WaterAuriculas, commonly known as Bear's Ear, have specific watering needs that prevent both under- and over-watering. They prefer consistent moisture, so it's best to water them once a week with about 1 gallon of water per plant, ensuring the soil is moist but not soggy. During hot, dry periods, you may need to increase watering frequency. Always check the top inch of the soil for dryness before watering again. It is important to avoid getting water on the leaves as this can lead to disease; instead, water at the base of the plant.
LightBear's Ear thrives in bright, indirect light with protection from the hot midday sun. The ideal spot for these plants is in dappled shade, such as under a tree or on a north-facing windowsill where they can receive plenty of light without being subjected to harsh direct sunlight. Ensure to rotate your plant periodically to encourage even growth.
TemperatureBear's Ear prefers cooler temperatures, thriving in a range between 50°F and 75°F. They can survive temperatures as low as 20°F but it's not ideal for extended periods. Protect the plant from extreme heat and freezing conditions to prevent stress and damage.
PruningPruning Bear's Ear involves the removal of dead or faded flowers to encourage further blooming and maintain plant vigor. This should be done immediately after the flowers fade. Deadheading, the process of removing spent blooms, also helps prevent self-seeding and promotes a tidy appearance. Light pruning can be done throughout the blooming season as necessary.
CleaningAs needed
SoilThe Bear's Ear (Primula auricula) thrives in well-draining, slightly alkaline soil with a pH between 6.0 and 8.0. A mix containing one-part loam, one-part leaf mold or peat, and one-part perlite or grit works well. Fertilize lightly as they prefer low-nutrient conditions.
RepottingBear's Ear (Primula auricula) should be repotted annually, best done in late summer after flowering. Use fresh soil mix to avoid nutrient depletion and to prevent the build-up of harmful pathogens.
Humidity & MistingBear's Ear (Primula auricula) prefers moderate humidity levels. A range of 50-60% is ideal, but they can tolerate slightly lower levels without much harm.
Suitable locationsIndoor
Place Bear's Ear in bright, indirect light; keep soil moist.

Life cycleThe Bear's Ear (Primula auricula), begins its life cycle when the seeds germinate in moist, well-drained soil, typically emerging in spring. As seedlings develop, they form a rosette of leaves and establish a root system. In the second year or in some cases the first, the plant produces flowering stalks with clusters of umbrella-like flowers, which can range in color from yellow to red or purple depending on the variety, usually blooming in late spring to early summer. After pollination, typically by insects, the flowers will develop into capsules containing numerous tiny seeds. As the capsules dry, they split open to release their seeds, completing the reproductive cycle. The plant often enters a period of dormancy after flowering, with the foliage dying back and the plant surviving off stored energy in its root system until the next growing season begins.
PropogationPropogation time
Spring-Early Summer
Propogation: The most popular method of propagating the Primula auricula, commonly known as Auricula Primrose, is by division, which is ideally done after the plant has finished flowering in late spring or early summer. To propagate by division, one should carefully lift the plant from the soil and gently separate the clumps into smaller pieces, each with a portion of root and a few leaves. These divisions should then be replanted at the same soil depth they were growing at originally, spaced approximately 6 to 12 inches (15 to 30 centimeters) apart to ensure adequate room for growth. The soil should be well-draining and the divisions should be kept moist until they are established. Propagating Auricula Primrose in this way helps to revitalize older plants that may be centering or declining in vigor, while also increasing the number of plants in a garden.
