Berberis thunbergii, the Japanese barberry, Thunberg's barberry, or red barberry, [1] is a species of flowering plant in the barberry family Berberidaceae, native to Japan and eastern Asia, though widely naturalized in China and North America, where it has become a problematic invasive in many places, leading to declines in species diversity, increased tick habitat, and soil changes.
The genus Berberis has dimorphic shoots: long shoots which form the structure of the plant, and short shoots only 1–2 mm (0.039–0.079 in) long. The leaves on long shoots are non-photosynthetic, developed into one to three or more spines [5]: 96 3–30 mm (0.12–1.18 in) long.
Renewal pruning. Spur pruning: Spur bearing varieties form spurs naturally, but spur growth can also be induced. Renewal pruning: This also depends on the tendency of many apple and pear trees to form flower buds on unpruned two-year-old laterals. It is a technique best used for the strong laterals on the outer part of the tree where there is ...
Pruning is a horticultural, arboricultural, and silvicultural practice involving the selective removal of certain parts of a plant, such as branches, buds, or roots. The practice entails the targeted removal of diseased , damaged, dead, non-productive, structurally unsound, or otherwise unwanted plant material from crop and landscape plants .
Berberis vulgaris, also known as common barberry, [3] European barberry or simply barberry, is a shrub in the genus Berberis native to the Old World. It produces edible but sharply acidic berries, which people in many countries eat as a tart and refreshing fruit.
The APG IV system of 2016 recognises the family and places it in the order Ranunculales in the clade eudicots. [2]In some older treatments of the family, Berberidaceae only included four genera (Berberis, Epimedium, Mahonia, Vancouveria), with the other genera treated in separate families, Leonticaceae (Bongardia, Caulophyllum, Gymnospermium, Leontice), Nandinaceae (Nandina), and ...
Disagreeing with this, Kurt Polycarp Joachim Sprengel classified it in Berberis as Berberis japonica in 1825. [1] A paper was published by Joseph Edward Laferrière in 1997 summarized the arguments for Mahonia being more properly classified as a synonym of Berberis. [9] As of 2023 this is the most common classification by botanists. [1]
