Vinca (Vinca minor) also called myrtle and common periwinkle, grows in U.S. Department of Agriculture plant hardiness zones 4 to 8. In these climates, it generally survives the winter. It's grown as an annual in colder regions, although vinca might survive under snow.
A lack of water also will cause vinca to wilt. The plant will wilt, you will water it, it springs back to life and then wilts again when it needs water. This can cause the plants to require more frequent watering or the soil in Read more
Symptoms develop quickly - especially during rainy weather. You may detect a brown, sunken lesion where the petioles are attached to the stems. When these spots develop, the stem collapses. If rains or overwatering continues, the fungus can spread to the base of the plant Read more
Fungal diseases, such as phtyophthora blight and leaf spot, are common among annual vinca plants. When soils are excessively wet, fungal spores are able to reproduce and infect plants. Infected plants first demonstrate signs of infection in the form of yellow to dark brown spots Read more
Vincas need acidic soil. Avoid planting earlier than May. Soil and nighttime temperatures need to be warm prior to planting.
Results: The results showed that use of cow manure vermicompost has a lot of potential for the development of landscape and house hold plants. Conclusion: In conclusion, cow manure vemicompost showed significant effect on plant growth both for the alfalfa and vinca rose.
Perennial vinca varieties have pinwheel-shaped springtime flowers in shades of lavender, purple, and white. Many offer outstanding variegated foliage that provides year-round interest (or nearly year-round in especially cold-winter areas). Vinca minor is hardy in Zones 4-8.
There are no edible uses listed for Vinca minor.
When taken by mouth: Periwinkle is UNSAFE. It can cause side effects such as nausea, vomiting, and other stomach and intestinal symptoms. It can also cause nerve, kidney, and liver damage. Large amounts can cause very low blood pressure.

Vinca needs little maintenance, and deadheading isn't required. They do well in full sun to part shade, and can tolerate some drought, although they flower best with regular watering. Check out the top 15 easy flowers anyone can grow.
Periwinkle (Vinca major and Vinca minor) is a mildly poisonous plant. Vinca has been used to treat high blood pressure and control excessive bleeding, but overdose results in hypotension (low blood pressure), which can cause collapse.
Vincas are fans of acidic soil, and their ideal soil pH level is around 5.5. Vincas survive droughts well but don't like wet soil, so give them a home in loamy or sandy soil that drains well. Space your plants 10 to 12 inches apart Read more
Vinca or Periwinkle will grow in range of light conditions, from full sun to shade. They will do well in average soils. They are both heat and drought tolerant. This makes Vinca ideal in hot, dry parts of the country where other flowers will wither Read more
Vinca is grown as an annual. It will often return in following summers from self-sown seed. Annual vinca is not the same as the perennial periwinkles (Vinca minor or V.
Soil that is excessively moist may cause a yellowing vinca plant. Vinca plants are no exception to this, as diseases like leaf spot and root rot are common. Caused by various types of fungal infections, yellowing vinca plants are one of the first symptoms of Read more
Vinca produces flowering vines that require warm temperatures and sunlight to remain healthy and productive. The plant grows as an outdoor annual in most climates, or you can keep it indoors as a houseplant in winter or year-round.
Annual vinca doesn't require deadheading, or the removal of faded flowers, to continue blooming, making it a wonderfully low-maintenance annual flower for sun.
Soil or potting mix must be well drained. To improve drainage, compost or sand can be incorporated into heavy soils. Vinca prefer soils with a pH of 5.5-6 but will tolerate high pH soils.
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 Read more
Vinca may normally curl up during hot, dry summer weather as part of an effort to conserve water. This should not be cause for alarm; the leaves will unfurl in the evening when temperatures drop and humidity increases.
Myrtle, Also Called Vinca or Periwinkle Spring and early fall are considered the best times to plant myrtle. It prospers in dappled sunlight but will also grow in full sun and even in dense shade. Use it instead of mulch under trees and shrubs to Read more
It is not necessary to pinch vinca plants, according to Colorado State University Cooperative Extension, because the plant branches off in all directions rather than just extending its length. It will not hurt this hardy plant. Although vinca does branch naturally, pinching may encourage bushier Read more
Annual vinca grows well in hot, sunny locations and blooms throughout the growing season. It can tolerate even relatively poor soils and dry conditions, but the National Garden Bureau recommends fertilizing once a month with water-soluble or granular fertilizer.
Even though its native environment is along river beds, Vinca is still a plant that can die due to too much water. Whenever drainage is poor, water sits and roots can't breathe. Fungus start developing, and ultimately they spread to the whole plant which dies.
