Coreopsis
This is a very nice Coreopsis (tickseed) growing in a container on our back patio. I like these larger-petaled Coreopsis flowers more than the fine-petaled varieties. I suppose they both have their uses but these are so much bolder and brighter. They certainly make a good show and outside the kitchen door is a nice place for a big splash of yellow. These are reliable blooms and come ahead of the sea of black-eyed Susans that fill our backyard later in the summer. For now, these are the sole source of this color in our garden (there are a few yellow irises but they are a much paler yellow).
