Guide to Cultivating Periwinkle, Scientifically Known as Vinca Minor
Periwinkle, a popular groundcover, is known for its ability to thrive in shady conditions and spread rapidly. This makes it an ideal choice for many gardeners seeking a low-maintenance option. However, it's essential to be aware that periwinkle is invasive in several states, so it's crucial to check with your local extension offices before planting.
This hardy plant forms a dense cover, adding a touch of elegance to your garden. To keep it tidy, regular weeding is necessary. To help contain periwinkle, plant it in areas bounded by concrete, walls, or turf grass.
There are various cultivars of common periwinkle, each with unique characteristics. For instance, '24 Carat' boasts golden leaves, while 'Alba' offers white flowers. 'Alboplena' displays double white flowers, 'Flore Pleno' showcases double purple flowers, 'Variegata' features yellow variegation, and 'Honeydew' offers chartreuse foliage.
Despite its rapid growth, periwinkle does not require pruning. However, trimming it back every couple of years can make it look less weedy and leggy. It's worth noting that there is no specific information about a periwinkle variety with yellow-colored leaves in young growth.
Unfortunately, periwinkle is susceptible to stem cankers, which are caused by fungal infections. These appear as sunken lesions on the ground. To prevent stem cankers, avoid overhead watering and overwatering, and remove damaged vinca stems as you see cankers.
Mary Ellen Ellis, a renowned gardening expert with degrees in Chemistry and Biology, specialises in flowers, native plants, and herbs. She emphasises the importance of planting periwinkle responsibly, avoiding natural areas such as meadows or woodlands.
By understanding its characteristics and potential drawbacks, you can make an informed decision about whether periwinkle is the right choice for your garden. Whether you're looking to cover a small area quickly or add a touch of colour to your shady spots, periwinkle could be the solution you've been seeking.
