It is fairly common, while driving on the Blue Ridge Parkway, to see large numbers of them growing along streambeds going up into coves. The colors are somewhat variable and often change with age.
Nodding trilliums are usually white.
Painted trilliums are white with red rays coming out of the center of the flower. Catesby's and Large flowered trilliums are often white becoming pink as the flowers age. The toad shade trilliums also are pale yellow or maroon.
