Saucer Magnolia Growing Conditions – Caring For Saucer Magnolias In Gardens

By Darcy Larum, Landscape Designer

Shortly after the Napoleonic Wars in Europe in the early 1800s, a Calvary officer in Napoleon’s army is quoted as saying, “The Germans have encamped in my gardens. I have encamped in the gardens of the Germans. It had doubtless been better for both parties to have stayed home and planted their cabbages.” This Calvary officer was Etienne Soulange-Bodin, who returned to France and founded the Royal Institute of Horticulture at Fromont. His greatest legacy was not actions he took in battle, but the cross breeding of Magnolia liliflora and Magnolia denudata to create the beautiful tree we now know today as the saucer magnolia (Magnolia soulageana).

Bred by Soulange-Bodin in the 1820s, by 1840 the saucer magnolia was coveted by gardeners around the world and sold for about $8 per seedling, which was a very expensive price for a tree in those days. Today, the saucer magnolia is still one of the most popular trees in the U.S. and Europe. Continue reading for saucer magnolia information.

Saucer Magnolia Growing Conditions

Hardy in zones 4-9, saucer magnolia prefers well-draining, slightly acidic soil in full sun to part shade. The trees can also tolerate some clay soils. Saucer magnolia is usually found as a multi-stemmed clump but single stem varieties can make better specimen trees in gardens and yards. Growing about 1-2 feet per year, they can reach 20-30 feet tall and 20-25 feet wide at maturity.

Saucer magnolia gained its common name from the 5- to 10-inch diameter, saucer-shaped flowers it bears in February-April. Exact bloom time depends on variety and location. After saucer magnolia’s pink-purple and white blooms fade, the tree leafs out in leathery, dark green foliage that beautifully contrast its smooth gray bark.

Caring for Saucer Magnolias

Saucer magnolia does not require any special care. When first planting a saucer magnolia tree, it will require deep, frequent watering to develop strong roots. By its second year, however, it should only need watering in times of drought.

In cooler climates, flower buds can be killed by late frost and you may end up with no flowers. Try later blooming varieties like ‘Brozzonii,’ ‘Lennei’ or ‘Verbanica’ in northern areas for more reliable blooms.
