White and pink, both with a yellow center are the most common colors for these beautiful blooms. They erupt in spring anywhere that they grew the year before or were sewn. The blossoms atop a long slender stem attract bees and make a wonderful display of color. The flowers can be dried for use in arrangements indoors and the plant itself is water friendly and happy in our poor Perth soil, but they can be grown pretty much anywhere.
P. Wilshaw tells us that the yellow center turns dark after the flower has been pollinated thus saving the bees extra work.
