What are the differences between Plumbago auriculata and Plumbago prunifolia? We explain how to distinguish between similar species! Are there two types of stamen length? Only insects with long mouths can suck nectar from the flowers!?

Plumbago (Plumbago auriculata) and Plumbago rhododendron are two horticultural varieties of the Plumbaginaceae family that produce somewhat unusual blue flowers. In Japan, they are cultivated in gardens for ornamental purposes, and are easily confused due to their similar names, blue flowers, and similar flower shapes. However, their classification is based on their genus level...

What are the differences between Trachelospermum asiaticum, Trachelospermum asiaticum, and Trachelospermum asiaticum? We'll explain how to distinguish between similar species! Is it historically true that the name originates from "Fujiwara no Teika"? What is the ecological reason why they bloom and emit a fragrance in the evening?

Trachelospermum asiaticum and Trachelospermum asiaticum are climbing plants that can be widely found in Japan, from forests to urban areas, including cultivated varieties. They can be distinguished by the hairs on the underside of their leaves and the length of their flower tubes. They have been widely known in Japan since the time of the writing of the Kojiki, and their current names are derived from "fuji" (wisteria)...

What are the differences between Bupleurum falcatum and Bupleurum chinense? We'll explain how to distinguish between similar species! Why are they used in traditional Chinese medicine? Why are they endangered? Do flies come to the flowers to lick the nectar?

Bupleurum falcatum and Bupleurum chinense are both yellow-flowered plants belonging to the Apiaceae family that grow in sunny grasslands, so it can be difficult to distinguish between them. The difference lies in whether the base of the stem leaves clasps the stem or not. While it may not be possible to distinguish them by the shape of the flowers, there are differences in the shape of the involucral bracts...

What are the differences between trumpet vine and American trumpet vine? What are the differences between it and bellflower? We'll explain how to distinguish between similar species! Is it really non-toxic and actually poisonous?! Did they follow separate evolutionary paths in the Old World and the New World?!

The trumpet vine (Campsis grandiflora), American trumpet vine (Campsis radicans), and bellflower (Campsis lanceolata) are three species of climbing horticultural plants native to North America, commonly used as garden trees and for landscaping. Distinguishing between them is easy if they are flowering; if that's not possible, you'll need to examine the underside of the leaves closely, although the differences are minimal...

What are the differences between Salvia japonica, Salvia japonica, Salvia japonica, and Salvia japonica var. alpina? We'll explain how to distinguish between similar species! Did the flowers fit snugly onto the bees, leading to successful pollination?

Salvia japonica, Salvia japonica, Salvia japonica in autumn, and Salvia japonica in mountain are all members of the Salvia genus, known as wildflowers of Japan, but their similar names can sometimes lead to confusion. These similarly named Salvia species can be distinguished by carefully observing the structure of their corollas, stamens, and leaves...
