The Brodiaea is a flower grows in our yard. It is called the hana nira which means “flower-leeks” in Japanese or and Brodiaea (Ipheion uniflora) in English.
Not be confused with the Glory of the Snow, the Brodiaea has a hollow centre and no bright yellow pistils/stamens? and its petals are shorter and stiffer , the flowers are smaller and don’t hang down gracefully like a lilies. The leaf blades are also much thinner and different.
