Where does periwinkle grow best?
The periwinkle plant grows best in a partially shaded area in acidic soil; however, it can thrive in a variety of sunlight and soil conditions. Growing periwinkle in partial shade creates more vigorous growth. In many instances, extreme vigor may not be desirable unless the periwinkle plant needs to cover a large area.
Why do my periwinkles keep dying?
Even though its native environment is along river beds, Vinca is still a plant that can die due to too much water. Whenever drainage is poor, water sits and roots can't breathe. Fungus start developing, and ultimately they spread to the whole plant which dies.
Does periwinkle come back every year?
