In the Metchosin Bioblitz I came across a plant which I had not seen before called American Brooklime, Veronica beccabunga.
This plant grows as an edible herbaceous perennial in a 1 Meter square patch in amongst the grasses in the estuary lagoon . The area is only flooded with sea water in the winter at an extreme high tide with a strong east wind blowing. Close up, it has very striking flowers. The plant was in bloom on May 24, 2014.
