African vs. French vs. Triploid: Which Marigold Type Is Right for Your Program?
Before selecting a series, it helps to understand the three main marigold types grown commercially:
| Type | Plant Height | Bloom Size | Best Use | Days to Bloom |
|---|---|---|---|---|
| African (T. erecta) | 18–36" | 3–5" double | Bedding, landscape, dried, some cut | 55–75 |
| French (T. patula) | 8–14" | 1–2" single/double | Bedding, borders, companion planting | 45–55 |
| Triploid (T. ×hybrida) | 10–16" | 2–3" double | Landscape, mass planting, heat tolerance | 50–60 |
Best African Marigold Seeds for Bedding & Landscape Programs
African marigolds dominate commercial bedding and landscape programs because of their large, uniform blooms, strong stems, and heat tolerance. These are your workhorses for high-volume production.
Taishan® Series – The Industry Standard for Uniform Bedding Production
The Taishan® Yellow and Taishan® Gold are the benchmark for commercial bedding programs. Compact, early-flowering, and extremely uniform — ideal for 4" and 6" pot programs. Blooms in 55–60 days from transplant. Available in Yellow, Orange, Gold, and Mix.
Marvel II™ Series – Tall, Bold Blooms for Landscape Impact
The Marvel II™ Yellow and Marvel II™ Gold produce large 4–5" blooms on tall, sturdy plants — perfect for landscape borders, mass plantings, and high-visibility commercial installs. Strong heat and humidity tolerance.
Proud Mari Series – Mid-Height Versatility
The Proud Mari Gold sits between compact bedding and tall landscape types — a great all-rounder for growers who need one variety to serve multiple accounts. Available in Gold, Yellow, Orange, and Mix.
Best Marigold Seeds for Cut Flower Programs
Most marigold varieties are not bred for cut flower production — stem length, vase life, and petal density matter here. These two African series are the exceptions worth growing for florist and farmers market programs.
Coco Series – Premier Cut Flower African Marigold
The Coco Gold and Coco Yellow are specifically bred for cut flower production — long stems (24–30"), dense double blooms, and excellent vase life. A top choice for florists and flower farmers who want marigolds that actually perform in the vase.
Nosento Limegreen – Unique Color for Specialty Markets
The Nosento Limegreen is a standout specialty cut flower variety with unusual lime-green blooms that command premium prices at farmers markets and with florists. Excellent stem length and a conversation-starter in any mixed bouquet.
Best Marigold Seeds for Dried Flower Programs
African marigolds dry exceptionally well — their dense petals hold color and shape through the drying process. The Taishan and Marvel II series are both strong performers for dried programs, but any large-headed African variety works well when harvested at peak bloom and hung to dry.

Best French Marigold Seeds for Bedding & Border Programs
French marigolds are the go-to for compact bedding programs, 4-packs, and border plantings. They flower faster, tolerate cooler conditions better than African types, and are a staple for spring bedding plant sales.
Top series for commercial production include the Super Hero series (uniform, early, excellent shelf life), the Disco series (bicolor options, strong branching), and the Chica series (compact, early, great for 4-packs). Browse all French marigold varieties at trailingpetuniabulkseeds.com.
Triploid Marigolds – Zenith Series for Heat-Tolerant Landscape Programs
Triploid marigolds like the Zenith series are sterile hybrids that bloom continuously without deadheading — a major advantage for landscape maintenance accounts. They tolerate summer heat better than French types and produce larger blooms than standard French varieties. Available in Yellow, Orange, Red, and Mix.

Frequently Asked Questions
What are the best marigold seeds for commercial bedding plant production?
The Taishan® series is the industry standard for commercial bedding programs — compact, uniform, early-flowering, and available in 1,000-seed quantities. Antigua and Inca II are also strong choices for 4" and 6" pot programs.
Which marigold varieties have the longest stems for cut flower use?
The Coco series (Gold and Yellow) and Nosento Limegreen are the top African marigold varieties bred specifically for cut flower production, with stems reaching 24–30" and excellent vase life. Most other marigold varieties are not suitable for cut flower programs.
What is the difference between African and French marigolds for growers?
African marigolds (T. erecta) grow taller (18–36"), produce larger blooms (3–5"), and are better suited for landscape, dried flower, and cut flower programs. French marigolds (T. patula) are compact (8–14"), flower faster, and are the standard for bedding plant 4-packs and border programs.
How many marigold seeds do I need per acre for a commercial planting?
For transplanted programs, plan on 4,000–6,000 plants per acre depending on spacing (12–18" centers). At typical germination rates of 85–90%, a 1,000-seed packet will produce approximately 850–900 transplants. For large-scale production, contact us for bulk pricing.
Can I direct sow marigold seeds for commercial production?
Yes — marigolds germinate readily from direct sow in warm soil (65°F+). However, most commercial growers start in plug trays for uniformity and earlier bloom timing. Direct sow works well for succession plantings later in the season.
What marigold varieties are best for dried flower programs?
Large-headed African varieties like Marvel II™, Taishan®, and Proud Mari dry exceptionally well. Harvest at peak bloom, remove foliage, and hang upside down in a warm, dry location with good airflow. See our full Dried Flower Program guide for detailed protocols.
Do you sell marigold seeds in bulk quantities for commercial growers?
Yes — all marigold varieties at trailingpetuniabulkseeds.com are sold in 1,000-seed quantities, sized for commercial plug tray and bedding plant production. Browse the full catalog and contact us for volume pricing on larger orders.
