That classic morning glory blue with a crisp white edge — the Picotee look — feels like the gardener’s version of a tailored suit. The problem is most seed packets promise that bicolor contrast but deliver a washed-out blue or a solid tone that blends into every other trellis on the block. You don’t want another vine. You want the one that stops people mid-walk.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. I’ve spent years digging through seed stock data, cross-referencing germination claims with real customer germination reports, and studying the genetics behind blue pigmentation in morning glory varieties.
Whether you are covering a fence, an arbor, or a garden wall, the picotee blue morning glory demands a seed source that actually delivers that white picotee edge on every single bloom, not just on the seed packet photo.
How To Choose The Best Picotee Blue Morning Glory
Morning glory seeds look nearly identical from one packet to the next, but the genetic consistency of the picotee trait varies dramatically between suppliers. A true picotee bloom has a deep violet-blue center that transitions to a pure white border — if the seed stock has been cross-pollinated with solid blue varieties, you lose that white edge within a generation. Here are the filters that matter.
Verify the Variety Name Ipomoea tricolor
Not all blue morning glories are Ipomoea tricolor. Some cheaper mixes use Ipomoea purpurea, which rarely displays a clean picotee edge. Always check the botanical name on the packet. If it says Ipomoea tricolor and the specific variety name includes “Blue Picotee,” you are buying the correct genetic line.
Check the Seed Coat Treatment
Morning glory seeds have a notoriously hard outer shell that delays germination. Soaking for 24 hours in warm water is standard, but some premium seed suppliers pre-scarify the seed coat. If the listing says “untreated,” you must nick or soak the seeds yourself. Pre-scarified seeds shave 3–5 days off the germination window.
Look for Fresh Stock, Not Shelf Relics
Morning glory germination rates drop sharply after two years of storage. A packet sitting on a garden center shelf for multiple seasons can have 50% or lower germination regardless of the brand. Amazon listings with frequent recent reviews and temperature-controlled storage claims (like refrigeration) are a better bet than unbranded clearance bins.
Prioritize Open-Pollinated or Heirloom Tags
Seeds labeled “heirloom” or “open-pollinated” produce plants that remain true to type year after year. Hybrid or mixed-color packs can produce a spectrum of colors, often losing the specific picotee pattern. If you want consistent picotee blooms, stick to single-variety heirloom listings.

In‑Depth Reviews
1. Eden Brothers Morning Glory Seeds — Blue Picotee
Eden Brothers is the most reliable source for the true Blue Picotee pattern — azure blue petals with a clean white edge — because they sell it as a single named variety rather than a mixed batch. The 1-ounce packet contains roughly 800 untreated seeds, all non-GMO and heirloom, which means the picotee genetics remain stable across generations. Customer reports consistently describe “spectacular” flowers with the white picotee border intact, unlike cheaper blends where the white edge disappears.
The germination rate is high when the seeds are soaked for 24 hours before planting, and the vines easily exceed 10 feet in good soil with full sun. Several reviewers noted that the leaves grow larger than expected, which helps create dense coverage on trellises. One minor complaint involves the color matching expectations — one reviewer received pale blooms instead of deep blue, which can happen with pH variations in the soil, but the majority report deep true-blue flowers.
This seed line supports USDA zones 1 through 10, making it one of the most adaptable morning glory varieties available. The only drawback is the 1-ounce size is moderate — if you are covering a very large fence, you might need two packets. Still, for a gardener who wants guaranteed picotee pattern and heirloom purity, Eden Brothers is the standard.
What works
- True picotee edge confirmed by multiple customer photos
- Heirloom open-pollinated seeds maintain color consistency
- Vigorous growth to 10 feet with dense leaf cover
What doesn’t
- Soil pH can shift blue tones toward pinkish shades
- 1-ounce packet is moderate for very large areas
2. Seed Kingdom Morning Glory Heavenly Blue — 1 Lb
Seed Kingdom’s 1-pound bag is the highest-volume option in this roundup, offering approximately 3,000 untreated seeds of Ipomoea tricolor. This is a true Heavenly Blue — solid sky-blue blooms with white throats, not a mixed picotee — but the massive quantity makes it ideal for gardeners who want total fence coverage without buying multiple packets. The seeds arrive in a simple clear ziploc bag, which is functional but not resealable in a heavy-duty sense.
The germination rate is consistently high when pre-soaked, and multiple reviews confirm that the variety is correctly identified as I. tricolor, avoiding the confusion that sometimes occurs with generic morning glory labels. One reviewer noted that despite correct species ID, the bloom color leaned slightly different from classic “heavenly blue,” potentially due to soil conditions. The plants are described as healthy and robust, climbing quickly once established.
The main inconvenience is the packaging: a clear bag exposes seeds to light, which can theoretically reduce viability if stored improperly. Transferring them to a dark, airtight container is a simple fix. For gardeners prioritizing quantity and cost-per-seed efficiency over ornamental picotee patterns, this bag delivers unmatched volume.
What works
- Extremely high seed count for large-area planting
- Correct Ipomoea tricolor genetics verified by buyers
- Untreated seeds for gardeners seeking pure organic stock
What doesn’t
- Clear bag may cause light exposure during storage
- Solid blue blooms — not a true picotee pattern
3. HOME GROWN Morning Glory Seeds — Heavenly Blue 2-Pack
HOME GROWN’s two-pack offers 300 heirloom seeds of Heavenly Blue, making it an excellent entry point for gardeners who want a solid blue morning glory without committing to bulk sizing. The seeds are non-GMO and sourced in the USA, with a high germination rate confirmed by multiple reviewers who reported near-100% sprouting within a week. The included online grow guide adds value for beginners who may be unfamiliar with the pre-soaking technique.
The packaging is straightforward — two resealable foil packets that protect seeds from moisture and light, which is superior to simple clear bags. The “Heavenly Blue” variety produces classic sky-blue flowers with white throat centers, not a picotee pattern, but the bloom quality is consistent and the vines grow densely enough to cover chain-link fences quickly. A few reviewers noted that the second packet could have been larger, but at this price point the per-seed cost is reasonable.
One minor caveat: some customer reviews are actually about other HOME GROWN products (beans, tomatoes) that were aggregated under this listing, so take anecdotal claims with a grain of salt. Still, the verified reviews specifically about this morning glory pack report vigorous growth and abundant blooms. It is a solid, no-fuss option for a blue fence cover.
What works
- Foil packaging protects seeds from light degradation
- High germination rate reported within 7 days
- Compact two-pack ideal for smaller gardens or testing
What doesn’t
- Listing mixes reviews from other HOME GROWN seed types
- Blue color is classic sky blue, not picotee bicolor
4. Outsidepride Heavenly Blue Morning Glory — 1/4 Lb
Outsidepride’s 1/4-pound bag of Heavenly Blue seeds produces flowers that reach 5 inches across — slightly larger than the typical 3-4 inch morning glory bloom. The vines grow rapidly to 8-10 feet and are noted for drought tolerance once established, making them suitable for rocky or sandy soil where other annuals struggle. The seeds are untreated and GMO-free, and the packaging includes a clear germination expectation of 80%.
The bloom period extends from early summer into fall, and the white throat on each blue flower provides a subtle contrast against the blue petals — not a true picotee, but visually lighter at the center. Customers praised the professional packaging and accurate weight. One buyer noted that the variety is invasive if allowed to self-seed aggressively, which is common for morning glories in general. For container or active gardeners, this is manageable but worth knowing upfront.
The only downside reported is that some seeds did not bloom in the first season, possibly due to planting timing or soil conditions. The 1/4-pound bag provides good value for medium-to-large trellises without the oversupply of a full pound. For drought-prone gardens that still want a reliable blue annual vine, Outsidepride delivers.
What works
- Large 5-inch blooms stand out more than standard varieties
- Drought-tolerant after establishment
- Accurate weight and professionally packaged
What doesn’t
- Can become invasive with aggressive self-seeding
- Some seeds may not bloom in the first season
5. Marde Ross & Company Mixed Morning Glory Seeds
Marde Ross & Company’s mixed morning glory seeds are a multi-color blend spanning shades of blue, purple, pink, rose, and white, with approximately 160 seeds per packet. This is not a pure blue or picotee variety, but for gardeners who want a tapestry of colors on a single trellis, this mix creates a vibrant and unpredictable display. The seeds are stored in temperature-controlled refrigeration to maintain freshness, and the brand has been a California nursery since 1985.
One of the standout customer stories here involves a vine planted in July that overtook a trellis by August and bloomed continuously through October in multiple colors. The 3-11 hardiness zone range is wide, and the vines reach 8-12 feet with dense heart-shaped leaves. A reviewer mentioned that soaking overnight improved germination, which is consistent with all morning glory seeds. The untreated, GMO-free status appeals to organic growers.
The trade-off is that because these seeds are mixed, you cannot guarantee any specific color outcome. If you are specifically looking for a pure blue or picotee, choose a single-variety packet. But for a viewer-stopping fence display with multiple trumpet colors, this mix is the most lively option in this roundup.
What works
- Multi-color mix creates a visually rich tapestry
- Temperature-controlled storage preserves germination
- Rapid growth — can overtake a trellis within weeks
What doesn’t
- No color consistency — each bloom may differ
- One reviewer reported zero germination
Hardware & Specs Guide
Seed Pretreatment: Soaking & Scarification
Morning glory seeds have a water-impermeable seed coat. Without soaking, germination can take 2-3 weeks. The standard method is to soak seeds in warm water (not boiling) for 24 hours. Some gardeners also nick the seed coat with a nail clipper — this physical scarification can reduce germination time to 5-7 days. Untreated seeds (most of the options above) require this step. Pre-scarified seeds are rare but exist in some specialty lines.
USDA Zone Compatibility
Ipomoea tricolor is a tender perennial in zones 10-11 but grown as an annual everywhere else. Most morning glory seeds will sprout in zones 3-11. The key zone threshold is frost: morning glories are frost-sensitive and should be planted after the last frost date. In cooler zones (3-5), start seeds indoors 4-6 weeks before last frost to extend the blooming window. The Eden Brothers Blue Picotee is the most zone-flexible option at zones 1-10.
