Nemesia

Nemesia is a diverse genus of southern African flowering plants that includes annuals, perennials and subshrubs. Species and garden selections vary in habit, hardiness, flower color and season, so this genus-level record keeps those traits broad. The [RHS growing guide](https://www.rhs.org.uk/plants/nemesia/how-to-grow-nemesia) describes the genus and its garden use. ## Garden Character Most cultivated nemesias have branching growth and small, two-lipped flowers, sometimes fragrant. Depending on the species or cultivar, they suit bedding, borders, hanging baskets and containers. The genus is often used for cool-season color, but no single size, color or flowering period applies across all members. ## Siting and Growing Many garden forms prefer a sunny position with fertile soil that holds moisture while draining freely. Some species are tender annuals in colder regions, while others are perennial or shrubby in mild climates. Choose care and placement for the identified species or named selection rather than assuming all nemesias share the same hardiness or water needs. ## Maintenance Protect tender selections from frost and keep containers evenly moist without leaving the compost soggy. Remove spent growth when needed; pruning and overwintering practices depend on the particular species or cultivar.
