In graph theory, the blossom algorithm is an algorithm for constructing maximum matchings on graphs. The algorithm was developed by Jack Edmonds in 1961, [ 1 ] and published in 1965. [ 2 ] Given a general graph G = ( V , E ) , the algorithm finds a matching M such that each vertex in V is incident with at most one edge in M and | M | is maximized.
Cherry tree in bloom in Yachounomori Garden, Tatebayashi, Gunma, Japan, April 2009. The cherry blossom, or sakura, is the flower of trees in Prunus subgenus Cerasus. Sakura usually refers to flowers of ornamental cherry trees, such as cultivars of Prunus serrulata, not trees grown for their fruit [1]: 14–18 [2] (although these also have ...
Plum blossom. Descending from China and south east Asia, the earliest orange species moved westwards via the trade routes. [5] In 17th century Italy peach blossoms were made into a poultice for bruises, rashes, eczema, grazes and stings. [6] In ancient Greek medicine plum blossoms were used to treat bleeding gums, mouth ulcers and tighten loose ...
Leptospermum squarrosum, commonly known as the peach blossom tea-tree, [2] is an upright shrub of the family Myrtaceae and is endemic to central eastern New South Wales. It has thin, firm bark, broadly lance-shaped to elliptical leaves, relatively large white or pink flowers and fruit that remain on the plant when mature.
'Kanzan' is the most popular Japanese cherry tree cultivar for cherry blossom viewing in Europe and North America. Compared with Yoshino cherry, a representative Japanese cultivar, it is popular because it grows well even in cold regions, is small and easy to plant in the garden, and has large flowers and deep pink petals.
In the present day, ornamental cherry blossom trees are distributed and cultivated worldwide. [1] While flowering cherry trees were historically present in Europe, North America, and China, [2] the practice of cultivating ornamental cherry trees was centered in Japan, [3] and many of the cultivars planted worldwide, such as that of Prunus × yedoensis, [4] [5] have been developed from Japanese ...

A blossom tree (opening stems are in red, closing stems in blue) A blossom tree is constructed from a rooted tree embedded in the plane by adding opening and closing stems to vertices. The number of opening and closing stems must match. [2] Some authors require that blossom trees be rooted and put conditions on which kind of stems they can ...
