Considering giant granadilla seeds for a tropical vine project? This listing currently advertises 60 seeds under the common names giant granadilla, badea and barbadine. These names commonly refer to Passiflora quadrangularis, a large climbing member of the passionflower family. The botanical identity of this physical seed lot has not yet been authenticated. The SKU and older marketing material contain conflicting quantity information, so the physical count and packet configuration need verification before fulfillment.
If the seeds are confirmed to be P. quadrangularis, gardeners should plan for a vigorous, tropical, frost-sensitive vine with extensive climbing support. The Royal Horticultural Society describes giant granadilla as an ornamental tropical climber that may bear large fruit in suitable conditions, but fruit set outside the tropics is often unreliable. These are species-level facts, not guarantees about this lot's germination, fruit flavor, yield, flower color or edible use.
Seeds only: This purchase does not include a live plant, a rooted cutting, a trellis or harvested fruit. Confirm the species before deciding whether the plant is suitable for your climate and any local planting restrictions.

Giant Granadilla vs. Other Passionflowers
The name “granadilla” is shared by more than one Passiflora. Giant granadilla conventionally refers to P. quadrangularis; purple granadilla often refers to a form of P. edulis; other passionflowers have different flower structures, fruit characteristics and cold tolerance. It is easy for seed sellers to reuse photographs and common names across these plants, which is why the actual supplier lot is the decisive evidence.
RHS information on P. quadrangularis describes a large, angled-stemmed evergreen climber, attractive flowers, and tropical culture. It should not be confused with P. incarnata, a more cold-tolerant North American passionflower, or with commercially grown P. edulis. A photograph of a large fruit does not prove a packet belongs to the giant granadilla species. Do not make assumptions about seed identity, fruit edibility or winter hardiness from the picture alone.
Important for Florida Gardeners: Check Local Invasiveness Guidance
The University of Florida's IFAS Assessment classifies Passiflora quadrangularis as a high invasion-risk species for North, Central and South Florida and does not recommend it for Florida gardening. The university notes that the vine can climb aggressively and shade other vegetation. If the seed lot is confirmed as this species, review local guidance before planting or distributing it; avoiding release into natural areas is especially important. The fact that a species is marketed online does not itself establish ecological suitability for every location.
The current lot's identity is still unverified. This warning is therefore a specific, conditional precaution about P. quadrangularis, rather than proof that the product contains it. Gardeners outside Florida should also check local extension and invasive-species guidance before planting any vigorous non-native vine.
Eight Steps to Start a Well-Documented Trial
- Verify the seed lot first. Compare the supplier label, botanical name, seed count, packing date and lot code against the Shopify record. The current title says 60; the SKU and legacy copy have carried different quantities. Preserve a photo of the physical label and record what is actually being sold.
- Choose a controlled starting setup. Use small pots or cells with holes and a tray that allows excess water to drain. Starting inside a protected propagation space makes it easier to monitor moisture and manage cold exposure than direct-sowing an unknown passionflower into an outdoor bed.
- Fill with fresh, well-draining medium. A clean seed-starting mix is preferable to heavy, compacted garden soil. University extension material on indoor seed starting emphasizes aeration, cleanliness and drainage to reduce seedling problems.
- Decide on pre-treatment from the verified species. Passionflowers may have seed coats that make germination variable, and some guides discuss soaking. However, the exact seed age, storage history and species here are unknown. Seek lot-specific guidance before soaking, nicking or scarifying; do not damage an entire packet based on an unrelated passionflower example.
- Sow, label and monitor carefully. Follow a confirmed species' depth and temperature guidance. Label each container with sowing date, seed source, seed count and any treatment used. Record actual conditions, rather than quoting an unsupported germination timetable.
- Keep the medium moist but airy. Check daily for excessive dryness, standing water, fungal growth and overheated covered trays. Adjust drainage and ventilation as needed; avoid persistently saturated roots.
- Wait for establishment before transplanting. Germination may be uneven. Allow new seedlings to become sturdy, develop true leaves and build sufficient roots, then change their light and outdoor conditions gradually. Protect from sudden bright sun, cold wind or frost.
- Use a movable container until identity is confirmed. If the plant is indeed P. quadrangularis, provide a large, secure support and a location appropriate to tropical culture where planting is locally recommended. In places where it is invasive or discouraged, do not establish it outdoors.
Growing the Confirmed P. quadrangularis: Space, Warmth and Support
This section applies only if the physical seed lot is positively identified as Passiflora quadrangularis. RHS describes it as a vigorous climbing species, potentially growing above 12 metres in suitable conditions. It is better approached as a sizeable perennial vine project than as a small windowsill herb. Before transplanting, plan the height, weight, access and maintenance of a sturdy trellis or overhead support.
Warmth and winter protection: RHS places this species among the tender edible passionflowers for heated greenhouses or conservatories. Its profile recommends protected growing and a minimum of about 13°C (55°F) under glass, while the RHS edible passionflower guide recommends tropical winter conditions and warns against temperatures below approximately 15°C (59°F) for dependable culture. These are established-plant cultivation references, not a validated germination temperature or cold-hardiness claim for this seed lot.
Light: Good light is needed, but glasshouses can overheat. RHS advises shading from harsh direct midday sun under glass where leaves scorch. Young seedlings coming from indoor conditions should be acclimated gradually before stronger exposure. Soil and containers: Use a freely draining, fertile potting medium suitable for a large climber, and select containers that can be moved to protected conditions when necessary.
Watering: Keep actively growing vines adequately watered while permitting drainage. In cooler, less active periods, reduce excess watering to avoid stagnant conditions. A fixed watering frequency will be wrong for some pot sizes, seasons and humidity levels. Check the actual root zone, drainage and plant response.
Why Fruiting Is Harder Than Growing a Vine
Large leaves and vigorous vines can look impressive even when fruit never develops. RHS notes that giant granadilla rarely sets fruit outside the tropics and may need warm protected conditions. University of Florida Extension describes the difficulty of obtaining fruit in some garden settings and the possible need for hand pollination. Fruit set also depends on mature flowering plants, suitable pollination and an appropriate growing environment.
Giant granadilla has appealing flowers and potential fruit as a species, but this listing cannot promise that any particular seed will produce the photographed flower or large fruit. A seed-grown plant can differ from its parent. Do not advertise a guaranteed crop, fixed ripening window or flavor profile without cultivar and seed-lot evidence. The correct species must be authenticated before discussing edibility.
Giant granadilla flowers but no fruit? Check the flower-to-fruit stage first
Direct answer: A flowering giant granadilla vine does not automatically produce fruit. First identify whether flowers never fully open, open and drop without a swelling ovary, or start a small fruit that later drops. Check flower development, the actual pollination attempt and environmental stress before changing fertilizer or promising a harvest. This is guidance for correctly identified Passiflora quadrangularis; the botanical identity and performance of this retail seed lot remain unverified.
Observed grower question, not proof of cause: In a February 2012 grower discussion about giant granadilla, a gardener reported abundant flowers but few fruits despite attempting hand pollination. That report confirms the question exists; it does not establish a diagnosis, search volume, or expected results for these seeds.
| What you observe | Check before acting | Reasonable next decision |
|---|---|---|
| Vine grows vigorously but has no open flowers | Confirm plant maturity and species; record light, climate, growth stage and whether flower buds are present. | Treat this as a flowering-stage question, not proof of a pollination failure; seek local, species-specific guidance before intervention. |
| Flowers open but no young fruit becomes visible | Photograph flowers on successive days and document whether pollen transfer was observed or attempted. Note weather during the bloom. | Pollination may warrant investigation. University of California Cooperative Extension identifies P. quadrangularis as often hand-pollinated, but this is not a promise that hand pollination will solve every case. |
| Hand pollination was tried but flowers still drop | Confirm the flower and pollen source belong to the correctly identified species; keep dated records of the bloom, attempt and subsequent development. | Do not conclude that more fertilizer, more bees, or a specific time of day is the missing factor. Request local horticultural diagnosis when repeated attempts fail. |
| Small fruits form and later stop developing or fall | Check for visible damage and major environmental changes; document waterlogging, drought or temperature extremes without assigning a cause from one event. | Investigate fruit retention separately from initial pollination. Avoid unverified treatment or guaranteed yield claims. |
Before planting or propagating: University of Florida IFAS assesses P. quadrangularis as high invasion risk in Florida. Do not treat these troubleshooting steps as a recommendation to establish or spread this species outdoors where local guidance advises against it. Exact seed species, pack quantity (the title says 60; the historical SKU says 100), pollination characteristics and harvest potential still require independent supplier or physical-lot evidence. No particular fruit set or edibility is guaranteed.
Containers vs. Outdoor Planting: A Decision Guide
| Growing situation | Key decision before planting | Recommended approach |
|---|---|---|
| Apartment or patio | Space and support for a vigorous vine | Begin in a movable container and plan where mature growth will be supported; confirm species |
| Heated greenhouse | Winter temperatures, airflow and light | Follow verified species guidance, watch summer overheating and give strong trellis support |
| Temperate outdoor garden | Frost exposure and ability to overwinter | Do not assume winter hardiness; container culture may allow protective relocation where planting is appropriate |
| Florida outdoor landscape | UF/IFAS high invasion-risk classification for P. quadrangularis | Avoid outdoor establishment of confirmed P. quadrangularis; consult current local extension advice |
| Fruit-focused planting | Verified species, pollination and suitable warm conditions | Do not plan yield or edibility from this unresolved seed lot; seek confirmed cultivar material first |
Troubleshooting Seedlings and Young Vines
- No seedlings after expected waiting: Confirm seed identity, age, moisture and the applicable germination procedure. Do not assume a packet is dead from a generic timeline or respond by flooding the tray.
- Mold on medium: Look for waterlogged cells, poor air circulation and contaminated material. Improve sanitation and ventilation; replace severely compromised batches rather than transferring them to the permanent garden.
- Thin, weak or leaning stems: Check light level, crowding and absence of support. Increase suitable light gradually and add gentle support as appropriate.
- Brown, crisp edges after a move: Look for sudden sun exposure, dry potting mix or hot glasshouse conditions. Shade and acclimate stressed plants progressively.
- Yellow leaves with constantly wet soil: Check drainage and roots. Reduce standing water and refresh poorly aerated medium if necessary.
- Fast growth that overwhelms its support: Identify the vine and re-evaluate container size, trellis strength and local spread risk. Do not allow unwanted growth into nearby natural areas.
- Flowers but no fruit: Confirm species and maturity, investigate pollination and growing conditions, and recognize that fruiting is not guaranteed even on healthy tropical vines.
Frequently Asked Questions
Is giant granadilla the same as purple passion fruit?
No. Giant granadilla commonly refers to Passiflora quadrangularis, whereas the commonly grown purple passion fruit is generally associated with P. edulis. This listing's exact physical seed lot still requires verification.
Are these definitely Passiflora quadrangularis seeds?
The product title and common names suggest that species, but the present physical lot lacks independently verified botanical documentation. Keep the identity unconfirmed until the supplier record and packet label agree.
How many seeds or packets are included?
The current title advertises 60 seeds. Older SKU and marketing records describe other amounts. The store must confirm the physical count and packet configuration before promising the final quantity.
Can I plant these outdoors in Florida?
If the species is confirmed as P. quadrangularis, UF/IFAS assesses it as high invasion risk and does not recommend it for Florida gardens. Check current local guidance and avoid releasing plants into natural areas.
Is giant granadilla frost hardy?
Verified P. quadrangularis is tropical and frost-sensitive. RHS recommends warm protected conditions. It should not be treated like a cold-hardy maypop or marketed with a specific USDA zone before identity is confirmed.
Will these seeds produce giant edible fruit?
No fruit outcome is guaranteed. The actual species, pollination needs, maturity, growing conditions and lot viability are unverified. Do not eat fruit from an unidentified passionflower.
What is the best germination temperature or soaking time?
There is no documented lot-specific protocol. Select the method only after identifying the seed and consulting an appropriate species propagation source. Avoid damaging all seeds with an untested treatment.
Do I need a trellis?
Confirmed P. quadrangularis is a vigorous climbing vine and needs substantial support. An unidentified Passiflora should be evaluated for mature habit before choosing its permanent location.
Are the seeds organic, heirloom, non-GMO or germination tested?
Those claims have no verified supplier documentation for this lot. No minimum germination percentage, certification or cultivar purity is promised.
