Runner beans are known for their vigorous growth and attractive flowers. The ‘Sunset’ runner bean stands out with its distinctive peachy-pink blossoms. This variety offers a dual benefit, serving as both an ornamental plant that enhances garden aesthetics and a productive source of edible beans. This combination makes it a favorite for gardeners seeking visual interest and fresh produce.
Characteristics of Sunset Runner Beans
The ‘Sunset’ runner bean (Phaseolus coccineus) is known for its robust vining habit. This plant produces striking flowers that range from soft pink to vibrant peachy-pink or even orange-red, adding a lively splash of color to garden spaces. These vigorous vines can extend significantly, often reaching lengths of 8 to 12 feet, and sometimes up to 20 feet, twining around any available support.
Beyond their visual appeal, ‘Sunset’ runner beans have a dual-purpose nature, functioning as both an eye-catching ornamental climber and a productive food crop. The species Phaseolus coccineus originated in the highlands of Mexico and Guatemala, where it has been cultivated for thousands of years. Its popularity has spread, cherished for its ease of growth and generous yields.
Growing Sunset Runner Beans
Cultivating ‘Sunset’ runner beans begins with proper site selection. These plants thrive in full sun, requiring at least six hours of direct sunlight daily to produce abundant flowers and pods. The ideal soil should be well-draining, loamy, and rich in organic matter. A soil pH between 6.0 and 6.5 supports healthy growth.
Planting should occur after all danger of frost has passed in late spring to early summer. Seeds can be directly sown into the garden at a depth of about 2 inches (5 cm). For optimal plant development and air circulation, space seeds roughly 6 inches (15 cm) apart. Alternatively, plant 3 to 4 inches (7-10 cm) apart at the base of supports and thin later to 6 to 9 inches (15-23 cm) within the row. If planting in rows, allow 18 to 24 inches (45-60 cm) between them.
These vigorous vines require sturdy support structures. Trellises, poles, A-frames, or wigwams made from canes approximately 8 feet (2.5 meters) tall are suitable. Consistent moisture is important, especially during dry periods and as they begin to flower and set pods. Water deeply and regularly to ensure the soil remains evenly moist but not waterlogged.
Runner beans are not heavy feeders if grown in soil enriched with organic matter. However, if your soil is less fertile or if you are growing them in containers, a high potassium liquid fertilizer, such as a tomato feed, can be applied once flowering begins. Avoid fertilizers high in nitrogen, as this can promote excessive foliage growth at the expense of pod production. Common challenges include aphids, slugs, and snails, which can be managed with organic prevention methods like good air circulation and physical barriers. Diseases like halo blight and rust are less common but can be mitigated by using clean seeds and removing affected plant parts.
Harvesting and Culinary Uses
Harvest ‘Sunset’ runner beans for best flavor and texture. For fresh consumption, pick the pods when they are young and tender, around 6 to 8 inches (15-20 cm) long, before the internal beans begin to swell significantly. Regular harvesting encourages the plant to continue producing more pods throughout the growing season.
To save dried beans, allow some pods to remain on the plant until they become papery and dry. The beans can then be shelled and stored for later use. Fresh, young pods are versatile in the kitchen, suitable for steaming, stir-frying, or adding raw to salads for a crisp texture.
Dried beans, after being soaked and thoroughly cooked, offer a creamy texture and nutty flavor, perfect for hearty soups and stews. Note that raw runner beans, like other beans, contain lectin and must be cooked thoroughly before consumption to neutralize this compound. The peachy-pink flowers are also edible and can be used as a decorative and flavorful garnish.
