Salvia 'Victoria Blue' is considered the gold standard for uniform, reliable, vertical colour in a garden. It features multiple upright stems topped with dense spikes of vivid indigo-blue flowers that bloom for months.
Its botanical name, farinacea, refers to the "mealy" or flour-like dusting on the flower stems, which creates a silvery-white appearance that makes the deep blue petals appear to glow. The plant is neat, bushy, and highly heat-tolerant, making it ideal for patio pots in sunny locations.

Salvia farinacea 'Victoria Blue' is a Half-Hardy Perennial (H3). In the UK, it is typically grown as a Half-Hardy Annual because it cannot survive our cold, wet winters outdoors. It holds the prestigious RHS Award of Garden Merit (AGM) for its consistent performance.
The "Mealy" Characteristic: The stems and calyces are covered in fine, silvery hairs (the mealy coating), which provides a striking contrast to the intense indigo blooms. This unique texture also makes the flower spikes particularly resilient to wind and rain.
Pollinator Star: Officially listed as an RHS Plant for Pollinators, 'Victoria Blue' is a high-nectar variety that is particularly favoured by honeybees and butterflies. Its compact, bushy habit (45-50cm) makes it perfect for adding "the hum of summer" to pots and border edges.
Salvias are remarkably productive, but they require a warm start to ensure they flower in their first season.
How to Sow:
Sow indoors from February to April. Surface sow the seeds onto moist compost—do not cover as they require light to trigger germination. Maintain a temperature of 20-24°C; seedlings typically appear in 10-14 days.
Where to Plant:
Plant out in late May or June once all risk of frost has passed. They demand full sun and thrive in light, well-drained soil. They are highly heat-tolerant, making them one of the best choices for sunny patios and south-facing borders.
Ongoing Care:
Pinch out the growing tips when the seedlings are about 10cm tall to encourage a bushier, multi-stemmed plant. Deadhead spent flower spikes regularly to keep the blue displays coming. A high-potash liquid feed in late summer will boost a spectacular second flush of autumn blooms.

The indigo spires of 'Victoria Blue' provide a strong, cool vertical that pairs brilliantly with these favourites:
- ☁️ Cosmos 'Purity' : The Crisp Contrast. The large, airy white saucers of Cosmos Purity provide a fresh backdrop that makes the indigo-blue spires of the Salvia look even deeper and more saturated.
- 🎨 Achillea 'Cloth of Gold' : The Complementary Duo. Blue and yellow are opposite on the colour wheel, making this a high-impact combination. The flat golden plates of the Achillea provide a perfect horizontal foil to the vertical Salvia spikes.
Sow under cover in early spring for vivid blue spires from mid-summer until frost.
