Technically known as a plicata, the falls of the white flowers are heavily banded with purple, the purple speckles further into the petals. The falls are almost entirely blackish purple. These have a spicy fragrance.
Bearded irises need to be planted with the rhizome, or root, just above the soil. This is because the rhizome needs to be baked by the sun in order to form flowers. Make sure that there is not too much competition from surrounding plants and remove any weeds.
