There are 12 different metal money of periwinkle , but when people bring up to Cape periwinkle as a groundcover , they are unremarkably talking about two specific species : Vinca modest and Vinca major . These two species are popular choices for groundcovers due to their power to circulate and take shape heavy mats of foliage .
One distinguishing feature of winkle is its diametrical leaves . This means that the leave are arranged in pairs along the stem , with each pair straightaway across from the other . The leaves are typically glossy and dark green in color , providing an attractive backdrop to the blossom .
verbalize of flower , periwinkle plants produce single efflorescence that add up in various shades of blue , purple , and white . The flowers are by and large small in size but are produced in abundance , creating a stunning display when in efflorescence .
It ’s of import to mention that the perennial periwinkle should not be confuse with the bedding plant known as Madagascar winkle ( genus Catharanthus roseus ) . While they share a similar name , these two plants are actually unlike coinage . Madagascar periwinkle is an annual plant that is often grow as an ornamental in garden due to its colorful flowers .

In my own experience as a gardener , I have found periwinkle to be a reliable and low - criminal maintenance groundcover option . It is tolerant of a wide reach of soil conditions and can thrive in both sun and ghost . Once established , it spreads quickly and can help to suppress weeds in the garden .
When planting periwinkle as a ground cover , it ’s crucial to prepare the territory by removing any skunk or grass and add organic thing to improve fertility . The plants should be spaced about 12 inches apart to provide for adequate spreading . Regular watering during the establishment period is authoritative , but once the plant are established , they are quite drought - broad .
One matter to keep in mind when growing periwinkle is its ability to propagate aggressively . While this can be an advantage in terms of groundcover , it can also become invasive in sure areas . To prevent this , regular upkeep such as trimming back the plants and transfer any runners that have jeopardize into unwanted areas is necessary .
Vinca and periwinkle are two name used to describe the same industrial plant . It is a versatile groundcover option with glossy leaves and abundant efflorescence . However , it should not be confused with Madagascar old maid , which is a dissimilar metal money altogether . When decently managed , perennial periwinkle can be a beautiful accession to any garden or landscape .
