Appreciation: Flowers Beside Greenway

These colorful plants that were sown by seed by the city earlier this year along the Arbutus greenway has begun to bloom. They appear to be quite hardy as it has been relatively dry since that time. What are they, some type of wildflower?

 

The red, white, pink are poppies and the yellow are Eschscholzia, California poppies. They are both rather drought tolerant. The Flanders poppies in my traffic circle are all rather dried up now though. I planted them last fall and they came through the winter and bloomed beautifully for months.

 

I think they're quite attractive and the bees seem to like them. Much more interesting than the typical lawn.
