Magnolia × soulangeana, commonly known as saucer magnolia, is a deciduous hybrid magnolia (M. denudata × M. liliiflora). It is the most commonly grown deciduous magnolia. It is a broad shrub or small tree that typically rises to 20-25’ tall with a rounded crown. It is often grown in a multi-trunked shrubby form. It typically matures over time to 20-30’ tall and as wide. Fragrant flowers (to 8” across) bloom in early spring before the foliage emerges. Flowers are pink with white interiors. Saucer magnolia is the most popular deciduous magnolia in cultivation today, with a large number of hybrid cultivars now available in commerce featuring flowers in various shades of white, pink, rose, purple, magenta and burgundy. Hardy in zones 4-9.
Growing Instructions for the Saucer Magnolia
The seeds have a period of dormancy and need to be cold stratified to break their dormancy. The seeds are stored in a refrigerator so they have already been stratified. The seeds need to be planted when received or stored in a refrigerator until they are planted. 1. Scarify the seeds by nicking or sanding the seed coat. The seeds can be sanded with sandpaper, a nail file or an emery board. 2. Soak the seed in water for several hours. 3. Place the seeds in a plastic bag and seal it. Store the bag in a refrigerator for two months. 4. Fill a pot with potting soil. Use a pot that has drainage holes in the base. 5. Sow the seeds on the soil and cover them with a thin layer of soil. 6. Water the container and leave it to drain. 7. Put the pot in a warm, sunny area. 8. Water the pot regularly so that the soil is moist but not wet. 9. The seedlings can be transplanted when they are a few inches tall.
Seeds are stored in a refrigerator to maintain viability.
