WaterThe Auricula Primrose should be watered regularly to keep the soil evenly moist but not soggy, approximately once every week with about 16 ounces of water. During hotter weather or if the plant is in a pot, it may require water more frequently. It's important to ensure the pot has good drainage to prevent root rot. Water directly at the base of the plant, avoiding wetting the leaves to prevent any fungal diseases. During the winter months, reduce watering to prevent over-watering as the plant goes into dormancy.
LightAuricula Primroses thrive in bright, indirect light; direct sunlight can scorch the leaves. They are best placed in a north-facing window or a spot that receives partial shade, especially in the heat of the afternoon. Providing the right amount of light can help maintain vibrant foliage and encourage blooming.
TemperatureAuricula Primrose prefers cooler temperatures and can survive minimum temperatures down to about 20°F for short periods. They perform best in a temperature range between 50°F and 75°F. Extreme heat or prolonged temperatures below freezing are detrimental to the plant’s health.
PruningPrune Auricula Primrose to remove spent flowers and encourage further blooming, typically after the flowering season in late spring or early summer. Deadheading spent blooms will also help prevent the plant from self-seeding. Pruning away any dead or damaged foliage is also necessary for plant health and aesthetics.
CleaningAs needed
SoilAuricula Primrose thrives in well-draining soil with high organic content. The ideal pH range for this plant is slightly acidic to neutral, between 6.0 and 7.0. A mix of peat, garden loam, and perlite or sand would provide the balance of drainage and fertility suited for this Primula.
RepottingAuricula Primrose should be repotted every one to two years. It's best done in the late winter or early spring before new growth begins, ensuring minimal disruption to the plant.
Humidity & MistingAuricula Primrose prefers moderate to high humidity levels, around 50-60%. These plants do well with a humid environment but must have good air circulation to prevent fungal diseases.
Suitable locationsIndoor
Place in bright, indirect light; ensure high humidity and good air circulation.

Life cycleThe Primula auricula 'Citron-ella', commonly known as auricula or bear's ear, initiates its life cycle through seed germination, typically occurring in a temperate climate with moist, well-drained soil. Following germination, the seedling stage is marked by the development of a rosette of leaves, a characteristic feature of the species. As the plant matures during its vegetative growth stage, it forms a compact, evergreen perennial clump. The auricula then enters its reproductive phase, usually in early spring, producing distinct, bright yellow flowers with a pleasant citrus fragrance. After pollination, typically by insects, the flowers will develop into seed capsules, containing numerous small seeds ready to disperse for the next generation. As a perennial, the Primula auricula 'Citron-ella' enters a period of dormancy during the colder months, only to resume growth and flowering in the following spring.
PropogationPropogation time
Spring-Early Summer
Primula auricula 'Citron-ella', commonly known as Auricula Primrose, is a herbaceous perennial that is most commonly propagated through division. The ideal time for division is in late summer to early fall, once the flowering season has ended. To propagate by division, carefully lift the parent plant from the ground and gently separate the clumps of crowns by either teasing them apart with your fingers or using a sharp, sterilized knife. Each division should have at least one shoot and a portion of the root system attached. Replant the divisions at the same depth they were growing at previously, spacing them about 6 to 8 inches (15 to 20 centimeters) apart to allow for adequate growth. Water the new divisions well to help establish them. This method encourages a quick return to flowering and is also an effective way to rejuvenate older plants that might have become too crowded.
