I planted 20 Iris 'Harmony' in the wildflower garden. These are miniature iris with lavender uprights and bright purple falls.
I also gathered more wildflower seeds and planted them in the prairie garden.
EDIT: I went back out and planted 6 Daffodil 'Thalia' in the purple-and-white garden. They are narrow-leafed white daffodils.
EDIT: I planted 12 Puschkinia / Lebanon Squill in the purple-and-white garden. These put out clusters of star-shaped flowers in white to pale blue.
