These low, matted plants grow with tightly packed stems and overlapping oval leaves. Their star-shaped flowers, which range from magenta to purple, grow in a cushion shape, adding an important pop of color to an otherwise monochromatic environment.
Purple saxifrage is also one of the earliest blooming plants in the tundra, flowering as early as April in the mountains and June in the Arctic. The plant is the centerpiece of the International Tundra Experiment, which researches the impacts of climate change on tundra ecosystems.
