noun
jetbead; white kerria

I planted a jetbead in the garden.
シロヤマブキは春に白い花を咲かせる。
Jetbead produces white flowers in spring.
Refers to the yellow-flowered kerria (Kerria japonica), while シロヤマブキ is a different species with white flowers.
Literally 'white mountain kerria', from 白 (しろ, white) + 山吹 (やまぶき, kerria). The name distinguishes it from the yellow-flowered 山吹.
