Zinnia is a genus of 20 species of annual and perennial plants of amily Asteraceae, originally from scrub and dry grassland in an area stretching from the American Southwest to South America, but primarily Mexico, and notable for their solitary long-stemmed flowers that come in a variety of bright colors.





Zinnia leaves are opposite and usually stalkless, with a shape ranging from linear to ovate, and pale to middle green in color. The flowers have a range of appearances, from a single row of petals, to a dome shape, with the colors white, yellow, orange, red, purple, and lilac.





Zinnias are popular garden flowers, usually grown from seed, and preferably in fertile, humus-rich, and well-drained soil, in an area with full sun. They will reseed themselves each year. Over 100 cultivars have been produced since selective breeding started in the 19th century.





Zinnia elegans is the familiar species, originally from Mexico and thus a warm-hot climate plant. Its leaves are lance-shaped and sandpapery in texture, and height ranges from 15 cm to 1 meter.





Zinnias seem especially favored by butterflies, and many gardeners add zinnias specifically to attract them.





The name of the genus derives from the German botanist Johann Gottfried Zinn (1727-1759





Cornflower

(Redirected from Bachelor's button)





Centaurea cyanus (Cornflower) is a small annual flowering plant in the family Asteraceae, native to Europe.





It is an annual plant growing to 40-90 cm tall, with grey-green branched stems. The leaves are lanceolate, 1-4 cm long. The flowers are an intense blue colour, produced in flowerheads (capitula) 1.5-3 cm diameter, with a ring of a few large, spreading ray florets surrounding a central cluster of disc florets.





In the past it often grew as a weed in crop fields. It is now endangered in its native habitat by agricultural intensification, particularly over-use of herbicides, destroying its habitat; in the United Kingdom it has declined from 264 sites to just 3 sites in the last 50 years. It is also however, through introduction as an ornamental plant in gardens and a seed contaminant in crop seeds, now naturalised in many other parts of the world, including North America and parts of Australia.





The Blue Cornflower has been the national flower of Estonia since 1968 and symbolizes daily bread to Estonians. It is also the symbol of the Estonian political party, Rahvaliit, and the Swedish political party, Folkpartiet. The Cornflower is also often seen as an inspiration for the romantic symbol of the Blue Flower.

Are Zinnias and Blue Bachelor Button perennial?
They are annuals, although I do have a perennial bachelor button but I am sure it is not the one you mean. My annual bachelor buttons self seed and come up by the dozens each year and I encourage this by tossing their seeds, after I dead head, all around where I want them next year. I also do this with Cleomes.
Reply:My bachelor buttons came back this year. I have pink, blue, and white, and they are cross breeding.
Reply:Bachelor buttons are perennial, and zinnias are annuals.
