Annuals and Perennials for Seaside Gardens

Many plants grow well by the sea, so it is not impossible or very difficult to have a seaside garden. When native seaside vegetation is supplemented by “exotics” (in this case non-seashore native plants), a garden will lack nothing that is needed to be delightful–and unmistakably a seaside garden.

At a distance of 500 feet or more from the shoreline, there is often little difference between a seaside garden and any other except for perhaps a more or less persistent wind from one direction. The presence of any large body of water has a stabilizing effect on temperature, tending to reduce the extremes of heat and cold.

Salt spray may be an element of the special conditions that prevail close to the oceanside, while soil that is light and sandy is characteristic unless the location is on an elevated coast which sometimes provides fairly good soil. These things can affect the choice of plant material.
