolia ‘Lois’ is a type of magnolia tree that produces pale yellow flowers that are cup-shaped in the middle of spring. The tree flowers a little later than its relatives, the Magnolia stellata and Magnolia x soulangeana varieties, which helps the ‘Lois’ variety be safer from frost. The tree is primarily used as an ornamental tree and is valued for the flowers, shade, and beauty it provides.
