Vigna caracalla, also referred to as corkscrew vine, snail vine or corkscrew flower, creates beautiful aromatic flowers and is native to South America. The continuing flowering vine will climb to a height of up to 20 feet and produces clusters of snail-shaped flowers, which last from May until August. These flowering vines succeed in USDA zones 9 and 10, according to the Desert Tropicals site. Like many legumes, Vigna caracalla will triumph in many conditions and is simple to grow from seed.
Use a sharp knife or razor blade to cut the hull of every Vigna caracalla seed. Don’t cut on the hull too deep, as the seed could be harmed by this.
Place the seeds into a bowl of water about 1-inch deep, and allow the seeds to boil for approximately 24 hours. This permits the seeds to soften and assimilate the seeds for germination.
Fill a seedling flat or several pots with potting soil. Allow the dirt to reach around 70 degrees, and Put the seedling pots or flat near a window F.
Place the seeds about weeks before the last frost, and mist the soil’s top with water. Use a spray bottle to avoid overwatering. Overwatering can rot the seeds.
Spray the top of the soil with water to another 15 days. Enough water on the soil to keep it moist but not soaking wet. Water daily until spouts look, then decrease the watering other day. Always keep the top of the soil moist and avoid allowing the soil to dry out.
After all risk of frost has passed, plant the corkscrew vine seedlings. In which the vines will have help, place the seedlings from sunlight close to a wall or trellis. The vine requires a minimum of eight hours of sunshine a day for the best results. Plant the seedlings approximately 1 to 2 feet.
Employ a fertilizer to the soil every February for fuller, brighter blooms. The blossoms will range to cream in colour from purple in colour.
