(Celosia cristata) For bright contrast along the border, this classic shorter cockscomb is an heirloom Amish type from Illinois. Grown in US gardens (brought from Europe) since the 1600s, Thomas Jefferson grew a variety similar to this in the 1700s. In the early 1900s gardeners started a trend - trying to grow the largest possible cockscomb bloom in the smallest possible pot! 12 inches. Full sun. Annual. 50+ seeds.
