Liriodendron tulipifera - Tulip Tree A magnificent specimen tree for a park or very large garden, Liriodendron tulipifera is a large, fast-growing, long-lived tree with a broadly conical outline. The leaves are bright green and shiny with a very distinctive shape, lobed but with an almost squared-off end; they turn rich yellow in autumn. The flowers are enormous, green and orange and tulip-shaped, hence the common name Tulip Tree. The flowers appear in July, more prolifically in warmer areas, but the tree does not flower until it’s about 25 years old. Holds the RHS Award of Garden Merit.
