What it sounds like you’re looking for is Magnolia liliiflora:
" ‘Ann’ is the favorite of Michael Dirr (author). Other cultivars include: Betty, Jane, Judy, Pinkie, Randy, Ricki, & Susan. Dirr says, “The flowers open before the leaves and make a magnificent display. Again in summer, sporadic flowers occur but are lighter colored owing to the heat. They root easily from softwood cuttings and have been successfully flowered at the Minnesota Landscape Arboretum (Zone 3) and Athens, GA (Zone 8).”
Ann: 8 to 10’ height, 10’ wide, more open than Betty, deep purple-red, 7 to 9 petaled, slightly earlier than Betty… good grower."
Magnolia kobus: 30 to 40’ high. “The species is hardy in Zone 4, the variety in zone 3.” Magnolia kobus var. borealis
Magnolia acuminata (zone 3 to 8). Not showy flowers at all and a large tree. I’ve seen these in flower and while the leaves are large and the tree is lovely, it should not be grown for its flowers.
