Blue Bubikopf, also known as Isotoma fluviatilis or Pratia pedunculata, is a delightful, fast-growing ground cover with small light blue flowers. Because it is easy to walk on, it is often used for planting the joints between stone slabs. The blue Bubikopf blooms from June to September, so you have beautiful garden paths all summer long. The maximum height of growth is 5-10 cm, depending on the variety. Areas with sun or partial shade are the perfect location for these plants.
