 One form of the plant , T. grandiflorum f. roseum , opens with light pink petals instead of the common white . It is generally found very rarely throughout the range , but in the Blue Ridge Mountains of Virginia is can be found somewhat frequently in mixed or sometimes pure colonies . It should be noted that the white flowers of the common pure white variety of T. grandiflorum turn a very distinctive pink and remain so for several days just prior to the wilting of the flowers . Plants bearing these pink flowers are often mistaken for a " pink variety " of trillium .
