Seedling traits of the understorey forest plant Milium effusum along a latitudinal gradient: (A–C) ex situ collected seeds from the southernmost common garden (Belgium, 50·9°N); (D–F) ex situ collected seeds from the central common garden (southern Sweden, 55·5°N); (G–I) ex situ collected seeds from the northernmost common garden (northern Sweden, 63·8°N).
