Modern lavenders are generally a waste of good garden space - stunted mounds of dull metal-grey foliage that grow quickly, flower over the top in spring and die within a few short years. If you want lavender with longevity that is beautiful in foliage as well as flower, grow species lavenders. Lavender pinnata has such delicate foliage it's hard to believe that it is so indestructible. Pinnate leaves create a soft silver ground mound of foliage from which arises long stems topped by a soft lavender inflorescence. Flowering from spring to autumn it is rare to find pinnata without a bloom. I don't bother to prune off spent flowers, lavenders are more than capable of self-grooming. A a quick shear in mid autumn is sufficient for a tidy and trim. 0.5mH x 0.5mW (foliage height).
