Fun Facts
- 🌱 The 'Helmond Pillar' cultivar was developed in the Netherlands and is named for the city of Helmond; it is one of the narrowest barberry cultivars available, reaching only 3-4 feet wide even at full maturity.
- 🌱 Japanese barberry has become invasive in many parts of North America, but the Helmond Pillar cultivar is sterile or nearly sterile, making it a more responsible ornamental choice that does not self-seed uncontrollably.
- 🌱 The deep red foliage of Helmond Pillar is due to anthocyanin pigments, which intensify in full sun and cool temperatures, making fall color especially striking in cooler climates.
