Is celosia annual or perennial?

The answer depends on the species of celosia and the climate in which it is grown. In general, celosia is considered to be a tender perennial. This means that it can survive for several years in warm climates, but it will not survive the winter in cold temperatures. Some species of celosia can live for up to three years. Also, depending on the species and the growing conditions, 

So, Celosia can be either an annual or perennial plant. Celosia can not survive if the temperatures fall below 30 degrees Fahrenheit. It does not tolerate cold well. Celosia is generally grown as annuals in zones 2-9 and as perennials in zones 10 and 11.

Annual Celosia: Many varieties of celosia are grown as annuals. These annual celosia plants are typically treated as decorative bedding plants, adding vibrant color and unique textures to gardens and containers during the summer months. They are not expected to survive winter frosts and cold temperatures.

Perennial Celosia: Some celosia species, such as Celosia argentea, have perennial tendencies in regions with mild climates and frost-free conditions. In these areas, perennial celosia plants can survive and regrow year after year. However, it’s important to note that even perennial celosia plants may experience diminished vigor or die back in winter or during unfavorable conditions.
