Centennial Star Magnolia

Centennial Star Magnolia (Magnolia stellata 'Centennial')

Centennial Star Magnolia (Magnolia stellata 'Centennial') is a vigorous, showy cultivar of the star magnolia known for its abundant early spring flowers and larger-than-average size. Bred to commemorate the 100th anniversary of the Arnold Arboretum, 'Centennial' delivers an impressive display of white, star-shaped blooms flushed with pink and brings seasonal drama to both formal and informal landscapes. Its elegant branching structure and reliable bloom make it a standout in spring gardens.

Distinctive Features

'Centennial' is prized for its profuse, fragrant flowers with 28 to 33 narrow petals each, creating a fuller, more dramatic floral show than typical star magnolias. The blossoms emerge in early spring, just before or as the foliage begins to unfold, offering a striking contrast to the bare branches. This variety grows larger than most M. stellata types, reaching 20 to 25 feet tall and wide with a rounded, upright form. The medium green leaves turn golden-bronze in fall, adding multi-season appeal.
