'Sun Spire' Magnolia is another lovely introduction by the late Dr. August Kehr. The flowers are deep yellow and held upright on the branches. Since they appear late in the spring after the danger of frost, the display is consistently showy, like a tower of fat yellow candles. The habit is distinctly upright, making Magnolia x 'Sun Spire' is a great candidate for smaller gardens and tight spots. The parents are M. x 'Woodsman' and and M. x 'Elizabeth'.
