I have displayed two of my Vinca findings, one of which is clustered amongst a boarder-like hedge. The second being of a ground covering nature within a planting bed. From observation, it seems that the plant, which is located amongst the hedge, has self seeded, meaning that its presence was un-intentional. However, the Vinca coverage seems to have been planted with intent to achieve a dense, and boundary-like edge to the curving pathway. The shear span of its coverage also indicates that this Vinca was planted intentionally, as additional space surrounding its initial plant location was provided in order for it to expand and cover a wider area. Because of the mass of space given for it to dominate, the plant will continue to excel in health, as it has no opposition to share nutrients with. Its low growing tendencies are beneficial for this location as it allows views across the park and remains un-challenged when in inclement weather. Due to the large tree in close proximity, a high growing plant will have struggled for sunlight, which would have been prevented by the tree canopy above. It also brings a deep-green colour palette to the area with petite, purple flower; adding to the surrounding 'subtle' colour palette.
