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.
Grow celosia in full sun - at least 6 to 8 hours a day. Well-drained, nutrient-rich soil keeps plants growing strong. Use a liquid plant food every couple of weeks, especially if it's been rainy or really hot: Lots of rain can wash away nutrients and temperatures above 95 degrees F slow growth.
Celosia flowers are in the Amaranthaceae family and are basically of two groups. The variety shown here is the plumosa group. It's the more popular of the two, often grown in flower beds, containers, and indoors as house plants.. . . . .364011236364!]0000000000000009783314145757!]
