Other common names: Wild iris, Blue iris
Aristea is a perennial with stiff, upright, iris-like leaves that grow in clumps up to 70 cm tall. In spring, dozens of small blue flowers are produced, which then turn into seed capsules 2cm long containing flat dark brown seeds.
Aristea tolerates a wide variety of conditions. It spreads by seeds and also by division of the rooted clumps. It can form dense stands, displacing other species and opening canopy to invasion from other weeds.
