Red Velvet Amaranth Seeds – Amaranthus cruentus – Giant Burgundy Flower Plumes for Dramatic Garden Backdrops & Dried Arrangements.
🌺 The King of the Summer Garden
Red Velvet Amaranth is an imposing, spectacular annual that commands attention. Its thick, upright flower spikes look like columns of deep burgundy velvet, creating a dramatic, architectural presence in the garden. Rising to 5–6 feet tall, it serves as an excellent backdrop for lower-growing flowers or as a centerpiece in large containers. The flowers are incredibly long-lasting, both in the garden and when cut and dried. Heat-loving and low-maintenance, this is one of the most rewarding tall annuals you can grow from seed.

📏Spacing & Seeding Instructions
- Plant Spacing: Space plants 18 to 24 inches apart for full growth and good air circulation.
- Seeding Density (Per Linear Foot): For a border row, sow 4–6 seeds per linear foot and thin later.
- Seeding Density (Per Square Foot): For mass planting, sow 6–8 seeds per square foot.
-
Sowing Depth: ¼ inch (0.6 cm) deep. Cover seeds lightly with soil.

🧑🌾 Step-by-Step Planting Instructions
Start Indoors (Recommended for Zones 3–7):
- Fill seed trays or small pots with moist seed-starting mix.
- Sow seeds ¼ inch deep (cover lightly with soil). Seeds germinate best in darkness.
- Place the tray in a warm area (70–80°F). Keep soil moist but not soggy.
- Seedlings emerge in 7–14 days. Move to a bright location.
- After 4–6 weeks, harden off seedlings over 5–7 days before transplanting outdoors.
Direct Sow (Best for Zones 8–10):
- Wait until soil temperature reaches 65°F (18°C) and all frost danger has passed.
- Prepare a well-drained bed in full sun. Remove weeds and loosen soil.
- Sow seeds ¼ inch deep, spacing seeds 4–6 inches apart in rows.
- Water gently to avoid washing seeds away.
- After 3–4 weeks, thin seedlings to 18–24 inches apart.
Ongoing Care:
- Watering: Water regularly until established (first 4 weeks). Once mature, water once per week during dry periods. The plant is drought-tolerant but produces best with consistent moisture.
- Fertilizing: Apply a balanced, slow-release fertilizer at planting time. Avoid over-fertilizing (can cause excessive leaf growth and fewer flower plumes).
- Support:Tall plants may need staking in windy areas. Use bamboo stakes or tomato cages to keep them upright.
- Deadheading:Not necessary. Spent flowers can be left on the plant for visual interest or harvested for dried arrangements.
- Harvesting (Cut Flowers): Cut flower plumes when they are fully colored but before they begin to fade. Strip lower leaves and place in water immediately.
- Harvesting (Dried Flowers): Cut plumes as above. Hang them upside down in a warm, dry, dark, well-ventilated area for 2–3 weeks. They will hold their color and shape for years.
