If you want to enhance your garden for hummingbirds returning from winter, the corkscrew vine (Cochliasanthus caracalla) is an excellent choice.
This distinctive vine features spiral-shaped, nectar-filled flowers that bloom from summer into fall, making it one of the top choices for attracting hummingbirds. Thriving in USDA zones 9-11, it's ideal for warmer areas where hummingbirds frequent all summer. You can even start corkscrew vine from seeds (available here: corkscrew vine seeds on Amazon).
Caring for corkscrew vine is straightforward; this fast-growing perennial quickly takes root once planted. With just a few simple care tips, you can train it to adorn pergolas, fences, or trellises, filling your yard with its sweet, captivating fragrance.
Why Hummingbirds Are Drawn to Corkscrew Vine
The corkscrew vine is among the best plants for attracting hummingbirds during the hottest months, thanks to its beautiful flowers.
From late spring to fall, corkscrew vine displays its eye-catching spiral blooms, earning it the nickname 'snail vine.' These flowers come in a variety of colors, including white, creamy yellow, and purple.
One gardener praises corkscrew vine as the best hummingbird plant for her LA garden. She loves having it in a container near her patio door, creating a lovely space for observing hummingbirds throughout the day.
Not only is this plant visually stunning, but it also emits a delightful fragrance and attracts a variety of pollinators. The unique flowers bloom for months, especially in warmer regions.
Its scent can carry quite far on a breeze, yet it's not overpowering. The tubular shape of the corkscrew vine's flowers is perfect for hummingbirds' long beaks, just like other hummingbird-friendly flowers such as cape honeysuckle available at Fast Growing Trees.
Bright colors are also key in attracting these birds, which is why many hummingbird feeders are red (like this Walmart hummingbird feeder).
Growing Corkscrew Vine
Native to the tropics of South and Central America, corkscrew vine thrives in warmer climates (USDA zones 9-11) but can also be grown as an annual in cooler areas.
Here are essential care tips for successful growth:
- Position: Provide a structure for your corkscrew vine to climb. While some gardeners train it up a pergola, others use a trellis or fence. Due to its vigorous growth, many opt to grow it in a container to maintain control. These vines thrive in full sun, needing 6-8 hours of direct light daily.
- Soil: Corkscrew vine prefers slightly acidic, loamy, well-draining soil. For container planting, consider using a potting soil like Miracle-Gro. You can also amend the soil with sulfur for acidity.
- Water: Keep your corkscrew vine consistently moist, avoiding waterlogged conditions. It doesn't tolerate drought well and may wilt or shed leaves. If grown in a container, it will dry out faster, requiring frequent watering during hot spells.
- Pruning: Regular pruning helps maintain the size and health of your corkscrew vine. Trim in late winter or early spring before new growth, removing dead or damaged stems. Pinching back stem tips in spring encourages fuller growth and more blooms. These fast growers can reach 10 feet tall in one summer, so cutting them back helps control their size. Always use clean, sharp tools like Fiskars loppers from Amazon.
- Fertilizing: As a heavy feeder, corkscrew vine benefits from regular fertilization throughout the growing season. Use a balanced water-soluble fertilizer monthly from late spring to early fall to support its growth and promote abundant blooms. A bloom booster fertilizer with high phosphorus content can also be beneficial; consider this bloom booster from Walmart.
