The difference between big-leaf cold orchid and fine-leaf cold orchid (picture and text)

Generally speaking, cold orchid refers to winter flowering winter cold orchid, its florescence is mostly concentrated in mid-late October to December, of course, there are earlier and later, has been very few, in winter cold orchid, according to its different characteristics are divided into big-leaf cold orchid and fine-leaf cold orchid, let's talk about the difference between big-leaf cold orchid and fine-leaf cold orchid.

Big-leaf cold orchid and fine-leaf cold orchid are not distinguished by the length and width of the leaves (that is to say, there are also small leaves in the big leaves, tall plants can also appear in the fine leaves), but by whether the petals (especially the holding petals) have a covering wheel, whether the background color of the tongue petal is white, and whether the orchid root is stout or not. There is no mid-leaf in Han Lan (Mid-leaf Han Lan). When we describe the leaf information of a cold orchid variety, it is best to describe it more clearly, such as large-leaf and thin-leaf cold orchid, big-leaf middle-leaf cold orchid or big-leaf cold orchid. In this way, even those who do not fully understand cold orchids will know that they are describing big-leaf cold orchids. Similarly, when describing the fine leaf cold orchid, we can also use the fine leaf type cold orchid, the fine leaf middle leaf type cold orchid and the fine leaf large leaf type cold orchid to distinguish the leaf size.

Big leaf cold orchid, as the name implies, the leaf (plant type) is relatively tall, but there are also a considerable part of the leaf type is relatively short, the leaf color is lighter, the leaf surface is bright, and the root is relatively thin. The leaves (plant type) of Cymbidium are relatively short, and some of them are relatively tall, with darker leaves, larger glossiness, more thick roots, and a very small number of fine roots.

Most of the petals (especially the holding petals) of Cymbidium have a covering wheel, and most of them have a white wheel, and a few of them are red (or purplish red) and yellow. However, there are very few fine leaves without any covering wheels, and this part mainly appears in natural hybrid varieties; the background color of the tongue flap of fine leaves is almost all white, and a considerable number of them are covered with green tendons on a white background, and there are not many on a pure white background; of course, some tongue flaps are also mixed color background, very few. Relatively speaking, the petals of Magnolia have few or no capping wheels; similarly, the tongue petals of Magnolia have a white background, but there are also some, and the background color of the tongue petals of the big leaves are more mixed (there are also solid tongue petals in the big leaf cold orchids, such as green and yellow tongues). The big leaf cold orchid's tongue valve all has the tongue coating (villus), the fine leaf almost does not have.

Big leaf cold orchid no matter is the flower color, or the tongue petal background color is relatively rich, relatively speaking, the fine leaf is single. Blue and white flowers are more common in fine-leaf cold orchids, while safflower, purple, white and yellow flowers are relatively few. There is a kind of color-changing flower in the fine-leaf cold orchid, which usually begins to change color when the bud is about to blossom, and some varieties change color very brightly.

Relatively speaking, the big leaf cold orchid has more flowers, more than a dozen, the flower rod is stout, the flower arrow comes out of the shelf accounts for the majority; the petal of the big leaf is relatively slender, so the flower pattern of the big leaf is different, or regular, or elegant, or twisted, the image is numerous. The fine-leaf cold orchid has fewer flowers, usually three or five, and more than seven or eight, and the flower rod is thinner, that is, the so-called wick pole, the flower arrow of the fine-leaf cold orchid can not come out of the shelf; the petals of the fine leaves are shorter, the outer petals are more bony, and the flowers bloom with larger leaves. From this point of view, I think: big leaves are suitable for clump planting (that is, many seedlings are cultivated together, do not divide them too thin, except those who pursue varieties to grow seedlings), so that not only the plant type looks majestic, but also at the flowering stage, the flower stalk high out of the shelf shows its majestic nature. On the contrary, fine leaves are suitable for single planting (less seedling cultivation), which not only solves the problem of seedling development of fine leaves, but also highlights the weak beauty of fine leaves, and will not be crowded to flower petals because of the large number of leaves at flowering stage. in this way, even if the fine leaves are not out of the shelf, the appreciation of flowers will be clear, simple and clear at a glance.

The florescence of the big leaf cold orchid is mostly concentrated from late October to November every year, and the fine leaves are usually from November to December. According to the climate differences in different places, some of them are advanced or delayed, but not too far away. Of course, the florescence span of Han Lan is very wide, which is very rare. The flowers of the big leaf cold orchid are fragrant, the fine leaves are fragrant, and the fine leaves are very few; no matter the large leaves, the fine leaves also have an unfragrant existence, which is also very few. Due to the temperature, the fragrance of cold orchid flowers can not be emitted. According to my experience, the big leaf cold orchid is higher than 20 degrees, the fine leaf cold orchid is higher than 10 degrees, it is generally difficult to smell the fragrance, of course, there are individual high temperatures also put fragrance. Fine-leaf cold orchids can only smell fragrance when it is close to zero, so many orchids who grow orchids in the north can not smell the fragrance of fine leaves (when the fine leaves bloom in the north, the room is basically sending heat), as long as the fragrance conditions are suitable, both large leaves and fine leaves can put fragrance. The fine-leaf cold orchid blossoms frequently, most of the one or two seedlings can blossom, and the big-leaf cold orchid blossoms much lazily.
