Passion Flower Plant Live, Burgundy Red
The AVERAR Passion Flower Plant arrives as a 5 to 8 inch tall, well-rooted starter without a pot. This vigorous climber is noted for tropical-looking blooms and rapid growth, making it ideal for trellises, fences, and other supports. It thrives in full sun to partial shade and blooms from late spring through summer. It is cold-hardy in USDA Zones 6-10 and can be maintained with regular watering to promote strong vine development and blooms.
Scarlet Flame Passion Flower Vine
Scarlet Flame is a Passiflora coccinea hybrid offering large red blooms with a white crown fringed in short red filaments. This tropical vine features a profusion of vibrant, nectar-rich flowers that attract hummingbirds and other pollinators. It is generally grown for its vigorous, easy-care habit and spectacular blossoms. While fruiting is possible, it typically requires hand pollination. For best results, plant in partial shade with fertile, well-draining soil and provide a trellis or support. Regular watering and spring fertilization help maintain bloom quality.
Red Passionflower Vine Seeds (Passiflora princeps)
These seeds bring the striking Passiflora princeps, or Passiflora racemosa, to home gardens. The plant develops slender stems that climb to about 10 meters high, with simple or trilobed, leathery leaves and vivid red-to-pinkish-red flower racemes. Seeds are prepped to plant, and included instructions guide growers through germination. The cultivar is native to the Atlantic Coastal Forest in southeastern Brazil, where it enjoys a mild tropical climate. Gardeners should provide warmth, sun, and a trellis to support robust vertical growth and showy blooms.
Blue Passion Flower Seeds (Passiflora caerulea)
The Blue Passion Flower seeds feature intricate flowers with a striking corona of blue and white filaments. This variety is known for vigorous growth that quickly climbs trellises, fences, or walls, adding an unmistakable tropical flair to sunny gardens. It tolerates a range of conditions but performs best in full sun and well-drained soil. Regular watering and a bloom-boosting fertilizer in spring support prolific flowering, while routine pruning helps manage size and shape for vertical displays.
Ruby Glow Passion Flower Vine
Ruby Glow is a tropical Passiflora species with a fast, vigorous growth habit. It produces exceptionally large blooms in a deep purple-maroon tone, accented by long violet-blue and white filaments. The plant tends to establish quickly into a dense, lush climber that thrives with basic care and regular watering. Pollination to fruiting may require a partner cultivar. Plant in partial shade with fertile, well-draining soil, and provide a sturdy trellis. As with other passion flowers, pruning after flowering helps control size and encourages continued bloom.
Incense Passion Flower Vine
Incense is a Passiflora incarnata hybrid known for fragrance and nectar-rich blooms. This hybrid tends to be slower-growing yet still prolific in producing violet-to-blue-toned flowers that attract a wide range of pollinators. Fruiting is possible but may require hand pollination with a different Passiflora species. Gardeners should choose partial shade with fertile, well-draining soil and use a trellis or support. Regular watering and spring fertilization improve vigor, while post-flowering pruning maintains compact size and encourages ongoing bloom cycles.
Buying Guide: Key Purchase Considerations
- Climate and hardiness: Match the plant’s USDA zone range with your locale (Zones 6-10 are common for many crimson varieties). In colder regions, consider potted options that can be overwintered indoors or moved indoors during frosts.
- Bloom color and fragrance: Crimson, scarlet, and violet tones vary by cultivar; decide whether you want bold red clusters, deep purple blooms, or blue filaments for contrast.
- Growth habit and support: Passion flowers require sturdy support like a trellis, fence, or pergola. Consider vine vigor, height potential (some reach 10 meters), and whether you prefer a dense screen or a flowering climber for a focal point.
- Sun exposure: Most passion vines thrive in full sun to partial shade. Optimize bloom behavior by ensuring several hours of sun daily.
- Soil and watering: Well-draining, fertile soil supports stronger blooms and fewer issues with root rot. Regular, moderate watering is usually sufficient, with reduced watering after flowering to encourage buildup of new blooms.
- Pollination and fruiting: Some varieties set fruit more readily than others; fruit production may require cross-pollination with a different passion flower cultivar.
- Propagation method: Seeds offer genetic diversity but may require stratification or longer germination times, while cuttings provide faster, more uniform results.
- Pest and disease resilience: Look for varieties with robust resistance to common pests and diseases to reduce maintenance and protect blooms.
