Seed source sites of Protea repens used in the common garden at Kirstenbosch, South Africa, and their respective annual rainfall and temperature patterns from 30-year climate averages. For each of the 19 sites, the mean monthly rainfall and temperature are plotted on a consistent scale, following the inset for the common garden (vertical height of shaded grey blocks is 30–55 mm rainfall or 8–14 °C). The two ‘Selection in the wild’ sites were used for detailed study of traits, ecophysiology and fecundity. For Kleinmond, seed collection and ecophysiology were from the same local population, but for De Hoop the two sites were 13 km apart.
