Care
Light
Set your auricula in a sunny to partially shaded spot, especially in warm regions where it appreciates protection from the hot afternoon sun. Good light encourages generous flowering and compact foliage. Avoid overly shaded areas that slow down blooming.
Soil and planting
This alpine prefers well-drained soil enriched with compost or leaf mould, with a slight alkaline tendency. In pots, use a draining mixture (ericaceous soil, coarse sand, potting compost). Make sure water never pools at the collar to prevent rot.
Watering
Water regularly but without excess, especially during growth and flowering periods. The soil should stay moist but not waterlogged. In winter, reduce watering. Prefer watering at the base to avoid wetting the foliage and prevent fungal issues.
Fertilizing
A moderate application of balanced fertilizer in spring is enough. If growing in a pot, a diluted light fertilizer every 15 days during flowering can support flower production. Avoid excess nitrogen which would promote foliage at the expense of blooms.
Deadheading and division
Regularly remove spent flowers to encourage new blooms. Remove dead or damaged foliage. Every 3-4 years, divide clumps after flowering to rejuvenate the plants and ensure their vitality.
Diseases and pests
Auricula mainly fears collar rot if there's standing moisture. Ensure good air circulation around the plant and impeccable drainage. It can be sensitive to red spider mites in dry conditions; mist occasionally during warm periods.
Did you know?
The auricula is one of the oldest collector flowers in Europe: in the 17th century, English and Flemish horticulturists were passionate about its varieties with golden, purple, and marbled colours, organizing competitions and exchanges among collectors. This little alpine mountain flower became a true star of classical gardening, embodying botanical delicacy and mystery.
Where to buy it
Plant in spring or early autumn, avoiding spells of intense heat. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September.
