Anchusa Blue Angel

Anchusa capensis 'Blue Angel' Cape Forget-Me-Not 'Blue Angel'

Clouds of vivid ultramarine-blue flowers — possibly the truest, most electric blue available from any annual seed — held in airy sprays above a compact mound of bristly green foliage. This is the colour that gardeners spend years trying to find.

Real, intense blue is the rarest colour in the garden. Most "blue" flowers are really violet-blue, lavender, or purple-blue. 'Blue Angel' produces something different — a saturated, almost luminous ultramarine that genuinely stops you in your tracks. Bred from Anchusa capensis, the South African Cape Forget-Me-Not, it is a hardy annual that grows to a tidy 30–45cm with masses of forget-me-not-style flowers from June through to the first autumn frosts. Drought-tolerant once established, exceptionally bee-friendly, and one of the very best annuals for those tricky hot, dry, sunny spots where most plants struggle.

A note on growing

Sow indoors from February to April at 18–20°C, or sow direct from late April once the soil has warmed. Anchusa seeds benefit from light, so surface-sow or barely cover. Germination takes 10–14 days. Plant out after the last frost in full sun and well-drained soil — this is a plant that genuinely thrives on neglect once established. Lean, dry, free-draining ground produces stronger flowering than rich, moist soil. Deadhead regularly to extend the flowering season; without deadheading, plants tend to set seed and stop blooming after a single flush.

Where it shines

In hot, dry sunny borders where the intense blue creates pure contrast against silver-leaved companions and warm-toned neighbours. The colour is particularly powerful next to gold and yellow flowers — the complementary contrast is genuinely electric. In containers, where the compact habit suits patio pots, and as a cut flower for small posies and informal arrangements where the blue does the heavy lifting. Pollinators adore it — bees, hoverflies and butterflies all visit in numbers throughout its long season.

Plant alongside

For maximum colour drama, pair with the gold of Achillea 'Cloth of Gold' or the warm tones of Calendula. For a softer combination, plant with the white lace of Ammi majus and the soft pinks of Achillea 'Pastel Mixed'. As a cottage garden classic combination, try alongside Cornflower 'Snowman' for a cool blue-and-white scheme.
