The osteospurmum crescendo color "primrose" is the offering from ECKE this year. In the past the color was "yellow" - how do these colors compare? Is the primrose a very pale yellow or a medium yellow?

Crescendo Primrose is a medium yellow color with a dark blue eye. It is a lighter yellow than Crescendo Yellow. It's habit is upright to mounding with good vigor. It is a heat lover and will continue to bloom throughout the heat of the summer. Thanks for your interest!
