Bachelor’s Buttons or Kerria japonica

This is a bush that has been on the farm since before we arrived that I hve tried to spend little time just grooming. This year, now April 4, 2024 it is in full bloom smiling with a bit of the bright yellow sunshine in the back yard.

Kerria japonica, commonly known as Japanese kerria[1] or Japanese rose,[2] is a deciduous, yellow-flowering shrub in the rose family (Rosaceae), native to China, Japan and Korea. It is the only species in the genus Kerria. In the wild, it grows in thickets on mountain slopes. Japanese kerria has been used for medicine and is also planted in gardens. A double-flowered cultivar, K. japonica ‘Pleniflora’, is commonly called bachelor’s buttons.
