General Description

Flowering profusely, 'Titan Polka Dot’ has large bright white blooms with a tiny fuchsia eye and a neat mounding habit. Members of the Titan Series are offered by the Ball Horticultural Company and can easily be grown from seed.

Vinca, or Madagascar periwinkle, is a tropical evergreen shrub that is grown as a tender bedding plant in temperate climates. It is a highly heat and drought tolerant ornamental that blooms continuously and bears showy, radial, five-petaled white blooms 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 average, well-drained soil. Plant this tough ornamental in sunny beds and borders or containers, as well as seaside. Madagascar periwinkle dislikes "wet feet" and will suffer from root rot in poorly drained soils. It is known to reseed itself and in warm regions with light soils can become invasive.
