noun
purple rock cress
A flowering plant, Aubrietia deltoidea, often used as a ground cover in gardens.
庭にムラサキナズナを植えた。
I planted purple rock cress in the garden.
The name combines 紫 (murasaki, 'purple') and 薺 (nazuna, 'shepherd's purse'), referring to the flower's color and its resemblance to shepherd's purse.
