Bidens aristosa and Bidens polylepis are two species of plant that go to the same genus , Bidens . While they share some similarity , there are distinct dispute between them that can help you identify and differentiate the two .
One noticeable difference is in the appearance of the leaf - like parts straightaway under the flower heads . In Bidens aristosa , these parts may or may not have hirsute edge . This mean that some specimen of this species may have smooth edge on these foliage - like structures , while others may have a slight blurriness or hairs along the bound . On the other hand , in Bidens polylepis , the folio - alike parts under the flower head have coarsely hairy edges . This means that the border of these structure are distinctly hirsute , give the plant a unlike grain and appearance compared to B. aristosa .
Another difference lie in the grain of the peak stem . In B. aristosa , the flower stem is downlike , have in mind it has a fine bed of soft , myopic hairs . This can give the prow a slightly fuzzy or velvety appearance when observed up tight . On the other manus , in B. polylepis , the flower bow is also pubescent , but the grain and density of the hairs may dissent slightly from that of B. aristosa . It is important to take note that the downiness of the bloom stem can depart among private plant within each metal money , so it is not always a reliable tell apart feature .
In term of finish and charge , both B. aristosa and B. polylepis are generally easy to uprise and maintain . They are typically intrepid plants that can tolerate a broad range of soil conditions and are comparatively drouth - tolerant once established . They also both prefer full sun to partial subtlety and can be grown in various types of gardens , including flower beds , borders , or containers .
Personally , I have had the opportunity to operate with both B. aristosa and B. polylepis in different landscape gardening projects . I retrieve that the differences in the show of the leaf - like part and the texture of the flush stem were the most dependable feature to identify and severalize the two species . By closely analyse these characteristic , it becomes leisurely to distinguish between B. aristosa and B. polylepis in garden scope .
While both Bidens aristosa and Bidens polylepis are similar in many ways , such as their ease of polish and druthers for similar growing conditions , there are trenchant difference in the show of the leaf - corresponding parts under the flower nous and the grain of the flower stem . By compensate attention to these details , nurseryman and landscapers can accurately name and differentiate between the two species in their garden .
