Amaranth flower seeds deliver towering plumes of burgundy, gold, and crimson that transform a flat bed into a vertical spectacle. This ancient grain and ornamental dual-purpose crop shrugs off heat, resists pests, and asks for nothing more than full sun and decent drainage.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. I spend my time comparing seed genetics, evaluating germination data from diverse zones, and cross-referencing hundreds of verified buyer reports to separate the truly vigorous from the merely advertised.
This guide breaks down the five strongest players on the market today. After weeks of reviewing cold stats and real-world outcomes, I’ve narrowed the field to three distinct picks that fit different goals. Whether you want microgreens, grain harvests, or cut flowers, the right best amaranth flower seeds turn ambition into a reliable seasonal payoff.
How To Choose The Best Amaranth Flower Seeds
Amaranth seed selection isn’t complicated, but picking the wrong packet can mean undersized plants or a color that clashes with your garden plan. Focus on three factors before you click “buy.”
Seed Count vs. Seed Weight
A packet labeled “600 seeds” from a premium brand uses a different volume than a bulk bag sold by the pound. For a home flower border, a three-to-four-packet collection gives you variety without forcing you to plant an entire row of the same color. For microgreen growers, a full-pound bag like the Red Garnet option makes economic sense because you sow densely and harvest quickly.
Growth Height and Bloom Color
Amaranth plumes range from 2-foot dwarfs to 6-foot giants. Chinese Giant Orange produces golden heads that tower well above eye level, while Hopi Red Dye stays more compact with deep burgundy tassels. Check the expected plant height on the packet — a 4-foot variety placed behind low-growers creates depth; a 6-foot monster in a shallow raised bed can topple in wind.
Intended Use: Ornamental, Grain, or Microgreen
Not all amaranth is bred for the same purpose. Grain varieties need a long, dry fall to mature seeds. Ornamental types prioritize dramatic flower heads. Microgreen amaranth is harvested at the cotyledon stage for color and tender texture. If you buy a grain-focused packet and try to harvest microgreens, the stems can be tougher and less palatable.

In‑Depth Reviews
1. Plant Good Seed Organic Amaranth Seed Variety Pack
This four-packet collection covers the amaranth spectrum: Chinese Giant Orange (for towering golden plumes), Elephant Head (for dense, knobby blooms), Hopi Red Dye (for deep burgundy tassels and natural pigment), and Red Callaloo (for edible leaves). Each packet holds exactly 600 seeds, and the seeds are certified organic, non-GMO, heirloom, and open-pollinated. That certification alone matters if you plan to harvest the leaves for salads or cook the grain — no synthetic treatments lingering in the soil.
Real-world germination reports are strong. Growers in ground report plants hitting 6 feet plus within three months, with huge golden-orange heads that produce coffee-can volumes of seed. One verified buyer noted the plants “grew well over my head” and required zero supplemental water once they passed 1 foot tall. Indoor hydroponic users also confirm success: the seeds sprout reliably in Aerogarden units and produce harvest-ready greens every 2-3 weeks.
The only catch is that amaranth self-seeds aggressively. If you let the flower heads shatter, you’ll have volunteers everywhere next season. That’s fine for a cottage garden, but a problem for strictly manicured beds. On the plus side, drought tolerance and pest resistance are baked into the genetics — one reviewer mentioned iguanas eating the leaves but bugs leaving the stems alone.
What works
- Certified organic and open-pollinated, ideal for seed saving
- Four distinct varieties cover grain, dye, edible leaf, and ornamental uses
- Outstanding drought tolerance once established
- High germination rate reported across ground, raised beds, and hydroponics
What doesn’t
- Performs poorly in containers — needs in-ground or large raised beds
- Self-seeds aggressively if flower heads are not cut before shattering
- Higher per-packet cost compared to bulk mixes
2. Open Seed Vault 15,000 Heirloom Seeds
This vault packs 32 vegetable varieties (bean, beet, bell pepper, broccoli, Brussels sprout, cabbage, cantaloupe, carrot, cauliflower, celery, corn, cucumber, eggplant, kale, three lettuce types, lima bean, okra, onion, pea, parsnip, pumpkin, radish, spinach, sunflower, Swiss chard, tomato, turnip, watermelon, zucchini) into one resealable mylar pouch. The total seed count is 15,000 — enough to cover a quarter-acre garden multiple times. Each variety is individually packed in a waterproof resealable packet with a full growing guide included.
Customer feedback emphasizes viability over flash. One first-year gardener planted on unprepared beds and reported “excellent germination” even after seeds overwintered in the soil. Another reviewer in zone 7 got a 100% sprout rate across every packet. The kale and mustard family seeds are particularly vigorous — they survived cold weather and produced crops via the “STUN” (sheer total utter neglect) method. The resealable mylar packaging is a practical bonus for long-term storage, with a reported 25+ year shelf life under proper conditions.
The trade-off is that this is a vegetable mix, not an ornamental amaranth collection. If you want showy red plumes for cut flower arrangements, you won’t find them here. But for anyone building a self-sufficient garden where amaranth grain is part of the bigger food picture, this vault gives you the companion crops to rotate alongside your amaranth beds. The variety list leans heavily toward staples — no microgreen-specific genetics or high-dye varieties.
What works
- Mylar resealable packets with long-term storage potential
- Proven high germination rate across many zones
- Massive seed count — cost per seed is negligible
- Includes a guidebook for beginner gardeners
What doesn’t
- No amaranth-specific or ornamental flower varieties included
- Some packets contain very few seeds (e.g., sunflower)
- Corn and squash late planting may underperform in short seasons
3. Survival Garden Seeds Medicinal Herb Collection
This 18-variety kit targets the herbal tea and tincture crowd: English Lavender, Roman Chamomile, Purple Coneflower (Echinacea), Peppermint, Spearmint, Common Sage, White Sage, Lemon Balm, White Yarrow, Catnip, Marigold, Oregano, Holy Basil Tulsi, Bergamot, Borage, Fennel, Fenugreek, and Lovage. While none of these are amaranth, the collection matters to amaranth growers because it fills the companion-plant role perfectly — the marigolds and borage attract pollinators that boost amaranth seed set.
Germination feedback is solid. Marigolds are the standout performers: one reviewer reported two plants hitting 4.5 feet with dozens of orange and yellow blooms that attracted butterflies despite leaf miner damage. Lemon Balm and Catnip sprouted reliably even in a cool summer, and Roman Chamomile showed a high germination rate. The packaging is practical — each variety comes in a labeled packet with basic growing instructions, and the set is housed in a resealable bag for moisture protection.
The weak spots are the slow-starting perennials. Echinacea is notoriously slow from seed (some users reported barely any visible growth in the first month), and White Sage can be finicky in humid climates. Cold-climate growers also noted that marigolds struggled to flower before frost in zone 5 and below. If you’re looking specifically for amaranth genetics, this isn’t it — but as a companion to a dedicated amaranth bed, the pollination and fragrance benefits are real.
What works
- Broad variety of culinary and medicinal herbs in one purchase
- High germination on fast-growing species like marigold and chamomile
- Companion planting benefits for amaranth beds
- All heirloom and non-GMO — suitable for seed saving
What doesn’t
- No amaranth seeds included — entirely herb-focused
- Echinacea and sage have very slow initial growth
- Cold-climate performance is mixed for tender annuals
4. Gardeners Basics 35-Flower Seed Pack
This 35-variety flower collection mixes annuals, perennials, and wildflowers: marigolds, hollyhocks, daisies, pansies, coleus, sunflowers, cosmos, phlox, and more. Each variety is packed in its own labeled seed packet — no plastic bags — and the entire set comes in a giftable drawstring bag. USDA zones 3-11 are covered, making it one of the most geographically flexible options on the list. Best of all, there are no duplicate flowers in the assortment.
Real-world results in zone 5a confirm that direct sowing works. One grower reported that every variety germinated, and the cost per packet was roughly half what you’d pay buying individually. Favorites like Zinnia and Calendula produced “spectacular” cut flower arrangements from summer through fall. The seeds are non-GMO and heirloom, so you can save seed from the strongest performers. A reviewer in zone 3 noted that using coco coir pods accelerated sprouting compared to direct soil sowing.
The packets lack two pieces of information that experienced gardeners want: plant height and sun/shade requirements. When you’re planning a border, not knowing that a certain variety hits 4 feet forces you to look up each species separately. Also, with 35 varieties, some will inevitably underperform in your microclimate — that’s the nature of broad collections. But for sheer variety per dollar, this pack is tough to beat if you want to surround your amaranth plumes with complementary blooms.
What works
- 35 unique varieties with no duplicates — excellent diversity
- Cost per packet is well below individual retail pricing
- Works across a wide USDA zone range (3-11)
- Non-GMO and heirloom, suitable for seed saving
What doesn’t
- Packets lack height and sun/shade instructions
- Not all 35 varieties will thrive in every climate
- Not specifically amaranth-focused — a general flower mix
5. Mountain Valley Red Garnet Amaranth Microgreens Seeds
This 1-pound bag of Red Garnet Amaranth is engineered specifically for microgreen production. The seeds are raw, untreated, and packed in a resealable bag for repeated use. The guaranteed high germination rate (confirmed by multiple buyers) and the vivid red-violet coloration at the cotyledon stage make it a standout choice for indoor growers who want visual contrast in their microgreen mixes. Days to full maturity for the grain stage is 100 days, but microgreen harvests happen in 10-14 days.
Customer feedback confirms that the seeds sprout readily under standard microgreen protocols — a 4-day blackout period followed by light exposure. One grower with experience in sunflower and pea microgreens noted that amaranth requires “more finesse” than those forgiving crops, but the color payoff is superior to beet microgreens as a replacement. Another first-time microgreen grower reported zero mold or fungus issues and called the emerging greens “beautiful.” The “pink greens” from the red stems add a unique aesthetic to any salad mix.
The main criticism is color consistency. One verified buyer received seeds that grew predominantly green with only a few red-tinged sprouts, raising the question of variety accuracy. Because amaranth microgreens are harvested at the stem-and-leaf stage before the true red pigment fully develops, some batches may look greener than expected depending on light intensity and temperature during germination. Also, this bag is bulky — 1 pound of amaranth seed is a lot for a hobby grower; a smaller trial packet would be more practical for first-timers.
What works
- Excellent germination rate with proper technique
- Vivid red-violet stems add unique color to microgreen mixes
- Resealable bag for long-term storage
- Clean seeds — no mold or fungus issues reported
What doesn’t
- Color can vary — some batches produce mostly green sprouts
- 1-pound bag is excessive for casual microgreen hobbyists
- Requires more care than beginner-friendly sunflower or pea seeds
Hardware & Specs Guide
Understanding the small-print details on seed packets separates a strong purchase from a disappointment. Three specs matter most for amaranth flower seeds: seed count vs. weight, variety types, and planting compatibility.
Seed Count Per Packet
A reputable amaranth packet lists a verified seed count, not just a vague “bulk” claim. The Plant Good Seed collection states exactly 600 seeds per packet — enough for a 20-foot row at standard spacing. A bulk bag like the Red Garnet microgreen option uses weight (1 lb) because microgreen sowing is dense: roughly 1-2 ounces per 10×20 tray. For ornamental borders, 600-1200 seeds per variety is the sweet spot; anything less than 200 seeds feels stingy.
Organic & Non-GMO Certification
If you plan to eat the leaves or save the grain, organic certification matters because it guarantees no synthetic pesticides, fungicides, or fertilizers were used on the parent plants. Heirloom and open-pollinated tags are equally important — they mean the seeds will breed true-to-type for next season. The Plant Good Seed collection carries all three marks. The bulk Mountain Valley bag is untreated but not certified organic, so it’s fine for microgreens if you rinse thoroughly before consumption.
