Salvia viridis 'Oxford Blue' Annual Clary Sage 'Oxford Blue'
Tall, sturdy spikes topped with intense, velvety, deep indigo-purple bracts that hold their saturated colour for weeks — the longest-lasting blue in the cottage garden, and one of the most prized cut flowers any cutting patch can produce.
If 'Crown Bouquet Mixed' is the carnival, 'Oxford Blue' is the soloist. This is the single-colour selection from the Salvia viridis family, producing tall 60–75cm spikes topped exclusively with deep, almost-violet indigo bracts that look as if they have been varnished. The intensity of the colour — and the fact that it's leaf-pigment rather than petal-pigment — means 'Oxford Blue' holds its display exceptionally well through summer rain, hot sun and (eventually) the vase. A florist's favourite for any arrangement that needs proper deep blue, and one of the very best annuals for drying. Hardy annual flowering June to October. RHS Plants for Pollinators recognised.
A note on growing
Direct sow outdoors in September for the strongest, earliest-flowering plants the following year, or March to May for a summer display. Sow at 3mm depth in well-drained soil. Full sun. Germination takes 14–21 days. Like its mixed-colour relative, 'Oxford Blue' is a cool-season specialist that establishes its best root systems in cool soil. Drought-tolerant once established but dislikes waterlogged winter ground — if you have heavy clay, sow in autumn into modules and overwinter under cover. Pinch out the growing tip at 10–15cm to encourage bushier growth and more cutting stems.
Where it shines
In the cutting garden as a structural deep-blue stem — there is nothing quite as useful as a saturated indigo for making warm-toned arrangements sing. As a dried flower, the colour holds exceptionally well if dried out of direct sunlight (UV degrades green and blue dried-flower pigments). In cottage borders, plant in generous drifts where the deep colour can do its work as a backdrop to warmer tones. In wildlife gardens, the small hidden flowers are exceptionally nectar-rich and reliably attract bees through the long flowering period.
Plant alongside
For maximum cutting-garden colour drama, pair the deep indigo of 'Oxford Blue' with the sunshine gold of Coreopsis 'Early Sunrise' or the pure white lace of Ammi majus — both are classic florist combinations that exploit the strength of the blue. In cottage borders, combine with Achillea 'Pastel Mixed' and the silvery Lychnis coronaria. For dried flower harvesting, pair with Statice in matching tones.

Be a smarter gardener
Gardening organically is a more affordable and long term alternative to using chemical fertilisers. Natural Grower products eliminate waste because the nutrients are slowly released to the plants as they need them. Over the long-term you save money because your soil health naturally improves, which in turn produces healthier, stronger, disease resistant plants. Chemical products may cost less financially in the short term, but they don’t provide any long-term benefits and the damage they do to the natural eco-system in the soil is costly.
Slow release for sustained growth
Organic fertilisers are broken down slowly by organisms in the soil to produce a more measured, consistent, natural release of nutrients. This results in uniform growth with strong stems and leaves, unlike chemical fertilisers which provide a sudden boost resulting in tall lanky plants. Stronger plants are more resistant to disease, and with the presence of mycorrizhal fungi to strengthen the roots, the plants, soil and fungi all work together long-term to create the perfect natural eco-system.
Love your land
The organic matter in Natural Grower will help keep your soil or compost in optimum condition, retain moisture over the dry summer months and improve the health and structure of your soil. The presence of natural Mycorrhizal fungi in our products enhances root growth, enabling plants to extract nutrients and absorb water more efficiently from the soil or compost. By using our products you will be supporting and enhancing the natural eco-system in the soil.

Natural Grower’s chemical free fertiliser products are approved organic, biodynamic and vegan. Plant-based and free from chemicals they are safe to use around wildlife, pets and children. Eco-friendly and sustainably produced in the UK. Our packaging is made from recycled plastic where possible and is all 100% recyclable.
