Both of them belong to Ranunculaceae. Although they are both woody, fleshy and climbing, the shape and color of their roots are obviously different. First of all, the color is different. The root of Yellow Brown is clematis, while that of rotunda is reddish brown. Secondly, in shape, Clematis has long and thin roots with many fibrous roots, while rotunda has thick and short roots with few roots.
As a potted seedling of Clematis, customers can not directly see the bare root, so you can distinguish Clematis or not by observing the flowering characteristics.
Clematis has a large number of flowers, a long flowering period, and very bright colors, but also very rich. Compared with clematis, rotunda is very adaptable, commonly known as wild, and very cold resistant. It does not need too much care, and can also spend winter in cold outdoor. Its flower color is less than clematis, only white or yellow, and only one flower is opened on a vine, with a very small amount of flowers. So the rich color is the authentic Clematis
In addition to the root, flower color differences, the third method is to observe the flowering position of Lobelia and Clematis.
The flower of Clematis grows in the axil of the leaf, while the pedicel of Trollius is very straight and thick, and the flower grows on the top of the branch, usually a solitary flower. If you buy clematis, each leaf has flowers in the armpit, it is the authentic Clematis
In fact, we can also identify Clematis and Trollius by observing the morphological characteristics of the leaves. However, if this observation method is not senior iron powder, it is a relatively difficult observation method. We have mastered the above three methods, we can make a correct judgment on whether the genuine Clematis
