Saucer Magnolia
Magnolia × soulangeana
Family Magnoliaceae
Saucer magnolia opens huge pink-and-white goblets on bare branches in earliest spring — a display so extravagant that traffic genuinely slows for it. It blooms before almost anything else in the yard dares to, which is both its glory and its one gamble.
The gamble is a late frost, which some years browns the open flowers — in frost-prone hollows, the later-blooming 'Jane' and 'Ann' hybrids dodge it. At twenty to thirty feet with a broad, low canopy, it fits real yards. When the bet pays, nothing in spring compares; place yours.

Edibility, identification, and traditional-use notes here are general reference — not medical or veterinary advice, and not a claim that any plant treats or prevents anything. Medicinal ratings record how strongly a plant features in herbal tradition, nothing more. Never eat or dose a plant you have not positively identified. More on how to use this library.

Questions
Saucer Magnolia questions, answered straight.
Is saucer magnolia safe for kids and pets?
Saucer Magnolia is commonly eaten and isn't considered toxic, but "commonly eaten" isn't a guarantee for any particular person or animal — allergies, quantity, and which part you eat all matter. Never eat a plant you haven't positively identified, and check with a vet before letting pets or livestock graze anything new.
