Garden Plans for Annual Vinca
Annual Vinca Characteristics
Annual vinca can be trailing or upright. Trailing vincas are a great option as a spiller out of a container or hanging basket. Upright varieties work well in mass plantings, especially in landscapes where you're looking to make a big impact with little maintenance.
Vinca flowers are suspended over glossy, emerald green foliage. Many cultivars are described as "with eye." These varieties feature one color in the center of the bloom that fades out to a main color. Flower colors can be pink, red, white, or purple.
Even though new varieties of annual vinca are small, the amount of blooms produced on one plant has nearly doubled. The smaller size of these new varieties also makes the plant easier to manage and great for container plantings.
Annual Vinca Care Must-Knows
Since annual vincas are native to Madagascar, they need the summer heat to thrive. Full sun is best, but they can take part shade if there's good air circulation. If an area is too stuffy, the plant can develop fungal problems. Vinca can also stand up to drought.
To start vinca from seed, sow and cover the seed with a light layer of soil. Keep the soil consistently moist during germination. Keep vincas out of cold areas; the plants will be slow to start without the heat they know and love. Vincas can also be started from cuttings but require high humidity and bottom heat to start.
It's important to note that the sap from vinca is poisonous. Interestingly enough, this plant produces compounds that kill cancer cells. Studies show that the discovery of these compounds has increased the likelihood of survival in leukemia patients.
