Vinca, Myrtle, Periwinkle—Vinca or Catharanthus
roseus
Family Apocynaceae
Plant Identification
Vincas are perennials usually treated as annuals.
Plants grow well as ground covers or in hanging baskets. Leaves
are long and glossy. Flowers appear in spring and vary in
color. They may be white or white with a rose center, bluish
pink, lavender, or bright pink. Flowers bloom throughout the
summer.
Some species of Vinca, such as Vinca
major,
are invasive weeds. Other species may be better choices when
planting.
Optimum conditions for growth
Vincas grow well in full sun or partial shade. They
thrive in dry or humid heat and need little to moderate amounts
of water. Do not overwater and make sure plants are growing
in well-drained soil.
