The sea of flowers has also become lively.

However, if you take it seriously, many people will be dominated by "facial blindness." referring to the rose, the rose is regarded as the rose, and the beauty of Yu is also alive as a "lying gun" and is recognized as a poppy.

Is it really hard to tell these "sister" flowers apart?

This time, the reporter will show you a good recognition.

Li Mei, Doctor of Flowers, Zhongshan Botanical Garden, Nanjing

It's all thorns!

Roses are not "romantic".

"the four seasons of the rose bloom, so it is also called 'moon red', but the rose is different. It only blossoms once in summer." Li Mei, a doctor of flowers in Zhongshan Botanical Garden, told reporters that under natural conditions, roses and roses "collide" in the summer season.

But how should they recognize them when they are in full bloom? Li Mei moves, first look at the leaves, "the leaves of the rose are broadly ovate to ovate-oblong, the edges are sharply serrated, both sides are nearly glabrous, and look shiny; the rose leaves are oval or long oval to Obovate, the edges are obtusely serrated, the surface is green, glabrous and glossy, and the veins are sunken and wrinkled." To put it simply, the leaves of roses look crumpled, but the leaves of roses look like moisturizers, which are much smoother than those of roses.

Looking at the thorns, "the characteristics of the two stem thorns are very distinct, the rose thorns are more, dense and pointed, and the thorns of the rose are short, thick, hooked prickles, relatively large, sparse and flat." Li Mei told reporters that the thorn of the rose belongs to the "strength school". If you want to pick it up, even if you are very careful, it is still possible to hurt your hand.

Then look at the flowers and fruits, Li Mei introduced that the flowers of the rose are larger, the petals are double to semidouble, the colors are varied, and the colors are varied, which can be described as colorful, and the fruit is round; the rose is small, the petals are double to semidouble, generally pink, purple and white, the fruit is flat, brick red, fleshy, smooth, and the sepals persist. "obviously, from the ornamental point of view, the rose is more valuable."

Finally, smell the flowers. The reporter found that the fragrance of rose flowers is relatively light, and the smell of roses is different and more full-bodied, which smells like a distinct "rose essential oil". In fact, compared to ornamental, indeed, the extraction of rose oil is the most important value of roses.

All poisonous?

You may have eaten poppy seed oil.

"Beauty Yu and poppy both belong to the poppy family, so they naturally look very similar, but in fact they are still very different." Li Mei said that during the observation, the main thing to see is that the whole plant of Yu Mei has obvious rough hair, many branches and slender branches, thin leaves, and a delicate feeling as a whole; the whole plant of opium poppy is smooth and "covered" with white powder, with stout stems, few branches, and thick leaves.

Of course, if you look carefully, the flowers are also different. Li Mei points out, "the Yumei flowers are smaller, the petals are extremely thin and tender, while the poppies are larger, and the petals are thicker and very shiny."

It is understood that when the poppy fruit is not yet ripe, the peel of the poppy will shed white milk. After drying, milk becomes a black gel, which is the source of many kinds of sedatives such as morphine, tibaine and codeine, and has a certain effect on the treatment of diseases, but at the same time, it is also rich in toxic alkaloids, which is a great harm to drugs and drug raw materials. Therefore, a certain amount of illegal cultivation of opium poppy will constitute the crime of illegal cultivation of original plants of drugs. Although the beauty of Yu is very similar to the poppy in appearance, she cannot make drugs, so she is a serious ornamental flower.

However, opium poppy is regarded as a poison, in fact, it is also very "aggrieved"-- because plants do not move, and when faced with the harm of bacteria, fungi, insects and large herbivores, they cannot escape and can only train themselves to become "poisonous masters". Defense through the synthesis of large amounts of toxic natural products, and alkaloids are one of the important weapons they use to defend against the outside world. Li Mei said, "many people think that opium poppy is poisonous all over the body. In fact, its seeds are not only non-toxic, but also rich in oil. Because of their special flavor, poppy seeds are also used to extract oil, or as seasoning after baking. Widely used in salads around the world."
