Phacelia plants are perfect for luring in all sorts of beneficial insects, such as butterflies and bumblebees. They can be planted as a border plant, or in the corners of your garden where they grow to a mature height of roughly 20 inches tall. They typically come in shades of blue, violet and pink.
Phacelia is categorized as an annual flowering plant, which means that they will grow quickly, producing many flowers through the Summer season. They eventually wilt with the cooler temperatures of the Autumn season.
