Yellow Bird Magnolia in a 2.5" Pot. 1 Yellow Bird Magnolia 6-12" in a 3" pot. The Yellow Bird Magnolia has large bright canary yellow flowers that appear more often than other magnolias because they emerge with foliage late in spring after danger of frost. This fast growing magnolia is perfect for a single specimen plant or exceptional when combined with other plants that offer summer flowers. The Yellow Bird Magnolia grows in acidic loamy well drained soils. It needs full sun to partial shade meaning it prefers a minimum of 4 hours of direct sun light each day. These usually reach heights of 6-8 feet tall. Hardy in zones 5-9. Planting instructions included with every order. California orders ship bare root due to soil restrictions and only ship when dormant late November-March.
