It's been warm recently, and finally cold winter seems to have gone. Then turions of Utricularia japonica in my cultivation have started floating and forming small leaves. Hopefully spring will be coming very soon.
They are originated from Niigata prefecture Japan as my friend living there sent them to me exactly a year ago. I could keep the plant growing with no trouble last year and hopefully this year too.
These photos below are U. japonica in a growing term last year. It is said this bladderworts is a natural hybrid between U. australis and U. macrorhiza. The appearance doesn't so much differ from U. australis but the shape of the turion is round while the one of U. australis is elliptical. So they can be distinguished only in winter in my cultivation.
These are the turions of U. australis native to Shiga prefecture Japan. They look like almonds.
