Sweetbay Magnolia is an ancient understory tree that is native to the Southeastern United States. It has lustrous, leathery dark green leaves with silvery undersides that are deciduous to semi-evergreen. The creamy white flowers bloom from the end of May into June with a lemony-sweet fragrance that shouldn’t be missed, and continue to bloom sporadically until September. They are pollinated by beetles and followed by an aggregate fruit of follicles with bright red exposed seeds. The seeds are covered in a fleshy, high fat exterior that provides food for many small mammals and birds, especially those seeking high-energy food sources for southern migration. The foliage of Magnolia spp. hosts at least 21 species* of Lepidoptera, including the Eastern Tiger Swallowtail butterfly.
Sweetbay Magnolias prefer moist, acidic soils. They will not thrive in high pH soil and need a steady supply of water throughout the growing season. They make beautiful understory specimen trees, especially gracefully overhanging patios or for foundation plantings. They can be used in shrub borders and on the woodland margins. The roots are fleshy and not wide-spreading, allowing for successful underplanting of ferns and wildflowers which will thrive under the thin, filtered canopy.

Plant Care & Installation Quick-Guide
Proper acclimation and installation are key to your plant's success. Please cross-reference these tips with your plant's specific ID tags:
·
Pre-Planting: Store plants in a light-appropriate area on soil or grass (avoid hot concrete or asphalt) and water daily until the soil is saturated and the pot feels heavy. If temperatures drop below 30°F, move pots to a garage or cover them to prevent root freeze.
·
Installation: Dig a hole matching the depth of the pot, remove the fabric container, and ensure the plant’s crown or root flare is level with the ground. Fill gaps with soil, water heavily, and apply 2 inches of mulch—keeping it clear of the stem.
·
Ongoing Care: Check moisture daily by feeling 1–2 inches into the soil; water deeply at the base if the soil feels dry or warm. Newly installed plants require frequent watering (up to 3–4 times weekly in heat) until fully established, which can take a few months for perennials and up to two years for trees.
