‘Designer Genes’ is incredibly striking in the spring as the brilliant yellow leaves emerge from contrasting deep wine red shoots. It quickly grows to form a medium sized mound of bright yellow leaves with showy bright red petioles. Compared to other yellow hostas, this variety holds its coloring longer. Later in the season, the foliage mellows to more of a chartreuse green color. Tall, red scapes carry the purple flowers in late summer.
