The flowers of this flax are nectar-rich and robust enough that native bird pollinators can perch on the flowers and sip the nectar with their tongues. But they are equally attractive to insect pollinators, especially bumblebees. Choose a variety that has reliable and numerous flowers such as ‘Green Dwarf’. While the cookianum cultivars are great for small gardens, the
Phormium tenax varieties tend to be larger and are better suited to heavy, damp soils.
