Celosia is a colorful annual flower known for its flame-shaped plumes and unique cockscomb blooms. Locally grown at Holub Greenhouses, celosia thrives in Iowa’s summer heat and adds long-lasting color and texture to sunny flower beds, borders, containers, and bouquets.
Is Celosia an annual?
Celosia is typically grown as an annual in Iowa because it does not tolerate frost. These heat-loving flowers thrive during the summer and continue adding vibrant color to gardens and containers until cold weather arrives.
In warmer climates, some types of celosia may grow as tender perennials. Central Iowa gardeners, however, should plan to grow celosia as an annual and replant it each year.
why choose celosia for your Iowa garden?
Celosia (Celosia argentea) flowers bring bold color and unique texture to sunny Iowa gardens. Available in vibrant shades of red, orange, yellow, pink, and magenta, these heat-loving annual flowers perform well throughout Central Iowa’s warm summers.
Upright plume varieties add height to flower beds and containers, while crested cockscomb varieties are known for their distinctive, coral-like blooms. Celosia also makes an excellent cut flower, giving gardeners another way to enjoy its colorful blooms throughout the season.
When should I plant Celosia in Iowa?
