Castle Scarlet, also known as Celosia plumosa, Plumed Cockscomb, or Silver Cockscomb, is a cultivar of Celosia argentea, an annual native to Nigeria, Madagascar, and Tanzania. "Celosia," Greek for "burning," lives up to its name with vibrant plumes of color. Takii Seed developed the Castle variety for excellent resistance to heat and drought and beautiful coloring. This plant offers an upright habit 16-20" tall, with long-lasting, red flowers from spring until frost. Any cottage, rustic, or tropical flower garden will benefit from Castle Scarlet's long season of showy color and texture. Bring color and texture to landscape beds, borders, and containers with this low-maintenance plant. Long-lasting as a cut or dried flower, Celosia is an obvious choice for cut-flower gardens. Castle Scarlet flourishes with little more than full sun and regular water. Grow Scarlet alongside Castle Orange and Castle Yellow for a stunning combination.

1. Space plants 10-12" apart in well-drained soil in full sun when temperatures are reliably above 55 degrees.
2. Water once or twice a week or more often in drought, and fertilize monthly with a balanced all-purpose feed according to the label's instructions.
3. Trim back growth slightly during mid-summer to refresh plants. Removing spent flowers can encourage more blooms.
4. Watch for aphids and spider mites.
5. Cut stalks and hang them upside down until dry for use in dried arrangements or wreaths. Dried Celosia will have color for up to six months.
General Growing Tips For Your Seedling Tray
For best results with Castle Scarlet, plant one seedling plug per 1801 cell or 4-inch container or 3-5 per 10-inch container. Use a well-drained soil in full sun with a pH of 6.0-6.6, EC of 10-2.6 mS/cm (PourThru), and light feed (100-150 ppm). Maintain temperatures of 70-75 daytime and 65-68 nighttime. This cultivar is day-neutral. Water regularly, but allow the soil to dry between waterings. This variety responds to A-Rest, Cycocel, B-Nine, Bonzi, and Sumagic as needed and doesn't require pinching. Watch for aphids, spider mites, botrytis, and powdery mildew.
Flowering
Red flowers blooms from spring until frost.
Pinching
This cultivar doesn't require pinching.
Spacing
We recommend spacing containers of Castle Scarlet seedling plugs 6-8" apart in your greenhouse. Provide proper spacing to allow airflow and sunlight to reach around the base and foliage of each plant. Adequate spacing is one of the best preventative measures against diseases, legginess, and stunted growth.
Height Control
In perfect cultural conditions, this cultivar may not need PGRs. However, it responds well to A-Rest, Cycocel, B-Nine, Bonzi, or Sumagic. Use any chemical growth regulator according to the label's instructions.
Pests
You may see aphids and spider mites. Scout regularly for pests and implement an Integrated Pest Management plan in your greenhouse to prevent insects and diseases from damaging your crops.
Aphids are small, soft-bodied insects that cause damage by sucking sap from plant tissue. They reproduce quickly and are particularly attracted to young growth. Curling and yellowed leaves, stunted growth, and stickiness on leaves are signs of an infestation. These insects also spread diseases and reproduce rapidly. Use biological controls or horticultural oils to discourage and kill aphids.
Spider Mites are tiny pests that cause stippling, yellowing, and webbing on foliage by feeding on plant sap. They flourish in warm, dry environments. Use correct water and fertilizing practices; over-fertilizing can attract spider mites. Proper humidity levels, predatory mites or ladybugs, and insecticidal soaps or oils may prevent or address a spider mite infestation.
Discourage pest infestations by sanitizing materials and surfaces, watering appropriately, and keeping the greenhouse clean and free of debris.
Disease
Watch for signs of Botrytis and Powdery Mildew and treat plants preventatively or at the first sign of infection.
Botrytis is a common fungal disease that causes brown spots on stems, leaves, and flowers. Remove and destroy affected plants, maintain appropriate humidity levels, and apply fungicides with boscalid, fenhexamid, or iprodione to control the spread. Water plants in the morning and allow the soil to dry slightly between waterings.
Powdery Mildew is a fungal disease that thrives in humid conditions, appearing as a white or gray coating on foliage and flowers. Provide good airflow in your greenhouse. We recommend horizontal airflow fans to help control humidity levels alongside a dehumidifier or manual venting. Remove and destroy infected plants and apply fungicides as needed or preventatively. Look for the active ingredients myclobutanil, trifloxystrobin, or potassium bicarbonate to combat Powdery Mildew threatening your seedling plugs.
Planting Castle Scarlet Liners
We recommend planting one seedling plug per 1801 cell or 4-inch container or three to five per 10-inch container. Use well-drained soil and completely bury the ellepot centered or evenly spaced in the container. Water each seedling after transplanting.
Rooted Cuttings
Cuttings vary in size between different plant families. These rooted starter plants will arrive ready to be transplanted in to your final container. If they are to be used in a landscape application, you will need to establish them in a 4 inch pot or an 1801 before planting outside.

Before we take this relationship any further...
It looks like this is the first time you've added anything to your cart.
We just wanted to remind you that we are a wholesale starter plant company that sells to businesses, schools, clubs, and other non-profits. State law dictates that you must be growing for resale to order from us since we are not collecting sales tax.
If we aren't a match, we understand. It's not you, it's us.
We would look awful in orange jumpsuits.
