Centrosema Virginianum
Known affectionately as the Spurred Butterfly Pea or Wild Blue Pea, this delicate perennial vine is a hidden gem of the American Southeast. It is celebrated for its ethereal, "upside-down" lavender blossoms that seem to float among the foliage. Often found weaving through tall grasses or scaling light fences, it adds a touch of whimsical elegance to wilder garden spaces.
The flowers of the Spurred Butterfly Pea are resupinate, which is a fancy botanical way of saying they are "inverted." During development, the flower stalk twists 180 degrees, placing the petal that is normally on the top (the banner) at the bottom to provide a perfect landing platform for heavy-bodied bumblebees!
To grow Centrosema Virginianum, also known as Spurred Butterfly Pea, you can follow these steps:


The recommended type of soil to use for Centrosema Virginianum plants is a well-draining soil mixture that is rich in organic matter. It is important to ensure that the soil pH falls within the range of 6.0 to 7.5, as this plant prefers slightly acidic to neutral soil conditions. The soil should be loamy to sandy in texture, allowing for proper drainage and root development. Avoid using heavy clay soils or compacted soils, as they tend to retain too much moisture and can lead to root rot. Additionally, it is beneficial to incorporate compost or well-rotted manure into the soil to further enhance its fertility and nutrient content.
