(Vinca minor )
Priority: - Control
Identification and Reproduction
- Periwinkle is an evergreen groundcover commonly planted as an ornamental.
- Leaves are dark green and glossy and arranged oppositely. In certain growing conditions leaves may be varigated.
- Their vines can reach around 15 cm tall and spread two metres in length.
- During late spring and early summer periwinkle will produce blue to purple or even white flowers. They will be composed of 5 distinct petals.
- Periwinkle reproduces vegetatively from rhizomes but also through cross-pollination.
- It is possible to grow by seed, but it will reproduce very slowly.
Habitat & Ecology
- Found throughout the Lower Mainland of BC.
- Typically growing in wet, forested areas in dense mats.
- Periwinkle perfers areas with nutritious and moist soil in partial shade.
- Grows very rapidly and aggresively.
- Often escapes ornamental gardens and spreads to forested areas.
- Displaces native species.
- As a ground cover it negatively impacts native conifer seedlings by taking up space and resources.
- Since periwinkle has shallow roots it is easy to hand-pull the plant.
- Removal is best in small infestations and when soil is damp and loose.
- Ensure that there is minimal root fragmentation as they can resprout.
- If the infestaion covers a larger area it may be effective to use solarization; covering the area with a tarp or plastic covering. Leave for a minimum of 4 months to smother the plants.
