The introduction of Magnolia stellata ‘Centennial’ was made to commemorate the 100th anniversary of the founding of Arnold Arboretum, which began in 1872 and is part of Harvard University in Boston. This cultivar was developed by the arboretum from the star magnolias, native to Japan and hardy to Zone 4. The creamy white flowers of ‘Centennial’ sport many delicate petals, giving the blossoms their “star” look. The fragrant flowers morph in to cone-shaped seed pods, maturing in late summer. The tree can reach 25 feet in height with a spread of about 15 feet and can adapt to a number of soils.
