Iris 'Margin Call'
Margin Call Iris
Iris 'Margin Call' is a tall bearded iris with beautifully patterned flowers that open in midseason. Soft buttery yellow standards rise above creamy white falls framed by broad, rich purple margins that deepen toward the outer edges. Fine purple veining radiates outward from the center, while warm yellow beards show a subtle touch of lavender at their tips. The layered coloring gives each bloom an intricate, almost hand-painted appearance.

Design tip
Place 'Margin Call' where its pale centers and deep purple edges can be appreciated from nearby. A simple backdrop of green or silver foliage keeps the intricate flowers from getting lost, while touches of soft yellow elsewhere in the bed subtly connect the planting.
