Zinnia elegans are a commonly grown garden annual. These plants are usually just referred to as Zinnias.
Zinnias carry colorful flowers and are native to Mexico, but are commonly found throughout the Americas.

These plants are great to grow if you wish to bring a variety of bright colors to the garden.
They are also great to grow if you wish to attract helpful garden pollinators such as butterflies and hummingbirds.

They're relatively easy to grow annuals, producing showy blooms from June until the first frost of the year.
For best results, start sowing seeds immediately after the last frost date. Continue sowing zinnia seeds out every 2-3 weeks through to the end of June; this will almost guarantee that there will be blooms throughout the entirety of the season.
These somewhat large flowering plants need to be planted at least 18 inches apart (45 cm) as they can up to 4 feet tall (1.2 m) and one foot (30 cm) wide.
Zinnias grow well in USDA zones 2 through 11 (UK zone H2). They do need a decent amount of water to produce nice flowers, as the blooms are somewhat large.
Depending on the zinnia variety used, blooms can be pink, red, purple, yellow, white, orange, or green.
Zinnias grow well in various soils including clay, loam, chalk, and sand. The soil pH is not overly important. But do ensure that the soil drains well, but remains moist.
Zinnia elegans plants require a decent amount of attention but are still a somewhat hardy flower. This means that they can easily be grown by gardeners with little experience yet remain beloved by experienced gardeners as well.
