Nasturtiums are the workhorses of the summer garden, delivering spicy edible flowers, round ornamental leaves, and natural pest-repelling properties from a single planting. But not all seed packets are created equal — the difference between a handful of weak seedlings and a cascade of vibrant color starts with variety selection, seed freshness, and bulk quantity.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. I spend my time dissecting botanical specs, comparing germination test data, and aggregating owner feedback from hundreds of verified reviews to separate high-performing seed lines from overpriced duds.
After analyzing bulk offers, heirloom pedigrees, and real-world germination rates across five top contenders, I’ve built this guide to help you confidently pick the right alaska nasturtium seeds for your garden beds, containers, and edible landscaping projects this season.
How To Choose The Best Alaska Nasturtium Seeds
Nasturtiums are forgiving plants, but picking the wrong seed packet can mean wasted space, poor germination, or mismatched growth habits. Focus on these key factors before clicking buy.
Bush vs. Trailing Growth Habit
Alaska Series nasturtiums are known for their variegated foliage, but within the species you’ll find both compact mounding types (ideal for borders and small containers) and trailing vines that can stretch up to 60 inches. Check the listed mature height and spread — a 12-inch mound fits a window box, while a 60-inch trailer belongs on a trellis or hanging basket.
Seed Count and Bulk Value
Packets range from 1 ounce to a full pound. A 4-ounce packet typically holds 700 to 800 seeds, enough to cover 80 square feet of garden space. If you’re planting multiple beds or sharing with neighbors, a larger bulk bag saves money per plant. Just verify that the seeds are fresh — check the packaging date or germination guarantee.
Germination Rate and Seed Preparation
Nasturtium seeds have a hard outer coat. Professional growers often soak seeds overnight or lightly scarify them before planting to improve germination speed. Look for packets that claim a tested germination rate above 90% and include instructions for pre-soaking. Lower-cost seeds may still sprout, but you’ll get faster, more uniform results with properly handled stock.
Edibility and Flavor Profile
All nasturtium flowers and leaves are edible, but some varieties produce a stronger peppery kick similar to watercress or radish. If you’re growing for salads and garnishes, choose a mix that explicitly notes its culinary use. The Alaska series generally delivers milder, pleasant heat that won’t overpower a dish.

In-Depth Reviews
1. Outsidepride Jewel Mix Nasturtium Seeds
The Outsidepride Jewel Mix delivers a full pound of seeds — enough to cover hundreds of square feet with compact mounding plants that reach 12 to 14 inches tall and trail up to 60 inches. Blooming from mid-summer through fall, the 2-3 inch flowers come in shades of red, orange, and yellow atop rounded foliage that thrives in full sun and well-drained soil (pH 6.1 to 7.8).
Germination occurs within 7 to 10 days at 68°F when sown 1 to 2 seeds per plant with 8 to 12 inch spacing. The flowers, leaves, and seeds are all edible with a zesty peppery punch, making this a dual-purpose ornamental and culinary crop. Verified buyers confirm that these seeds germinate reliably year after year, with many reporting fast blooms that latch onto trellises within a month.
Companion planting benefits are substantial — the peppery scent deters aphids and squash bugs while attracting bees, butterflies, and hummingbirds. The only real downside is the sheer volume: a 1 lb bag is excessive for a single small garden unless you plan to share or store for multiple seasons.
What works
- Massive 1 lb quantity with uniform, high germination
- Edible flowers and leaves with strong peppery flavor
- Dual growth habit — compact mounds and trailing vines
What doesn’t
- Bag size is excessive for small-space gardeners
- Requires full sun for optimal bloom density
2. Seed Needs Bulk Collection Jewel Blend & Double Gleam
Seed Needs bundles two distinct varieties into one order: Jewel Blend (compact mounding, 12-18 inches tall) and Double Gleam (trailing up to 60 inches wide). This gives you both border fillers and cascading vines in a single purchase — ideal for gardeners who want variety without buying separate packets. The semi-double to double blooms span red, yellow, orange, and gold.
The seeds are open-pollinated heirlooms packaged in tear-resistant, moisture-proof envelopes with art illustrations and detailed sowing instructions on the reverse. Growers report germination in roughly one week, with seedlings sprouting vigorously under grow lights or direct sun. The edible flowers and leaves carry a distinctive peppery note that works well in salads, sandwiches, and garnishes.
One caveat: the Double Gleam variety benefits from pod removal before planting to improve germination, while Jewel Blend responds well to an overnight soak. A few verified reviews note slightly imperfect germination rates compared to single-variety packets, so expect around 80-85% sprout success rather than the near-perfect rates of some competitors.
What works
- Two growth habits in one purchase — mounding and trailing
- Heirloom seeds in durable, moisture-resistant packaging
- Edible flowers attract pollinators and deter pests
What doesn’t
- Trailing variety may need pod removal for best results
- Germination rate slightly lower than single-variety packs
3. Sweet Yards Tip Top Mix Nasturtium Seeds
The Sweet Yards Tip Top Mix packs more than 800 pure live seeds into a 4-ounce resealable packet, enough to transform 80 square feet into a warm-toned landscape. The Tip Top variety produces vibrant edible blooms in orange, yellow, and red with the classic rounded leaves and trailing growth that nasturtiums are known for. Full sun and well-drained soil are the only real requirements.
The packaging is a standout feature — premium gifitable design with a reusable zipper and complete planting instructions printed on the packet. Sweet Yards also offers a 30-day germination guarantee: if the seeds don’t sprout, they’ll refund without questions. Verified buyers report sturdy, vigorous seedlings that germinate within days under grow lights or in direct-sown beds.
At roughly 800 seeds per packet, this is a strong mid-tier option for gardeners who want generous coverage without committing to a full pound. The main trade-off is the premium price per ounce compared to budget bulk options, though the germination guarantee offsets that risk considerably for first-time nasturtium growers.
What works
- 800+ seeds with 30-day germination guarantee
- Premium resealable packaging with clear instructions
- Vibrant Tip Top Mix colors — orange, yellow, red
What doesn’t
- Higher cost per ounce than bulk alternatives
- Mixed reports on exact seed count vs. stated 800
4. Organo Republic Nasturtium Seeds Pack 4 oz
Organo Republic’s 4-ounce packet contains over 700 non-GMO heirloom nasturtium seeds sourced from domestic suppliers and packaged in a Florida family-owned facility. The waterproof, resealable bag protects seeds from sunlight and moisture, and each package includes scannable QR codes linking to an online growing guide — a helpful touch for beginners who want step-by-step instructions.
The seeds undergo rigorous germination testing with a claimed rate above 90%, and the packaging is sealed to maintain viability for up to two years. Verified buyers consistently report that all planted seeds germinated without soaking or scoring, with one user noting successful squash bug repellent effects when planted as a companion crop around vegetables.
At roughly 700 seeds per packet, this is a solid value proposition for gardeners covering medium-sized beds or containers. The only common complaint is that the resealable bag, while functional, lacks the premium aesthetic of competitors’ art-printed packets — a minor issue for those who prioritize seed quality over packaging beauty.
What works
- Excellent germination rate — many users report 100% sprout success
- QR code growing guide ideal for first-time growers
- Waterproof resealable packaging preserves freshness
What doesn’t
- Basic packaging lacks visual appeal of competitor packets
- Bag may be difficult to reseal tightly after multiple uses
5. Seedphony Nasturtium Seeds Pack 4 oz
Seedphony offers a 4-ounce packet of non-GMO heirloom nasturtium seeds in a waterproof, resealable pouch designed to preserve freshness for up to two years. Like the Organo Republic option, it includes scannable QR codes linking to an online growing guide. The seeds are sourced from American growers and tested to achieve a germination rate above 90%.
Real-world results from verified buyers show a slightly wider germination range — typically 65% to 75% with direct sowing, though one user reported 4 out of 4 seeds germinated in 8 days. Several reviewers note that the actual weight measured 3.8 ounces rather than the advertised 4 ounces, though the seed count remains generous. The flowers and leaves are edible with a spicy, radish-like flavor, and the plants tolerate frost, neglect, and thunderstorms once established.
This is a budget-friendly entry point for gardeners who want a large quantity of seeds without committing to a premium-priced brand. The main trade-off is inconsistent variety labeling — buyers don’t always know whether they’re getting mounding or trailing types until the plants mature. If you’re flexible on exact growth habit and want maximum seeds for minimal cost, this pack delivers.
What works
- Generous 700-seed count for a budget price
- Waterproof resealable pouch with QR guide
- Tough plants that survive frost and neglect
What doesn’t
- Actual weight may be slightly under 4 ounces
- Variety type (bush vs. trailing) not specified on packet
Hardware & Specs Guide
Seed Count and Coverage
Nasturtium seed packets range from 350 seeds (Seed Needs mix) to a full pound (Outsidepride Jewel Mix). A 4-ounce packet typically holds 700 to 800 seeds, covering roughly 80 square feet when spaced 8 to 12 inches apart. For small containers or window boxes, 100 to 200 seeds suffice. For large beds or ground cover, aim for 500 seeds or more.
Growth Habit — Mounding vs. Trailing
Compact mounding varieties like Jewel Blend reach 12 to 18 inches tall and work best in borders, edging, and small containers. Trailing varieties like Double Gleam can spread up to 60 inches, making them ideal for hanging baskets, trellises, and rock gardens. Some mixes (e.g., Seed Needs) combine both habits in one packet, offering flexibility for multi-zone planting.
Germination Preparation
Nasturtium seeds have a hard outer coat that benefits from soaking in water for 8 to 12 hours before planting. Scarifying (nicking the seed coat with a file) can further speed germination. Ideal soil temperature is 68°F, with germination occurring in 7 to 10 days. Seeds planted in poor, well-drained soil with full sun produce the most blooms.
Edibility and Flavor Notes
All parts of the nasturtium plant — flowers, leaves, and seeds — are edible. The flavor is peppery and slightly sweet, similar to watercress or radish. Flowers add visual appeal to salads and sandwiches, while leaves can be used as a spicy wrap. The seeds can be pickled and used as a caper substitute. Ideal pH range for optimal growth is 6.1 to 7.8.

Final Thoughts: The Verdict
For most gardeners, the alaska nasturtium seeds winner is the Outsidepride Jewel Mix because its 1 lb bulk quantity, dual mounding-and-trailing growth, and near-perfect germination rate offer unmatched value for season-long coverage. If you want two distinct varieties in one purchase, grab the Seed Needs Bulk Collection. And for a budget-friendly entry point that still delivers 700 seeds in waterproof packaging, the Seedphony 4 oz Pack is a solid choice for beginners or mass plantings.
