Red Stonecrop (Sedum Spurium 'Schorbuser Blut') is a very attractive border plant that does not mind the shade and can be used as ground cover under trees and shrubs forming an expansive red carpet. Its star-shaped red flowers stand out from its beautiful dark green, slightly red leaves. Flowers absolutely anywhere. Another advantage of these plants is that they suppress the growth of weeds.
Campanula portenschlagiana or ‘Dalmatian Bellflower’ is a beautiful annual or perennial plant that forms a mat of small rounded leaves. The flowers are star-shaped, blue-purple in color that blooms from spring through summer. Relatively cold hardy but requires shelter when temperature dips below much. It grows in full sun and in the part shade too, on a fairly loose, well drained and alkaline soil
