The tree blooms at a young age, with the slightly fragrant wide flowers covering the bare plant in late winter or early spring before the leaves appear. There is natural variation within the flower color, which varies from white to rich pink; the hue of pink magnolias also changes from year to year, depending on day and night air temperatures prior to and during flowering. The flowers are star-shaped, with at least 12 thin, delicate petal-like tepals, some cultivars having more than 30.
