Summer flowering from strong rhizomes

The group Iris perennials includes species such as Iris Germanica (bearded iris), Iris Siberica and Iris pseudacorus. These rhizome-forming irises offer impressive flowers in late spring and early summer, with a strong structure and long life. They are very suitable for borders, natural gardens and planting around water features. These plants combine ornamental value with ecological benefits and require little maintenance.

Perennial iris plants – structure, flowering and biodiversity

Iris as a perennial is valued for its stately form, showy flowers and versatility in garden design.

This group is ideal for landscaping, long-term planting and combination with grasses, geraniums or alliums.

Application:

  • Borders and flower boxes with height and texture
