 Shade Tolerant Annuals
Annual flowers differ in their ability to withstand shade while maintaining attractive foliage and producing blossoms. Most annuals require some full sunlight during the day, but here is a list of plants, suitable for Idaho, that can withstand part or full shade and still be attractive.

(P) = Tolerates dappled or part-shade conditions.
(F) = Tolerates full shade conditions.
Key to regional adaptation notes:
N = Northern Idaho valley locations in USDA zones 5 & 6, Moscow to Sandpoint.
SE = Southeastern Idaho valley locations in USDA zones 3 & 4 from Rexburg to Pocatello. SC = South-central Idaho Magic Valley locations in USDA zones 4 & 5, Burley and Twin Falls.
SW = Southwestern Idaho Treasure Valley locations in USDA zones 5 & 6, Boise area (also Lewiston).
HA = High altitude (>5,000 ft) areas of central, southeastern Idaho and similar locations elsewhere.
