Blue Flowers

English Bluebell

Hyacinthoides non-scripta

HEIGHT to 50cm. Attractive hairless, bulbous perennial that grows in woodland and also on coastal cliffs. In wooded areas where the management regime suits its needs (sympathetically coppiced Hazel is ideal) it forms extensive and continuous carpets on the woodland floor. FLOWERS Bell-shaped, with 6 recurved lobes at the mouth, bluish purple (very occasionally pink or white); in 1-sided drooping-tipped spikes (Apr-June). FRUITS Capsules. LEAVES Long, 15mm wide, glossy green and all basal. STATUS Widespread throughout, and sometimes locally abundant.

Spanish Bluebell

acinthoides hispanica

HEIGHT to 40cm. Bulbous perennial that grows in woods and hedges. Similar to Bluebell but separable by studying leaf size and flower structure. FLOWERS Bell-shaped, bluish purple, the 6 lobes not recurved at the mouth; in spikes that are not 1-sided (May-June). FRUITS Capsules. LEAVES Basal, long and up to 35mm wide. STATUS Garden plant that is naturalised locally. The hybrid H. non-scripta x H. hispanica is more popular in gardens, and more widely naturalised, than Spanish Bluebell. Confusingly, plants show a spectrum of characters intermediate between the two parents.

Field Forget me Not

HEIGHT to 25cm Variable downy, branching annual. Grows in dry grassland, disturbed soil and arable land and verges. FLOWERS 5mm across, with 5 blue lobes, the corolla tube shorter than the calyx; in forked clusters (Apr–June). FRUITS Nutlets. Fruit stalks longer than calyx, which is coated in spreading, hooked hairs. LEAVES Oblong, the basal ones forming a rosette. STATUS Widespread and common, except in the north.

Slender Speedwell

Veronica filiformis

PROSTRATE Mat-forming, downy perennial with creeping stems. Grows in short grassland, sometimes on lawns. FLOWERS 8–10mm across, the corolla 4-lobed and bluish with a white lip; on relatively long, slender stalks arising from leaf axils (Apr–July). FRUITS Seldom produced. LEAVES 5–10mm across, rounded to kidney-shaped, blunt-toothed and short-stalked. STATUS Introduced; now locally common in the south.

Sheep’s -bit

Jasione montana

HEIGHT to 30cm Attractive, spreading, downy biennial that grows in dry grassland, and on coastal cliffs, heaths and dunes, favouring acid soils and absent from calcareous locations. FLOWERS Sky-blue, in rounded heads, 20–35mm across, on slender stalks (May– Sep). Anthers not projecting (cf. Devil’s-bit Scabious). FRUITS Dry capsules. LEAVES Wavy-edged, hairy at the base, forming a rosette, but narrow on the stem. STATUS Widespread but local, and commonest in the west and near the sea.

Cornflower

Centaurea cyanus

HEIGHT to 90cm Creeping perennial with upright flowering stems that are winged below leaf stalks and swollen beneath flower heads. Grows in arable fields and on disturbed ground. FLOWERS In heads 15–30mm across, with bluish outer florets and reddish-purple inner florets (June–Aug). FRUITS Hairless. LEAVES Narrow; basal ones may be lobed. STATUS Formerly a common arable ‘weed’, before modern agricultural herbicides; now virtually extinct on farmland, seen mainly where seed is deliberately scattered.l

Common Field-Speedwell

Veronica persica

PROSTRATE Straggling, hairy, branched annual with reddish stems. Grows on bare soil, cultivated arable fields and disturbed ground. FLOWERS 6–8mm across, the corolla 4-lobed and mainly pale blue, but with white on the lower lip; solitary and on rather long, slender stalks arising from leaf axils (Jan–Dec). FRUITS Broad, flattened capsules, with keeled lobes. LEAVES Pale green, oval, toothed and in pairs. STATUS Probably not native but now widespread and common.

Germander-Speedwell

Veronica chamaedrys

HEIGHT to 20cm Delicate and attractive perennial with creeping stems that root at the nodes, and upright flowering stems that have 2 lines of hairs. Grows in grassy places, in meadows and open woodlands, and on verges. FLOWERS 10–12mm across, the corolla 4-lobed and blue with a white centre; on slender stalks in open, terminal spikes (Apr–June). FRUITS Flattened, hairy, heart-shaped capsules. LEAVES Oval, toothed, hairy, short-stalked. STATUS Widespread and common throughout.

Wild Teasel

Dipsacus fullonum

HEIGHT to 2m Biennial of damp and disturbed grassland on heavy soils. Stems are angled, with sharp prickles on the angles.

LEAVES Spine-coated, appearing as rosettes in the first year; in the second year these die back and stem leaves are opposite and joined at the base, the resulting cup collecting water. STATUS Widespread and common in the south; scarce or absent elsewhere.
