Cerinthe major Purpurascens

Cerinthe major 'Purpurascens' Honeywort / Blue Shrimp Plant

Glaucous silver-blue leaves that transform progressively into deep purple as they ascend the stem, crowned with drooping tubular bells of midnight purple-blue — Cerinthe is unlike anything else in the cottage garden, an architectural hardy annual with the sculptural quality of a succulent and the bee-magnetism of a salvia.

There is genuinely nothing else in the cottage garden quite like Cerinthe. The plant grows to 45–60cm with thick, almost-succulent stems lined with rounded blue-grey leaves that gradually become more violet-purple toward the top — an effect that makes the foliage almost as ornamental as the flowers. The flowers themselves are dramatic clusters of drooping, tubular bells in deep purple-blue, partially hidden under leaf-like bracts of the same purple-blue. Bumblebees adore Cerinthe — it's one of the most reliable bee plants you can grow from seed, and a single planting of Cerinthe in flower will hum audibly with bumblebee activity throughout summer. Hardy annual that self-seeds enthusiastically once established, often producing volunteer plants the following year. RHS Plants for Pollinators recognised. Beautiful as a cut flower for unusual, sculptural arrangements.

A note on growing

Cerinthe is genuinely easy if you respect a few quirks. The seeds are large and germinate easily — sow direct outdoors from March to May, or autumn-sow in September for stronger early-flowering plants the following year. Sow at 1cm depth and thin to 30cm spacing. Cerinthe has a long taproot and resents transplanting; direct sowing produces the strongest plants. If starting indoors, use deep biodegradable pots that can be planted out intact. Full sun, in well-drained soil — Cerinthe prefers lean ground over rich. Drought-tolerant once established. Self-seeds reliably; once you have it, you tend to keep it.

Where it shines

In cottage borders as an architectural feature plant — the unique foliage, stem structure and drooping bells provide genuine visual interest from May right through to autumn. In gravel and Mediterranean-style gardens where the drought-tolerance and sculptural form suit the dry conditions perfectly. As a cut flower for unusual, modern arrangements where the curving stems and dropping bells provide proper structural interest. In wildlife gardens, where the bumblebee value alone earns it a place. In containers, where the architectural form anchors mixed plantings.

Plant alongside

For a sophisticated colour-and-texture scheme, combine the smoky purple-blue of Cerinthe with the silvery foliage of Lychnis coronaria and the soft pinks of Achillea 'Pastel Mixed' — the colour palette is unmistakably cottage but elevated in tone. For a wildlife-magnet planting, pair with Agastache 'Liquorice Blue' and Echinops Ritro Veitch's Blue for a comprehensive bumblebee buffet. The unusual blue-purple foliage also works beautifully as a foil for the bright orange of Calendula 'Neon'.
