Moon carrot is an interesting flowering plant. Since it is a biennial, the first growing season it grows only a small mound of finely cut, blue leaves. The second growing season, it produces umbels of white flowers across the whole plant, giving it an unusual appearance.
Moon carrot is an interesting-looking plant and generates much curiosity at the Xeriscape Demonstration Garden. It is well adapted to Colorado Springs climate. It generates a lot of seedlings which must be thinned aggressively.
Because it dies after it flowering during its second growing season, plant it in places where you don't need a permanent plant.
Plants die after flowering and should be removed in the fall. This plant spreads by seed prolifically, so remove unwanted seedlings while they are still small.
