Seasonal blue is named after weather, which is the most honest thing a color can be named after. The alpine aster has been at altitude long enough to understand that the weather has opinions and the weather wins. It is blue when it wants to be and working something out the rest of the time. The Seasonal Blue Alpine Aster is a ceramic wall flower, 3.5 inches across, one screw, no water. Seasonal blue is not a compromise. It is a very mature understanding of the situation, and the aster arrived at it without being asked.
