Yellow warblers are generally used as a companion flower, and can be paired with roses, lilies and carnations.
The most common is with roses, which symbolize love, to represent "the beginning of a beautiful love".
It is native to North America and was first introduced as a garden flower in Shanghai and Nanjing, China, and then escaped into the wild, leading to the demise of native plant species, seriously affecting the original vegetation and destroying biodiversity.
Canadian yellow flower belongs to Asteraceae, commonly known as "yellow warbler".
The plant is 200 centimeters tall.
Evergreen shrub, plant height for the middle, with prickles, medium density, the number of leaflets 3-7, leaf color light green to dense green, flower stem length of 60-80cm, flower buds for the ovate, flower color is pure yellow, flower shape for the high heart of the warped angle, the diameter of the buds for the 2-3cm, fully open flowers up to 9-11cm in diameter, the height of the flower is about 4-5cm, the flower is heavy for the broad petals, petal number 40-50 pieces, belongs to the middle flower type varieties.
The flower shape is star-shaped when viewed from above.
Specificity: the color of the mother plant "Dream" is red and yellow; the color of the mutant plant "Yellow Warbler" is pure yellow.
Consistency: Among the 80 variant plants obtained so far, all of them are pure yellow in color, achieving consistency.
Stability: In the more than 80 plants obtained after 2 years of repeated cuttings propagation, there was no phenomenon of the color returning to the mother plant's color in cultivation, and all of them maintained the pure yellow color of the variegated color, which indicates that the specificity of the variety has been stabilized.
"Canada's one branch of the yellow flower" plant stout, average height of nearly 2 meters, in the process of growth, will compete with other species for nutrients, water and space, so that the green shrubs died in pieces, at the same time, it will also eat cotton fields, corn fields, soybean fields, etc., affecting the yield and quality of these crops, resulting in direct and indirect economic losses, on the crop. indirect economic losses to the crops.
Canadian monocot can be hybridized with species of the same genus of near-origin, or even species of different genera, which may lead to genetic erosion of native species.
