Add splashes of color to your hedges to make them eye-catching. Here, we can't help but admire Catmint 'Walker's Low' (Nepeta racemosa) planted in mass, whose spikes of lavender blue flowers are absolutely outstanding. Depending upon your climate, flowering begins in mid spring and often continues through early fall. Aside from its good looks, this perennial offers many qualities: it is fragrant, dear repellent and drought resistant. Its noteworthy qualities have earned it many awards including the Award of Garden Merit of the Royal Horticultural Society (2012) and Perennial Plant of the Year (2007).
