Zinnias are a genus of twenty species of flowering plants of the Asteracea family. However more than one hundred different varieties have been cultivated since crossbreeding them began in the nineteenth century. Zinnias, which is also its botanical name, are native to the scrub and dry grasslands of southwestern United States, Mexico and Central America. Noted for their long-stemmed flowers that come in a variety of bright colors, Zinnias are named for German professor of botany Johann Gottfried Zinn (1727-1759).
A perennial flowering plant in frost-free climates, Zinnias are an annual everywhere else. With leaves opposite each other, their shapes range from linear to ovate, with colors from pale to middle green. The blooms come in different shapes as well, ranging from a single row of petals to a doom shape. Their colors range from purple, red, pink, orange, yellow and white to multicolored. There are many different types of this flower. They come in dwarf types, quill-leaf cactus types and spider types. Fully grown Zinnias range from six inches high with a bloom less than an inch in diameter to plants four feet tall with seven-inch blooms. This plant will grow in most soil types, but thrives in humus-rich, well-watered, well-drained soils. They like the direct sun at least six hours a day; however, they will tolerate just the afternoon sun.
If grown as an annual, they can be started early indoors around mid April. Any earlier and they just might grow too large to manage as the plant germinates in only five to seven days. However, these plants are said to dislike being transplanted. If seeding is done outdoors, they should be sown in late May, after the threat of the last frost, when the soil is above sixty degrees. They will reseed themselves each year. Plant the seeds a quarter-inch deep, covered with loose soil. For bushier plants, pinch off an inch from the tips of the main stems while the plant is still young.
If I am fortunate to have you view my photographs and you find the color saturation too much or the color schemes of the mats do not match either themselves or the photograph, please let me know via a comment. Being color-blind, what might look great to me might look like sh*t to everyone else!
