Geranium x cantabrigiense "Biokovo"

Hardy geraniums are different from what most people think of as geraniums, which are really Pelargoniums.  These flowers are completely hardy to zone 3 usually.  They vary greatly in stature and habit, many low growing and making superb ground covers.  They grow in ordinary soil in sun or part shade.   They are somewhat drought tolerant, but not very heat tolerant.  Although rated to zone 8, here in hot zone 8b, many do not survive.  This variety is supposed to be more heat tolerant than others.  I planted last fall, will see how it survives the heat of this summer.
