Ginkgo biloba If you want a tree with yellow fall color, ginkgo is guaranteed gold. The emerald green leaves suddenly turn a bright yellow as the days cool. Then they drop all at once, spreading a golden carpet on the ground. Though this tree grows slowly, it becomes more beautiful as it ages, so be patient. Place in a location with deep, loose, well-drained soil.Female trees produce foul-smelling fruit, so plant only named male selections.
