Plant of the Week
Prairie verbena is another one of our beautiful native wildflowers that you'll see along the roadsides and fields. It has beautiful light purple, round flower clusters on short stalks. Its foliage is blue-green and velvety-looking, with highly divided leaves.
It likes shallow, rocky, disturbed soils but also grows on loam and in grassy fields. It can grow great in full sun but it can also tolerate shade, though it will have fewer flowers. It spreads easily, making it a great groundcover choice or use it to fill in your rocky paths and borders.
It will do fine on natural rainfall, but will perform a little bit better if you irrigate just a bit. But don't over water it. It stays around 6 inches tall and spreads easily to 18 inches wide and much wider if given space.
This perennial is listed as hardy to -28 degrees so these would not have trouble reemerging after a cold winter.
