Vinca is an easy-to-grow summer annual for beds, borders, edging, and containers. It prefers full sun, tolerates heat and drought, and can be relied on to flower in the hottest weather throughout the entire summer.

Improper pH may increase disease problems with vinca. It grows best in well-drained organic soils with a pH of 5.5 to 6.0 but will tolerate higher pH levels.

The spent flowers do not require deadheading to encourage more blooms or pinching to maintain a tidy growth habit.
