Cleome hassleriana, often called the spider flower, delivers architectural spikes of pink, white, or purple blooms that rise above your garden with an airy, exotic silhouette. The challenge isn’t finding seeds—it’s finding a batch with high germination rates and true-to-type genetics that won’t leave you with a patch of leggy, unimpressive plants.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. I spend my time comparing seed germination data, studying regional hardiness zones, and analyzing aggregated owner feedback to separate reliable genetics from disappointing filler.
Whether you need a single packet for a border or a bulk mix for a meadow, this guide highlights the top-performing options so you can confidently choose the best cleome hassleriana seeds for your specific growing conditions and garden scale.
How To Choose The Best Cleome Hassleriana Seeds
Cleome hassleriana is a vigorous annual that can reach 3-5 feet tall, but not all seed packets deliver the same genetic vigor. Focus on these three factors to ensure a towering, colorful display rather than a sparse patch of stunted plants.
Germination Rate & Seed Freshness
The single most important spec is the germination guarantee. Look for brands that test their seeds and claim rates above 90%. Seeds stored in heat or humidity lose viability fast. Packets sealed in waterproof, resealable pouches preserve freshness for up to three years, giving you flexibility for staggered spring and fall plantings.
Variety & Bloom Color
Cleome comes in shades of white, pink, rose, and purple. Some mixes include only the classic ‘Queen’ series (Cherry Queen, White Queen, Purple Queen), while others blend them with complementary annuals like Cosmos or Snapdragon for a layered look. If you want a uniform hedge of pure spider flowers, buy single-variety packets. If you want a cottage-garden jumble, go for a curated mix.
Packet Size & Coverage Area
For a small border, a standard packet with 50-100 seeds is plenty. Larger landscapes or meadow plantings demand bulk options—some mixes contain 100,000 or even 480,000 seeds, covering up to 1,200 square feet. Match seed count to your planting area. Overspending on massive bulk bags for a tiny bed is wasteful; buying tiny packets for a large plot is frustrating.

In‑Depth Reviews
1. Eden Brothers Vintage Lace Flower Mixed Seeds
This bulk mix from Eden Brothers is the definitive solution for large-scale Cleome displays. It includes Cleome White Queen and Cleome Purple alongside Cosmos Gloria, Bishop’s Flower, Snapdragon Purple, and Purpletop Vervain, giving you a layered, pollinator-heavy cottage garden from a single bag. With up to 480,000 seeds and a coverage area of around 1,200 square feet, this is proper meadow investment, not a trial packet.
Customer feedback highlights remarkably fast germination—sprouts visible in around five days when scattered on soil and kept moist—and vigorous growth that produces flower buds by early May. The blend is suitable for zones 3 through 10, needs full sun, and is labeled 100% non-GMO with no filler species. Buyers consistently note that butterflies, bees, and hummingbirds flock to established patches.
The main compromise is that a few customers found Devil’s Beggarticks (a sticky-seeded weed) mixed in, though this appears inconsistent between batches. The seed count also means you must prepare a large enough area—this is not for a balcony pot. For anyone planning a substantial cleome-studded cutting garden or pollinator strip, this mix delivers the highest seed-to-value ratio on this list.
What works
- Massive 480,000+ seed count covers large areas
- Includes two pure Cleome varieties plus pollinator companions
- Excellent germination speed reported in as little as 5 days
What doesn’t
- Some batches may contain weed seed contamination
- Overkill for small gardens or container beds
2. Eden Brothers Cleome Seeds – Cherry Queen
If you want a specific, named cultivar rather than a random mix, Cherry Queen from Eden Brothers is the authentic heirloom single-variety option. Its brilliant red blooms form tight, upward-facing flower clusters atop stems that can reach 3-4 feet, making it ideal for creating a uniform back-of-border hedge. The seeds are harvested from true-to-type stock, so you won’t get drift into pink or white shades.
This variety requires cold stratification before planting to break dormancy—a quick chill in the fridge for several weeks mimics winter conditions. The payoff is a long bloom window from midsummer through early fall. Customer reviews confirm strong germination and hardy seedlings, with several praising the plant’s vigor even in less-than-ideal soil conditions.
The packet size is modest, making it suitable for targeted plantings of 10-20 plants in a standard bed. It does not come with stratification instructions printed on the packet, so first-time cleome growers need to research the pre-treatment step. For gardeners who insist on red spider flowers and want genetic purity, Cherry Queen is the standout choice.
What works
- True-to-type heirloom red Cleome with no color mixing
- Strong germination reports from verified buyers
- Attracts pollinators throughout summer and fall
What doesn’t
- Cold stratification is mandatory for good results
- Single variety limits visual diversity in one packet
3. Organo Republic 16 Perennial Wildflower Seeds Mix
Organo Republic’s perennial wildflower mix is a bulk option built for longevity—16 species including Purple Coneflower, Shasta Daisy, Lupine, and Black-Eyed Susan, all selected to return year after year in zones 3 through 9. While Cleome hassleriana itself is an annual, this mix provides the backdrop structure that makes spider flowers pop when planted alongside it.
The germination rate is reported by customers to be fast, with sprouts appearing within a week and steady growth throughout the season. The resealable waterproof pouch protects viability for up to three years, and the QR-code growing guide simplifies planting for novices. The seed count—over 100,000—allows broad coverage without requiring you to buy another bag next season.
Because this mix is perennial-focused, it does not contain Cleome itself. You would need to supplement with a pure Cleome packet if spider flowers are your primary goal. The value here is for the gardener who wants a perennial foundation that complements Cleome’s annual growth, reducing annual replanting labor across the rest of the bed.
What works
- Perennial mix returns yearly, reducing replanting work
- High germination and fast sprouting verified by users
- Resealable packaging preserves seed viability long-term
What doesn’t
- Does not include Cleome—must buy separately
- 16 varieties can feel chaotic in formal garden designs
4. Seedphony 16 Perennial Wildflower Mix
Seedphony’s 16-variety perennial wildflower mix is a strong mid-range option for gardeners who want high germination guarantees without paying premium-tier prices. The brand claims a germination rate above 90%, and customer feedback backs this up—multiple reviews note sprouts appearing in 2-3 days with vigorous early growth. It includes popular annuals like Cosmos, Zinnias, Marigolds, and Sunflowers alongside perennials, giving fast first-year color.
The waterproof, resealable pouch is a practical advantage: seeds stay dry and viable even if stored in a damp garage or shed. The QR-code guide walks beginners through soil prep, watering schedules, and sun requirements. Sourced and packaged in the USA, the mix includes pollinator-attracting species that pair well with Cleome for a bee- and butterfly-friendly garden.
Like the Organo Republic perennial mix, this does not contain Cleome seeds, so it works best as a companion blend. Some customers mention that soil preparation and patience are still required—seeds scattered on bare clay without prep will struggle. For budget-conscious gardeners building a mixed pollinator bed, this offers the best germination confidence at this price level.
What works
- Advertised >90% germination rate backed by user reports
- Waterproof packaging protects seeds during storage
- Includes fast-blooming annuals for same-season color
What doesn’t
- No Cleome included—must purchase separately
- Results are highly dependent on soil prep quality
5. Organo Republic 15 Edible Flower Seeds Variety Pack
Organo Republic’s edible flower variety pack takes a different angle—15 non-GMO heirloom species such as Borage, Calendula, Echinacea, Lavender, and Zinnia, all selected for both visual appeal and culinary use. At roughly 4,800 total seeds, it’s a low-count, high-diversity option ideal for small urban gardens, container patios, or new gardeners who want to sample multiple flowers without committing to one massive bag.
The resealable packets each carry a QR code linking to specific growing instructions, and the seeds are tested for germination before packaging. Customer reviews emphasize high sprouting success and the joy of eating the blooms—the included cooking guide adds a lifestyle element that pure ornamental seed packs lack. The mix works well for both indoor windowsill germination and direct outdoor sowing.
Crucially, this pack does not contain Cleome hassleriana, so it is useful only as a companion or starter mix. The small seed count means it will not fill a large bed—it’s best treated as a sampler or gift box. For anyone seeking a true cleome-dominant planting, this is not the right primary purchase, but as a complementary edible garden add-on, it earns its place.
What works
- 15 culinary varieties with cooking guide included
- High germination rate confirmed by multiple 5-star reviews
- Resealable packets with QR-code instructions
What doesn’t
- Does not include Cleome hassleriana
- 4,800 seeds are low volume for large-scale planting
Hardware & Specs Guide
Germination Rate & Stratification
Cleome seeds require consistent moisture and warm soil (70-75°F) to germinate. Some cultivars, like Cherry Queen, benefit from cold stratification—place seeds in a damp paper towel inside a sealed bag in the refrigerator for 2-4 weeks before sowing. Always check the packet instructions; many blends skip this step by including only stratification-independent varieties.
Seed Count & Coverage Area
Standard packets contain 50-150 seeds, covering a 10-20 square foot bed. Bulk mixes range from 100,000 to 480,000 seeds, designed for 500-1,200 square feet of coverage. Match your seed count to your available planting area. Avoid oversowing—crowded Cleome produces thinner stems and fewer flowers. A rule of thumb: space sprouted seedlings 12-18 inches apart.
