Cornwall with pink America flowers, Cornus Florida Rubra |

Cornus Florida , the Cornwall with flowers , is a species of tree flowers of the family of c ornaceae Originally from the east of North America and northern Mexico . An endemic population once extended from the southern coast of Maine north of Florida ^[4] and west to the Mississippi river. The tree is commonly planted as an ornamental plant in residential and public areas because of its Bracts.

sighted and its interesting bark structure. 2 Seeds 

Cold stratification 4 months before sowing, ideal temperature of sowing 18/20 ° C The flowery dogwood is a small tree with leafs deciduous reaching 10 m (33 ft) high, often wider than high at maturity, with a trunk diameter going up to 30 cm (1 Pi). A 10 -year tree will measure approximately 5 m (16 ft) high. The Leaves are opposite, simple, oval, 6–13 cm (2.4–5.1 in long and 4–6 cm (1.6–2.4 in) Large, with an apparently whole margin (in fact very finely toothed, under a lens).

They shoot a rich red-brown in the fall. The flowery stallow reaches its largest size and its growth potential in the high-south, sometimes up to 40 feet high. At the northern end of its distribution area, heights of 30 to 33 feet are more typical.

A warm and humid summer is necessary for the new shoots to get started in the fall. The maximum lifespan of C. Florida [A1111] is around 80 years.  ^[5]

The flowers are individually small, discreet and hermaphrodites, with four greenish yellow petals (no bracts) of 4 mm (0.16 in) long. About 20 flowers are produced in an inflorescence dense, rounded, in the form of umbelle , or capitule, from 1 to 2 cm (0.39 to 0.79 ) of diameter. The Capitula is surrounded by four large white, pink or red bracts clearly visible (no petals), each bracts measuring 3 cm (1.2 in) long and 2.5 cm (0 , 98 in) wide, rounded and often with a distinct notch with apex .

When they are in the wild, they can usually be found at the edge of the forest and often on dry ridges. While most wild trees have white bracts, some cultivars selected from this tree also have pink bracts, some even almost a real red. They generally flourish from early April in the southern part of their distribution area, until the end of April or early May in the northern and high altitude regions. Le Cornouiller Kousa similar ( Cornus Kousa ), originally from Asia , flowers about a month later.

The fruit is a group of two to ten DRUPES distinct (merged into Cornus Kousa ), each from 10 to 15 mm (0.39 to 0.59 PO) long and about 8 mm (0.31 in) wide, which mature at the end of the summer and at the beginning fall to a bright red, or sometimes yellow with a pink blush. They constitute an important source of food for dozens of species of birds , which then distribute the seeds . They are also a larval host plant for several varieties of nocturnal butterflies, notably EUDEILINIA Herminiata , The thyatiride of Cornwall , AntispiLaiella , the ringworm of the ringworm Spicy rose , The ringworm of Grandes Arches , ^[6]The Pyral of Pécan, ^[7] The Cornwall Pyral , ^[8] The Tordeuse Rosacea , the Towigen of the Crucifers , Les Azurs Printiers ,
