Answer: Annuals for mostly shady conditions include the following:
Spring blooming annuals; dianthus, lobelia, candytuft, forget-me-not, primrose and pansy. Summer blooming annuals; impatiens, Thunbergia alata (black-eyed susan vine), cockscomb, and caladium.
If you amend the soil with organic matter (aged-compost, aged-manure, etc.), your plants will appreciate the effort. Sandy soil drains fast, but doesn't hold moisture and nutrients the way good sandy loam will.
