The Lady Margaret Passion Flower isn’t another purple passiflora clone. It’s a Passiflora coccinea hybrid that swaps lavender for deep maroon-red and pastel pink, a combination so rich it pulls the eye from across the yard. But finding a live starter that survives shipping and actually blooms takes more than luck.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. I spend my time studying nursery shipping data, comparing vine genetics and supplier hardening protocols, and analyzing aggregated owner feedback to separate the vigorous starters from the ones that arrive as sad, wilted sticks.
lady margaret passion flower reviews online rarely tell buyers its nectar-rich flowers don’t attract butterfly caterpillars and it’s considered a sterile, non-fruiting vine ideal for pure ornamental display without fruit cleanup or seedling spread.
How To Choose The Best Lady Margaret Passion Flower
Buying a live vine online means trusting that the nursery packed a plant capable of bouncing back from a dark box ride. The coccinea hybrid is more sensitive to shipping stress than common purple types, so every spec matters.
Shipped Size & Root Establishment
A 4-inch pot with a 6- to 10-inch vine is the standard for this hybrid. Anything smaller in a 2-inch plug risks transplant shock. Look for at least three mature leaves and visible roots at the pot’s drainage holes — that’s the sign of a plant hardened beyond the nursery bench.
Bloom Color & Sterility
The Lady Margaret should show deep maroon-red outer petals with a pastel pink-to-white corolla ring. Unlike Passiflora edulis, this hybrid is bred for flower display, not fruit. If you want edible passionfruit, skip this pick and choose a ‘Possum Purple’ instead.
USDA Zone Match & Light Requirements
This vine thrives in zones 8 through 10. It prefers partial shade — morning sun with afternoon shade — unlike full-sun edulis types. In zone 10, a north-facing trellis prevents leaf scorch. Buyers in zone 7 or colder must plan for container overwintering indoors.

In‑Depth Reviews
1. Lady Margaret Passion Flower Vine (Emerald Goddess Gardens)
This is the only pure Lady Margaret in the lineup, a Passiflora coccinea hybrid bred for ornamental display rather than fruit. The deep maroon-red blooms with a pastel pink center appear profusely from spring to fall when grown in partial shade. The vine reaches 10 feet and is generally considered sterile, so there is no fruit drop or invasive seedling spread to manage.
The starter arrives at 6 to 10 inches tall in a 4-inch nursery pot, which gives it a head start over smaller plugs. Shipped packaging from Emerald Goddess Gardens is consistently praised for keeping leaves intact. A California-certified source that grows plants in USA conditions avoids the shock common with mass-imported tropicals.
Customer feedback shows the vine blooms within weeks of planting during the warm season. The one caveat is that a small number of buyers received plants that did not survive transplanting, though replacements are handled through the nursery’s 30-day warranty. For any gardener seeking the exact Lady Margaret look, this is the authoritative listing.
What works
- Authentic maroon-red Lady Margaret hybrid, not a generic purple
- Large 4-inch pot with well-established roots reduces transplant shock
- California-grown stock hardened for USDA zones 8-10
What doesn’t
- Vine is non-fruiting; not suitable for passion fruit harvest
- A minority of reported die-offs after transplant
2. Easy to Grow Passion Flower ‘Betty Myles Young’
The ‘Betty Myles Young’ variety is a purple passiflora backed by Easy to Grow, an American nursery network that ships in quart grower pots rather than the shallower 3- or 4-inch pots common in the category. The larger soil volume means the root ball stays hydrated longer during transit, a distinct edge for buyers in hot summer climates.
Mature vines climb to 10 to 15 feet with fragrant summer-to-fall blooms that lean toward deep purple rather than the red of the Lady Margaret. The plant is perennial in zones 8 through 11 but performs as a vigorous annual in cooler zones. Moderate watering and a sturdy trellis are the only requirements.
Verified buyer reports consistently mention the plant doubling in size within a month after ground planting and already pushing flowers by midsummer. South Florida users recommend morning sun only, as full afternoon exposure causes midday wilting. For a large-rooted starter with proven bloom reliability, this is a strong alternative.
What works
- Quart-size pot provides deeper root system than standard 4-inch nursery pots
- Fragrant purple blooms appear consistently in first growing season
- American-grown with straightforward planting instructions
What doesn’t
- Not a coccinea hybrid; lacks the maroon-red color of Lady Margaret
- May wilt in intense afternoon heat, especially in Florida zones
3. Easy to Grow Passion Flower ‘Victoria’
Victoria is the only entry in this list that combines pink-purple summer flowers with actual passion fruit production, bridging the gap between the pure ornamental Lady Margaret and the fruiting ‘Possum Purple’ vines. It reaches about 8 feet in-ground or a compact 2 to 3 feet in a container, making it the best choice for patio growers who still want fruit.
The quart grower pot and American nursery sourcing are identical to the ‘Betty Myles Young’ listing, so packing quality and root establishment are consistent. The key difference is breeding: Victoria is a Passiflora that sets edible fruit when pollinated, requiring moderate to heavy watering during the fruiting period.
Reviewers note the vine doubles in size within a month and flowers reliably by midsummer. The smaller mature size (8 feet versus 15 feet for other types) means a single obelisk or small trellis is sufficient. The trade-off is a shorter bloom period compared to the non-fruiting Lady Margaret, as the plant diverts energy into fruit set.
What works
- Produces edible passion fruit alongside ornamental pink-purple flowers
- Compact 8-foot vine suits small trellises and container growing
- Quart pot provides larger root mass than typical starter containers
What doesn’t
- Flower color is pink-purple, not the burgundy-red of Lady Margaret
- Fruiting period shortens bloom window compared to sterile hybrids
4. Fam Plants ‘Possum Purple’ 4-Pack
This 4-pack of ‘Possum Purple’ is built for the buyer who wants fast ground coverage or multiple trellises from a single order. Each starter is a self-fertile Passiflora edulis, meaning one plant sets fruit without needing a second vine nearby. The variety produces the classic sweet purple passion fruit, not the ornamental non-fruiting type of the Lady Margaret.
The plants arrive small — about 3 to 5 inches — in well-packed individual containers. Growers consistently report that all four transplants vigorously elongate and leaf out within weeks when planted in sandy, well-drained soil. The mature vine can reach 20+ feet with fragrant white-and-purple flowers that double as a larval host for Gulf Fritillary and Zebra Longwing butterflies.
The primary risk is the small starting size: one verified buyer lost all four despite experienced care. For zones 9b through 11, this 4-pack offers exceptional value for a dedicated passion fruit patch, but it demands more initial coddling than a single larger starter. Pair with a trellis system rated for heavy fruiting weight.
What works
- Four plants per order for coverage and pollination redundancy
- Self-fertile edulis type yields sweet purple passion fruit
- Larval host for Gulf Fritillary and Zebra Longwing butterflies
What doesn’t
- Small starter size requires careful hardening before ground planting
- Mature vine height (20+ ft) demands a sturdy arbor or tall trellis
5. Wellspring Gardens ‘Purple Possum’ Starter
The Wellspring entry is the lowest-cost single vine in this roundup, arriving in a 3-inch pot with 3 to 8 inches of top growth. The ‘Purple Possum’ is a Passiflora edulis type, so it produces the classic fragrant purple flowers and aromatic fruit, not the sterile red bloom of the Lady Margaret. Mature spread can reach 30 feet, making it a candidate for large arbors or fence lines.
Buyer feedback highlights the plant’s vigorous growth after transplanting — several reviews note the vine tripling in size within a short window. The GMO-free label and sandy-soil preference align with typical passiflora care. The compact 3-inch pot keeps initial footprint small, which helps during the first week of acclimation.
The trade-off for the entry-level cost is a higher likelihood of leaf damage during shipping. Some growers lost leaves to shipping darkness or outdoor pests after planting. The 30-day warranty mitigates this risk, but buyers should inspect the crown and any visible roots on arrival and pot up promptly instead of planting directly into the ground.
What works
- Lowest cost entry into a fruiting passion vine
- Proven vigor with reports of tripling in size after transplant
- GMO-free stock suitable for organic garden integration
What doesn’t
- 3-inch pot is the smallest container size, increasing transplant risk
- Some arrivals show leaf damage from dark shipping conditions
Hardware & Specs Guide
Bloom Color & Hybrid Genetics
The Lady Margaret is a Passiflora coccinea hybrid, not a standard Passiflora edulis. The outer petals are deep maroon-red with a pastel pink-to-white center ring, and the long filaments are speckled. This hybrid is generally considered sterile, producing no fruit. This matters if you want ornamental drama without fruit drop or volunteer seedlings, but it means zero edible fruit.
Shipping Size & Pot Volume
Standard Lady Margaret starters ship in a 4-inch nursery pot with 6 to 10 inches of vine above the soil. This is larger than 2-inch plugs or 3-inch pots used by budget brands. A 4-inch pot holds enough soil to buffer moisture for 2 to 3 days in transit. Inspect the soil surface for moss or algae — dry, cracked soil signals the plant was not watered before shipping.
USDA Hardiness & Light Requirements
This hybrid is reliably perennial in zones 8, 9, and 10. Unlike purple passion vines that demand full sun, the Lady Margaret prefers partial shade — morning direct sun with afternoon shade. In zone 10, a north- or east-facing trellis prevents leaf burn. Growers in zone 7 and colder must plan for container overwintering indoors away from frost.
Moisture & Soil pH
Well-draining, fertile soil with a pH between 5.5 and 6.5 is ideal. Overly alkaline soil (pH above 7) causes yellowing leaves and reduces bloom production. Water deeply when the top 1 inch of soil is dry, but avoid standing water — Passiflora coccinea hybrids are more sensitive to root rot than edulis varieties. A layer of organic mulch around the base helps regulate soil moisture.
