Which vincas are perennials?
Perennial Vinca Varieties The two main species of perennial vinca are: Vinca major: Less cold hardy, more tolerant of heat, has broader, hairier leaves, and larger flowers than Vinca minor. Annual vinca has durable, abundant flowers from May to frost. Many new cultivars are available in a wonderful selection of colors and larger flowers, with growth habits ranging from upright, dwarf, and creeping.Vinca minor is a perennial, meaning it will return year after year with minimal care. Once established, it forms a dense, mat-like ground cover that spreads by sending out trailing stems that root at intervals along the soil surface. As a result, it can steadily expand its coverage each season.Climate: Vinca is generally hardy in USDA Hardiness Zones 4-9. Some cultivars may be more cold-tolerant, while others may be more heat-tolerant. In colder climates, it may die back to the ground in winter, but it will usually regrow from the roots in spring.Use it en masse in beds and borders or tuck it into mixed containers with other annual flowers.

And vinca are prone to at least three wet-soil-related fungal diseases – phytophthora, botrytis and rhizoctonia. They can also get aster yellows, which is manifested by the same kind of yellowing leaves that result from rotting in soggy soil and from cold weather.Temperature and Humidity Annual vincas prefer to be grown in a very warm environment and this is why many growers have difficulty with them. Daytime temperatures should be around 82˚F (±2˚F), and at night, around 68˚F (±1˚F). Temperatures below 64˚F can stunt plant growth and cause leaves to turn yellow.
