The "Lilliput" mix created another Zinnia sensation when it was introduced. The semi-dwarfed plants (only 18 to 24" tall) are famous for forming bushy 12" wide growth with lots of flowers, and the pom pom blooms are in clear solid colors. The sizzling, colorful effect in the garden is stunning, making these perfect for edging or colorful patches anywhere you want bright color. Just plant the seeds, and remember to cut off the fading flowers.
Easy! Easy! Why everybody loves Zinnias: Probably no plant can give you more color for less work. It's because the zinnia is one of the easiest plants to grow from seed (any child can do it, and many do!), they'll give you every color but blue, and they bloom all season up until frost. Can you think of another flower that does all that?
How to grow them: Good full sun is really all that's required, although some of the newer hybrids will even bloom in partial shade. As for water, they don't need much, since they're from hot desert-like habitats. Soil? Almost any soil will do, but they prefer fast-draining gritty soil, if you have that available.
Zinnia seeds are perfect for starting indoors to have bloom early. But be sure you wait until every frost is gone, and the soil has warmed up a bit before setting them out. They're super-sensitive to frost--after all, these plants are from frost-free regions, and don't like cold soil. If you'd rather, you can just wait until spring arrives, and sow them outside. They're very undemanding.
The Wildflower that's been all dressed up for years. There about 20 species of Zinnia in the wild, all in the arid, rocky soils of North, Central and South America, most common in Mexico. If you saw the wild plants, you'd be amazed, since Zinnias are one of our most heavily-hybridized wildflowers, and the somewhat "ragged" originals look nothing like our garden beauties. That's because hybridizers discovered them early, and have been "working on them" for decades.
The Wild Ones The most commonly hybridized species is Zinnia elegans, a common wild plant in Mexico. But in recent years, work has been done on some of the other species. Like the dahlia (also from Mexico) the Zinnia takes quickly and willingly to almost anything the hybridizers want to do: Taller, shorter, or bigger flowers. Multi-colored flowers. You name it, and they seem to be able to do it to Zinnias.
Because of that, these flowers have been staples among major color-makers in gardens since your great-grandmother's time, and more and more beautiful zinnias are created for our gardens almost every year.
