The small Venus' looking-glass (Triodanis biflora) is native to North America. Its naturalization in Japan was confirmed in the 1930s and the plant can now be found across the country. The small Venus' looking-glass produces purple flowers from May to July, which resemble Triodanis perfoliata very much but it's not so difficult to distinguish them. Triodanis biflora generally produces a single flower at the apex of a stem while Triodanis perfoliata usually produces multiple flowers. How their leaves attach to the stem is also different.

ヒナキキョウソウ（雛桔梗草）です。北米原産。5月から7月に紫の花を付けます。キキョウソウ（桔梗草）とよく似ていますが、ヒナキキョウソウが先端に一つしか花を付けないのに対し、キキョウソウは複数付けることが多いです。葉の付き方も違います。
