How to Grow

For the best results with Celosia argentea (Cristata Group) ‘Tornado Red’, ensure planting occurs only after all danger of spring frost has passed. If starting seeds indoors, begin 6-8 weeks prior to your last expected frost date for an earlier start. Otherwise, seed may be sown directly into the garden soil after the danger of frost has passed. Seedlings or purchased plants should be transplanted carefully into their final locations once settled weather arrives.

These plants prefer humusy, moderately fertile, and consistently moist soil, though they are quite tolerant. While they appreciate consistent moisture, well-drained soil is crucial to prevent root rot, a primary concern for this species. Cockscomb thrives in full sun but can tolerate light shade, although flowering may be reduced.

Watering should be done regularly to maintain medium moisture levels, especially during establishment. Taller cultivars, like ‘Tornado Red’ reaching 2 feet, benefit from being placed in spots sheltered from strong winds to prevent stem damage. Deadheading spent flowers is recommended to encourage prolonged bloom production throughout the summer season.

Landscape Uses

The vibrant magenta of Celosia argentea (Cristata Group) ‘Tornado Red’ makes it incredibly effective when massed in beds or used as a component in mixed borders, providing strong vertical accents. Because they offer such intense, lasting color, they are highly valued in cutting gardens for both fresh presentation and for drying. Their upright nature makes them suitable for edging where you need height without excessive spread.

These showy annuals integrate well into hot, sunny locations where many other plants might struggle by mid-summer. Consider grouping them with fine-textured foliage plants or silver-leafed companions to contrast their coarse, crested blooms. Their relatively compact size (1.5 to 2 feet tall) also makes Celosia argentea (Cristata Group) ‘Tornado Red’ an excellent choice for large containers as a feature plant.
