2. In addition, there are differences in leaves. The stipules on the petiole of Cymbidium hybridum are in the middle (half), while the stipules of Cymbidium hybridum are longer in two thirds.
3. The flowers of Cymbidium hybridum are pure white, and the flowers of Cymbidium hybridum are milky white or light yellow or yellow.

It should also be noted that Castanopsis kawakamii is different from Castanopsis kawakamii. Although there is a word difference, there is a big difference. Castanopsis kawakamii is a tall deciduous tree of Ficus of Moraceae, also known as Ficus bungeana, Ficus macrophylla, Ficus caudata and Ficus spp. Thick stems, tall trees and broad crowns. Eupatorium adenophorum is an evergreen tree of Michelia in Magnoliaceae.
The branches are tall and handsome, the leaves are green all year round, the yellow flowers are like blue fingers, and the long ivory petals surround the white style and are dotted among the green leaves. They are elegant and leisurely, and the flowers are quiet and sweet, especially when the buds are not in bloom. In the hot summer, Toona sinensis exudes fragrance, sitting by a tree or strolling in the shade. The air is filled with sweet fragrance, which gently curls and lingers for a long time, which is very comfortable.
Toona sinensis is not only used as landscaping and garden trees, but also made into potted plants and bonsai for indoor maintenance. Because of its evergreen seasons, beautiful plant shape and pleasant flowers, it is deeply loved by people. Let's briefly talk about the management and maintenance of Toona sinensis.
Eupatorium adenophorum is a typical southern tree. It likes loose, fertile and well-drained slightly acidic soil and is sensitive to soil pH. If it is watered with slightly alkaline water for a long time, it will cause poor plant growth and yellow leaves.
Eupatorium adenophorum is a positive tree species and is not tolerant to shade. If potted plants need to be placed in a sunny and south-facing position, they should be properly shaded in summer, and the temperature in winter should not be lower than 5℃. However, they should not be placed near the heating to avoid scalding.
Eupatorium odoratum likes humid environment, is not drought-resistant and waterlogged-resistant, and is relatively difficult to maintain. Therefore, in terms of soil configuration, loose and breathable humus soil should be mixed with sandy soil for cultivation, and water should be used to keep the soil moist without water accumulation. Water it thoroughly without watering it. Appropriate increase in watering frequency in summer, indoor management in winter, and slightly lower temperature, so as to reduce watering frequency and avoid waterlogging and root rot. If the leaves turn yellow or red, it is generally caused by excessive watering, so stop watering observation.
Perrin likes fertilizer. If the nutrients are insufficient, it is not easy to bloom, so bone meal, cake residue or animal hooves can be mixed into the soil as base fertilizer. In the growing season, alum fertilizer water and potassium dihydrogen phosphate should be used alternately for fertilization, usually once a week, and thin fertilizer should be applied frequently.
Perrin is prone to pests and diseases, so it is necessary to strengthen ventilation and prevent diseases, especially to prevent the harm of red spider. If you find that the leaves of plants are yellow and fall off, you must find out the reason. In addition to spraying pesticides, the basin should be moved to the shade, and watering should be controlled to avoid spreading.
