Do Celosia Plants Come Back Every Year? Celosia is considered a tender perennial in zones 9 and 10, or a hardy annual otherwise. In warmer climate areas, you can get it to grow back year after year. In most climates, though, they will need to be replanted each year.
Celosia spicata (= C. argentea var. spicata) is a summer annual or short-lived perennial (zones 9-11) grown as an ornamental for its distinctive, erect flower spikes sort of reminiscent of a sheaf of wheat that give it the common name of wheat celosia.
Celosias are one of the most eye-catching annuals to grow in the garden. Technically speaking, however, they are tender annuals, as they are perennial in Zones 10 to 12.
What do you do with celosia in the winter?
It is possible to overwinter them but keeping the soil just moist not wet and in temperatures around 70 degrees or warmer can be hard in the winter months. Also make sure they are planted in a potting mix that is well draining. If the pot is sitting in a tray be sure to keep the tray emptied of any draining water.
Does celosia reseed itself?
Celosia is easily dried by hanging small bundles of flower stems upside down in a cool, dry room with good ventilation. The seeds will fall out as they dry. These plants will self-seed readily and although the seedlings are easy to remove, it can become a weed as they set seed prolifically.

How to grow celosia. Celosia seeds can be sown indoors in a warm environment in early spring, ideally in a propagator at a temperature of between 20-25ºC (68-77ºF). The seeds should germinate in 1-2 weeks, and the seedlings can either be planted outside in summer or grown as indoor plants.
How cold can celosia get?
Grow in a disease-free, well-drained media with a pH of 5.5-6.0. Grow on at 60-65° F. Celosia is a heat-loving plant and does not tolerate cool temperatures during the growing stage. Low temperatures can cause premature flowering and can result in poor garden performance.
How far apart should celosia be planted?
Celosia perform best in garden beds and will often be stunted if grown in containers. They can be planted outdoors once soil temperatures are above 55 degrees Fahrenheit. Plants should be spaced about 8-12 inches apart depending on cultivar.
