Main Types of Celosia
Celosia is primarily categorized into three types: Celosia argentea var. cristata, known for its brain-like, crested flowers; Celosia argentea var. plumosa, featuring feathery, plume-like blooms; and Celosia argentea var. spicata, distinguished by its spike-like flowers. Each type offers a unique aesthetic, with a spectrum of colors from fiery reds and oranges to soft yellows and pinks, making them versatile for various garden designs.
When to Plant Celosia
This succulent prefers a sandy, well-draining soil to prevent root rot. A commercial cactus or succulent mix is ideal, but you can make your own by mixing 2 parts standard potting soil, 2 parts coarse sand, and 1 part perlite or pumice. This fast-draining medium will support root health, an essential factor for succulents’ survival. It’s crucial to avoid soil types that retain moisture, like clay, as these can cause the roots to remain wet and promote fungal diseases.
Where Celosia Thrives Best
Aeonium ‘Voodoo’ does best in warmer temperatures and doesn’t fare well in freezing conditions. It thrives in temperatures between 65 – 75°F (18 – 24°C) and requires protection from frost. If you live in a zone with colder winters, consider growing it in a container that you can move indoors during freezes. While this plant prefers a drier climate and high humidity levels can lead to rot, it can tolerate coastal areas’ moisture. During heatwaves, providing shade can help prevent the leaves from getting sunburnt.

- Sow the Seeds: Plant Celosia seeds shallowly, about 1/8 inch deep. Space the seeds or seedlings about 8 to 10 inches apart.
- Water Gently: Water the seeds gently but thoroughly. Keep the soil consistently moist until germination, which usually occurs within 1-2 weeks.
- Provide Care: Once the seedlings emerge, reduce watering but ensure the plants receive enough moisture, especially during dry spells.
- Mulching: Apply a layer of mulch around the plants to retain moisture and control weeds.
- Fertilize: Feed the plants with a balanced fertilizer every 4-6 weeks to encourage robust growth.
- Deadheading: Remove spent flowers to encourage more blooms and extend the flowering period.
- Watch for Pests and Diseases: Keep an eye out for common pests like aphids and fungal diseases. Treat promptly if needed.
