pear 'Black Worcester'


The 'Black Worcester' pear, a variety of the common pear, boasts striking features distinct to its cultivar. This plant is recognized for its fruit, which has a distinctive, almost round shape coupled with a rich, dark purplish-brown skin when ripe. The flesh inside is white, firm and quite dense, offering a sweet flavor with a hint of tartness, often described as rich and aromatic. It is important to note that the fruit's unusual color and historical significance make it quite a conversation piece in gardens where it is grown. The leaves of the 'Black Worcester' pear are distinctly broad and ovate with finely serrated margins, exuding a glossy, deep green hue that provides a lush backdrop for the fruit. The tree blooms with white flowers in clusters, known as corymbs, during the spring season. Each flower consists of five petals, which contribute to the ornamental value of the plant before the development of the notable fruit. These elements combined create an aesthetically pleasing appearance, with the dramatic contrast of the dark-hued fruit against the green foliage and white blossoms making this plant particularly attractive in a garden setting.

  • skullToxicity

    • To humans

      The plant in question is commonly known as Pear. The Pear tree, including the 'Black Worcester' variety, is not considered toxic to humans. All parts of the Pear tree that are commonly consumed, such as the fruit, are safe to eat when ripe. There are no well-documented toxic effects from ingesting the ripe fruit of Pear trees in humans. However, eating the seeds in large quantities is inadvisable as they contain amygdalin, a compound that can release cyanide in the digestive tract. Accidental ingestion of small amounts of seeds is generally not harmful due to the low concentration of amygdalin, but consuming large quantities of seeds could potentially lead to symptoms of cyanide poisoning, which include headache, dizziness, confusion, difficulty breathing, and seizures in severe cases.

    • To pets

      The Pear tree is also known by its common name, Pear. It is generally considered non-toxic to pets such as dogs and cats. The ripe fruit of Pear trees can be safely eaten by pets in moderation, although the seeds should be avoided. Similar to humans, the seeds contain amygdalin, which can lead to cyanide poisoning if ingested in large amounts. Signs of cyanide poisoning in pets may include vomiting, diarrhea, difficulty breathing, and potentially more severe symptoms such as seizures or collapse. It is always best to consult with a veterinarian if your pet consumes a large quantity of pear seeds or if there are any signs of illness following ingestion.

  • water dropWater

    The European pear or common pear, specifically the 'Black Worcester' variety, requires deep watering to ensure the root zone is thoroughly soaked. Young trees should be watered once a week with about 2 gallons per session. Mature trees usually need water every 10 to 14 days during dry periods, with increased amounts ranging up to 10 gallons depending on the size of the tree and the weather conditions. Avoid overwatering, as pears do not like standing water. It is optimal to water early in the morning to reduce evaporation and allow the foliage to dry during the day.

  • sunLight

    The 'Black Worcester' pear thrives in full sunlight for best growth and fruit production. Planting the tree in a spot that receives at least six hours of direct sunlight each day is ideal. Avoid locations with heavy shade or dappled light, as insufficient sunlight can lead to poor fruit yield and increased susceptibility to diseases.

  • thermometerTemperature

    'Black Worcester' pear trees are hardy and can tolerate a range of temperatures. They do well in areas where winter temperatures do not often drop below -20°F and summer temperatures average around 75°F to 85°F. The trees require a chilling period of cold temperatures to break dormancy and ensure healthy bud development, so a typical winter is beneficial for fruit set.

  • scissorsPruning

    Prune 'Black Worcester' pear trees to maintain their health, encourage fruit production, and shape the canopy. The best time for pruning is late winter or early spring before new growth starts. Thin out overcrowded branches and remove any damaged or diseased wood. Annual pruning helps to improve air circulation and light penetration into the canopy, which is essential for the development of quality fruit.

  • circleLife cycle

    Pyrus communis 'Black Worcester', commonly known as the 'Worcester Pearmain' apple, begins its life cycle with seed germination in the early spring. Following germination, it enters a juvenile phase, growing into a sapling with leaves and establishing a root system. As it matures, the tree enters the vegetative stage, where it develops strong branches and foliage. This is followed by the flowering stage, typically in late spring, where the 'Worcester Pearmain' produces white flowers that are pollinated by insects, leading to fruit development. The fruit ripens in late summer to early fall, and once ripe, the apples can be harvested. After fruiting, the tree enters a dormant phase during the winter to conserve energy for the next growing season.

      Early spring

    • Pyrus communis 'Black Worcester', commonly known as the 'Black Worcester' pear, is commonly propagated by grafting, which is the most popular method for this cultivar. This process involves taking a piece of a mature 'Black Worcester' pear tree, known as a scion, that contains buds and grafting it onto a rootstock of another pear variety. The best time to graft is in late winter or early spring when the trees are still dormant. Typically, a scion about 6 to 8 inches (15 to 20 cm) long is cut at an angle and joined to a similarly cut surface on the rootstock. The two pieces are then bound together, often with grafting tape or wax, to hold the joint secure until the scion has fully fused with the rootstock, a process that can take several weeks to months depending on environmental conditions. Grafting allows the 'Black Worcester' pear to benefit from the rootstock's hardiness and disease resistance while maintaining the desirable fruit characteristics of the 'Black Worcester' variety.
