Oak tree flowers

Oak tree flowers

The English Oak is the dominant tree in most of Britain, particularly on the richer soils in valley bottoms. It has been planted everywhere in parks, gardens, deer parks and woods. It has male and female flowers on the same tree. Male flowers are on catkins and hang down, female flowers are small and red and located on short stalks called peduncles. Catkins release pollen in April and May and the red female flowers develop into acorns by autumn. The English oak acorns are on stalks but the closely related Sessile oak acorns have no stalks – they are sessile.

Manchurian Cherry

Manchurian Cherry

The Manchurian Cherry is native to north-east China, Siberia and Korea. It was introduced to Britain in 1910. It was ‘discovered’ by Richard Maack and registered in 1857. It has white flowers that resemble those of the Bird Cherry. It is valued for its beautiful bark, honey-brown when young and red-brown when older. It was rare but can now be found in urban areas and can be confused with other white flowered cherries in spring.

Note that a ‘single’ flower has 5 petals, a ‘semi-double’ flower has 2 rows of 5 petals and a ‘double’ has 3 or more rows. ‘Double’ flowers arise when some of the rows of anthers  become petals. The Wild Cherry cultivar ‘Plena’ has white ‘double’ flowers. Each flower has up to 30 petals.

Japanese Flowering Cherries are a large group of cultivars that were bred in Japan from the 15th Century and were known collectively as Sato Zakura (village cherries). Their taxonomic origin is unclear but one of their parents is believed to be the Japanese Cherry (Prunus serrulata), native to northern and central China, Korea and Japan. The flowering cherries were introduced to Britain as early as 1822. They bear white or pink flowers in spring. There are more than 20 cultivars on sale in Britain. Some examples are shown here.

‘Kanzan’ has pink ‘double’ flowers in spring before the leaves. Each flower has 25 to 28 petals.
