Design IdeasThough technically a tree, grow this big flowering Magnolia as a large shrub. It is a perfect size for foundation planting against dark walls or beside windows where you can enjoy the flowers at close range. Integrate into flowering shrub borders or use as an accent among perennials. Make it the focal point of a smaller city garden, where you can carefully control the shape for night lighting and visibility. Such large softly colored blossoms make a great study up close around patios, porches and other outdoor living spaces.

Companion PlantsLooks beautiful in an early spring border with such flowering shrubs as Spring Glory Forsythia (Forsythia x intermedia 'Spring Glory'), Double Pink Bridal Wreath (Spiraea x bumalda 'Anthony Waterer'), Super RedTM Flowering Quince (Chaenomeles japonica 'Moned') and the early flowering Mount Baker Canadian Lilac (Syringa x hyacinthiflora 'Mount Baker'). Top it off with Pink Japanese Wisteria (Wisteria floribunda 'Rosea') or the potent magenta Ernest Markham Clematis (Clematis x 'Ernest Markham').

Follow a regular watering schedule during the first growing season to establish a deep, extensive root system. Watering can be reduced after establishment. Feed with a general purpose fertilizer before new growth begins in spring.
