I was gven a few seeds for unusual (to Southern Ontario) Magnolia seeds; I scarified them, potted them, planted the seedlings in a holding garden then transplanted them to Prince Edward County. Now, about 12 years later, I get flowers every year from these trees.
Magnolia acuminata, Cucumber Magnolia, has beautiful yellow flowers mid spring. They have a slight citrus scent and I call it my Lemon Magnolia. Magnolia tripetala (Umbrella Magnolia) is likely poorly situated, being in the middle of a copse of Maple and Ash, but it too has flourished, this year producing a dozen or so spectacular, huge creamy blooms. They start out looking like fat candles, standing straight up from the vortex of leaves, before the outer papery shell falls away t reveal the petals
