Perovskia 'Blue Spire', 15L Interior Books bell-shaped flowers flushed with purplePerovskia 'Blue Spire' is a useful perennial for late summer colour. Its tiny, violet blue, tubular flowers appear on silver grey spikes from August, forming a haze above deeply divided leaves that smell of both sage and lavender (and attract pollinating insects). This large specimen offers instant impact, and needs a position in full, unshaded sun to perform at its best.
