Madagascar Periwinkle, Titan Periwinkle, Titan Vinca, Vinca
Members of the Titan series have neat mounded habits, are large and heavy-flowering, and vigorous. The series is offered by Ball Horticultural Company and comes in a wide array of colors.
Vinca, or Madagascar periwinkle, is a tropical evergreen shrub that is grown as a tender annual or perennial in temperate climates. It is a highly heat and drought tolerant ornamental that blooms continuously and bears large, radial five-petaled blooms of red, pink, lilac, burgundy, magenta, purple or white throughout the growing season. Its glossy dark green foliage is dense and lush.
Vinca grows best in sites with full to partial sun and poor to fertile well-drained soil. This tough ornamental does well in hot, sunny beds and borders or sunny containers. Titan Series plants even excel in regions with only cool, mild summers. Madagascar periwinkle suffers in wet, heavy soils and will succumb to root rot with oppressive humidity and overwatering. It will reseed itself across the landscape, potentially being invasive in some warm regions with light soils.
