Our savanna mix provides color from April into October and attracts many kinds of wildlife. It consists nearly entirely of perennials with a few annuals or biennials that will provide some color while the perennials get established. Many of the species can grow in full sun, but they can also grow in medium shade. This mix should be sown in late fall or winter--early February at the latest. Seed sown after February may not get the cold moist treatment (stratification) that it needs in order to germinate.
