Among the plants along the shore of the pond, Arrowhead Sagittaria latifolia plants hold their leaves pointing skyward above the water.
This week, we noticed they are blooming with white, 3-petaled flowers held up above the leaves on strong branched stems.
Each flower is about 1" across.
This variety is specifically Broadleaved Arrowhead; also called 'Duck Potato' since it is a perennial plant that forms food-storing tubers as roots.
