Auricula

Sun

Partial shade or gentle morning sun; protect from hot afternoon sun, especially in warmer regions.

Water

Keep lightly moist during active growth, allowing excess water to drain freely. Water sparingly in winter without letting the root ball dry out completely.

Soil

Gritty, humus-containing, sharply drained soil, preferably neutral to alkaline. Avoid heavy, waterlogged ground.

Height

0.5-0.75 ft (0.15-0.23 m)

Spread

0.5-0.75 ft (0.15-0.23 m)

Flowers

Spring to early summer; fragrant yellow flowers, often with a pale, powdery centre, held in clusters above the leaves.

Foliage

Evergreen. Thick, rounded to spoon-shaped, grey-green leaves in basal rosettes, often dusted with a natural white powder.

Growth

Slow to moderate; gradually forms a clump of rosettes.

Care needed

Growth rate

Slow

• Plant with the crown at the soil surface, using a gritty mix and a container with generous drainage holes.
• Water the compost rather than the rosettes, keeping it lightly moist while new leaves and flowers develop.
• Apply a dilute balanced liquid feed occasionally during spring growth; avoid heavy feeding.
• Use a thin grit mulch around the crown instead of moisture-retentive organic mulch.
• Shelter pots from persistent winter rain while keeping them cool and well ventilated.
• Divide crowded clumps after flowering, keeping roots attached to each healthy rosette.

Pruning. Cut spent flower stems back to their base after flowering unless you want seed. Remove dead or rotting leaves carefully, but leave healthy foliage intact.

Late winter

Check drainage and remove decaying leaves; keep crowns out of standing water.

Early spring

Resume regular watering as growth starts and give a dilute balanced feed.

Spring

Watch developing flower stems for aphids and protect tender growth from slugs.

Late spring

Remove finished flower stems and divide crowded clumps after flowering.

Summer

Provide afternoon shade and keep roots cool; do not let containers bake dry.

Autumn

Move containers under an open-sided rain shelter where winters are wet, and reduce watering as growth slows.

• Plant in limestone rock gardens or crevices where small spring flowers can be seen closely.
• Grow in shallow stone troughs with saxifrages and other compact alpines for contrasting leaf textures.
• Display individual terracotta pots on a sheltered shelf near a doorway, bringing flowers and scent closer to eye level.
• Use at the front of a cool, well-drained spring border with small bulbs, away from vigorous neighbours.

Garden styles it suits: Alpine rock garden, Cottage garden, Traditional, Modern courtyard, Small-space and English country.

Plant it with: Saxifrages, Dwarf irises, Crocuses, Snowdrops and Dwarf bellflowers.

Wildlife: Flowers provide spring pollen and nectar for visiting insects. The small plants offer little cover or food for larger wildlife.

• Crown or root rot: improve drainage, keep the crown at soil level and shelter containers from prolonged winter rain; discard badly rotted plants.
• Vine weevil: larvae eat roots and cause sudden collapse; inspect container root balls and use suitable biological controls according to local instructions.
• Slugs and snails: protect young leaves and flower buds with hand-picking or locally approved slug controls.
• Aphids: check flower stems and new growth, removing colonies by hand or treating with insecticidal soap labelled for ornamental plants.

Do not eat any part. Primulas are reported as harmful to cats and dogs if eaten, usually causing digestive upset, but evidence specific to Primula auricula is limited. In people, handling may cause skin irritation or an allergic rash; wear gloves if sensitive. Reliable species-specific information for horses is lacking, so keep it out of grazing areas.

• Garden auricula (Primula × pubescens)

  These hybrids often have purple, red, pink or patterned flowers rather than the wild species' yellow flowers. Yellow-flowered hybrids can be difficult to distinguish without a reliable plant history.

• Common primrose (Primula vulgaris)

  Has thinner, wrinkled leaves and usually bears individual flowers on separate stalks, rather than a cluster on one upright stem.

• Cowslip (Primula veris)

  Has wrinkled, softly hairy leaves and nodding, bell-shaped yellow flowers, rather than auricula's fleshy leaves and flatter flower faces.

Auricula comes from the Latin for 'little ear', referring to the rounded leaves, which also explain the name bear's ear.

Propagation. Divide established clumps or detach rooted offsets after flowering. Sow fresh seed in gritty compost; germination can be slow and may benefit from a period of cold. Seed from garden hybrids will not reliably reproduce the parent.
