Teinturier grape


The grapevine known as 'Purpurea' is admired primarily for its distinctive colored foliage. The leaves of this plant take on a range of hues throughout the growing season, starting with a bright green in spring. As they mature, the leaves become tinged with a deep purple to reddish-purple hue, which intensifies as the weather grows cooler. This rich coloring makes it a standout choice for adding a touch of dramatic color to the landscape. The grapevine also bears clusters of grapes that can vary in color, but typically, they are not the primary focus when this plant is used for ornamental purposes. The grapes are small and may be used to make wine or simply enjoyed as a natural decoration that complements the foliage. The stems of the vine also echo the color scheme, with a reddish-purple tinge that adds to the overall visual appeal. This variety, with its vibrant leaves and decorative fruit clusters, provides a striking visual display in gardens and on trellises.

  • water dropWater

    The Purple-leaf Grape should be watered regularly during its growth season, but it's important to let the soil dry out slightly between waterings. Generally, deep watering once every week with approximately 1-2 gallons per plant is recommended, adjusting as needed for rainfall and temperature. During hot, dry spells, they may need more frequent watering, but it is crucial to avoid waterlogged soil to prevent root rot. In winter, watering can be reduced significantly as the plant is dormant, providing enough to keep the roots from drying out, which may be as little as once a month depending on climate conditions.

  • sunLight

    Purple-leaf Grape vines thrive in full sun, which means at least 6-8 hours of direct sunlight per day. They perform best and produce the healthiest growth and fruiting when planted in a location that receives unobstructed sunlight throughout the day. Partial shade can be tolerated, but the intensity of leaf color and fruit production may be lessened.

  • thermometerTemperature

    The Purple-leaf Grape prefers a temperate climate and grows best in temperatures between 50°F and 85°F. It can withstand winter chill down to around 20°F, but frost can damage young leaves and shoots. Summertime heat above 90°F may stress the plant, so providing some shade or water to cool it down during extreme heat is beneficial.

  • scissorsPruning

    Pruning is essential for the health and productivity of Purple-leaf Grape vines. Prune in late winter when the plant is dormant, removing dead or overcrowded wood and shaping the plant. This encourages better air circulation, sunlight penetration, and can improve fruit quality. Annual pruning also helps control the plant's size and encourages the growth of new, fruitful vines.

  • bambooSoil

    The best soil mix for the Purple-leaf Grape is one that is deep, fertile, and well-draining with a slightly acidic to neutral pH, ideally ranging between 5.5 and 7.0. A mixture of loam, compost, and perlite or sand will encourage healthy growth and support the vine's root system.

  • plantRepotting

    Purple-leaf Grape vines are vigorous growers but are commonly planted directly in the ground. In a pot, young plants may require repotting every 2-3 years to accommodate root growth. Mature vines, if containerized, should be repotted as needed, which may be less frequent.

  • circleLife cycle

    The common name for Vitis vinifera 'Purpurea' is Red-leaf grape. In its life cycle, the Red-leaf grape starts as a seed, which germinates in the soil when conditions are warm and moist, producing a young vine. As the vine matures, it develops a robust root system and woody trunk, along with climbing tendrils, which allow it to support itself on structures or other plants. The plant enters a period of vegetative growth, sprouting large, lobed leaves that can have a purple-red hue, hence the name 'Purpurea'. Following this, it produces inflorescences that bloom and are subsequently pollinated, leading to the development of grape clusters. The Red-leaf grape completes its life cycle by ripening its fruit, which can be harvested and, if conditions such as temperature and humidity are right, the seeds within the grapes can again germinate and give rise to new vines.

      Spring-Early Summer

    • The Vitis vinifera 'Purpurea', commonly known as Purple-leaf Grape, is often propagated by hardwood cuttings. This method is particularly popular because it is relatively easy and cost-effective. Cuttings are typically taken during the plant's dormant season, which falls in late winter or early spring. Healthy, mature canes from the previous year's growth are selected and cut into lengths of 12 to 18 inches (about 30 to 45 centimeters), each with several buds. The bottom end of the cutting is dipped in rooting hormone to encourage root development and then planted in well-draining soil. The cutting should be placed with about two-thirds of its length buried in the soil to ensure that it has enough depth to develop a strong root system. Adequate moisture and protection from extreme temperatures are essential until the new plants are well established.
