Blue Pea Vine
The Blue Pea Vine, also known as the Butterfly Pea or Clitoria ternatea, is an exceptionally beautiful and easy-to-grow flowering vine that is grown for both its flowers and its dramatic foliage. It is native to parts of Southern Asia, especially India, and it is a perennial plant which produces elegant, deep-blue flowers. It is often trellised or fence grown for the purpose of providing attractive outlines and screening. The flowers have a deep and rich blue which is closest to Royal Blue when it is fresh and the foliage is large and glossy green and in threads that spiral tightly around each other
The Blue Pea Vine needs regular and consistent watering. Once established, it can withstand the heat and the drought. It is recommended to keep the soil evenly moist, but not overly wet, and avoid letting the soil dry out to allow the foliage to remain vibrantly green. During the winter months, the plant will need less water, however, water more during the spring and summer months.
Blue Pea Vine requires lots of sunlight for best growth and flowering. This plant is best suited for areas that get 6 or more hours of direct sunlight per day with the ideal temperature ranging between 65-85°F (18-29°C). Too much shade will reduce flowering and the foliage may become lanky and tangled.
Blue Pea Vine prefers warm temperatures but can tolerate cooler temperatures. An ideal temperature range for nursery-grown plants is between 60-70°F (15-21°C), with temperatures in the high 70s and low 80s F (26-27°C). Temperatures above 90°F (32°C) will cause the foliage to turn yellow or brown.
This plant prefers to be in a relatively humid environment, ideally with levels at around 40-50%. Since it is a tropical plant, irrigation and/or a humidifier should be used during hot summer months to simulate a tropical environment.
Blue Pea Vine prefers a light and well-draining soil that is rich in organic matter. A combination of compost and perlite or peat moss is a good choice. Do not use heavy, clay-based soils as this can increase the risk of root rot. A neutral or slightly acidic soil pH in the range of 6.0 to 7.2 is also recommended.
The Blue Pea Vine should be fertilized regularly in order to promote healthy growth and abundant flowering. A balanced fertilizer with micronutrients such as iron, zinc, and manganese is recommended. Fertilize every two weeks during the active growing season using an all-purpose liquid fertilizer at half strength. During the winter months, fertilization should be reduced or eliminated altogether.
Blue Pea Vine is more susceptible to certain pests than other plants, such as aphids, mites, mealybugs, and whiteflies. Natural predators such as lacewings, lady bugs, and beneficial nematodes can be used to help control pest populations. The use of neem oil can also be helpful in repelling pests. However, it is important to be aware that neem oil is a natural insecticide/fungicide and should be used sparingly. If all else fails, chemical pesticides can be used, but should be used as a last resort.
Blue Pea Vine should typically be repotted every two years in the early spring, using a potting mixture rich in organic matter. When repotting, be sure to use a container that is not too large as the plant can become root bound in a container that is too large. Repotting should be done with care to avoid damaging the fragile root system.
Blue Pea Vine is a vining plant that requires regular pruning. Pruning will keep the plants in a compact upright shape and can help promote more vigorous flowering. Pruning should be done in spring, after flowering and in late summer, before flowering. Pruning should be done to shape the plant and remove any dead or diseased branches.
Mulching around the Blue Pea Vine is beneficial as it helps retain moisture and prevents weeds from competing with the plant’s nutrients and space. A thick layer of organic mulch, such as pine needles or grass clippings, will do the job nicely.
Propagation of the Blue Pea Vine is usually done through seeds, although vegetative propagation of cuttings is also possible. When planting from seed, the seeds should be soaked for 6-8 hours prior to planting, as this helps to soften the seed coat and encourage germination. The seeds should be planted in a sterile, well-draining seed starting mix.
Blue Pea Vine is a vining plant, so it needs support to remain upright and encourage vigorous flowering. A trellis or fence is the best choice for support. If it is grown in a container, it is best to add a support structure to avoid the weight of the foliage causing the container to tip.
Although the Blue Pea Vine is a perennial plant and can live for up to 5 years, it will need a period of rest in order to remain healthy. During this time, the plant should be placed in a room that receives indirect sunlight and the growing medium should be kept slightly moist. This rest period should last for about 3-4 months.
The Blue Pea Vine is safe for pets as it does not contain any toxic parts. However, the leaves are somewhat uncomfortable to chew on due to their thick, leathery texture.
