How to Grow and Care for Bergenia Plants
No known diseases or plant problems. Remove all damaged foliage in late winter to early spring. Promptly remove spent flowering stems.
Bergenia crassifolia
Bergenia is a large, glossy evergreen, hebacious perennial native to shady north-facing rocks, stony slopes, and rock streams in the forest and alpine zones of China and Siberia. It is a low-growing plant to a foot high with leaves produced in spreading clumps of 2 to 3 feet and makes a lovely ground cover in shady areas. However, it can be slow to spread. Although it is considered drought-tolerant, the leaves will dry out if the soil is allowed to remain dry for an extended period. Considered to be evergreen in more temperate areas of the country, it will sustain winter damage in northern areas. The common name pigsqueek comes into play when rubbing a leaf between your fingers and producing a sound much like the animals’ squeal. The genus name honors Karl August von Bergen (1704-1759), a German physician and botanist and the specific epithet comes from the Latin words crassus meaning thick and folia meaning leaf in reference to the leathery leaves.
Bergenia grows best in moist organic soil, but tolerates sandy, loamy, and clay soils. It can grow in full shade or full sun and can tolerate drought. It will do best sited in a position sheltered from cold drying winds and from the early morning sun. The leaf colour is best when plants are grown in a poor soil in a sunny position. The plant typically blooms from March to May; however, when grown in the southernmost areas, it can bloom as early as December.
The roots, leaves, and stems contain tannin in different percentages. Tannin is used in the production of leather and ink and is also an ingredient of tea. The leaves of this plant are used as a tea substitute and give it the common name, Siberian Tea.

Despite the unflattering nickname pig squeak, so named for the sound its leaves make when rubbing together, perennial bergenia (Bergenia cordifolia) has long enchanted gardeners with their large glossy leaves and pert springtime flowers. Bergenia foliage is mostly evergreen in milder climates, exhibiting a rich bronze color in the fall and winter. The leaves are quite attractive in their own right, but when its April flowers emerge and are held aloft on stiff stems growing in dappled shade you’ll know you’ve selected a winner for your perennial flower border. The best time to plant and divide bergenia is in the spring. It grows to full maturity in two to five years.
Light
Bergenia plants are ideal candidates for the shade garden. They thrive in partial shade but will also tolerate heavy shade. But, of course, the more sun plants receive, the more moisture they will need.
Soil
Like many plants, bergenia grows well in rich, loamy soil and will expand to grow large clumps in that environment. However, bergenia can also tolerate clay soil, which you can enrich over time with a top dressing of compost.
Water
Bergenia likes consistent moisture. To maintain a moist root zone, spread a three-inch layer of mulch around the plants. Plants growing in deep shade can survive periods of drought better than those growing in a location that receives more sun.
Temperature and Humidity
Bergenia plants grow well in areas with hot or cool summers if they have enough shade and moisture. They also do well in humid areas. Winter damage is more extensive in colder climates.
Fertilizer
Bergenia plants are light feeders and do not need supplemental fertilizer to look their best. Growing bergenia plants in loamy soil amended with organic matter provides all the nutrients they need.
Types of Bergenia
- B. Cordifolia ‘Winter Glow’ has red stems and nodding pink flowers and grows to 12 to 16 inches tall and 18 to 24 inches wide.
- B. cordifolia ‘Bressingham White’ can light up a garden with clusters of white blooms. It grows to the nearly same size as ‘Winter Glow,’ if a little bit shorter.
- B. cordifolia ‘Angel Kiss’ is one of the shorter cultivars, at eight to ten inches tall and 10 to 12 inches wide. Its blooms are white to light pink.
- B. cordifolia ‘Ballawley’ might be the largest bergenia available, growing to 24 inches tall and 18 inches wide. It features rose-red flowers and red stems.
- B. cordifolia ‘Solar Flare’ is prized for its variegated leaves of green edged with yellow. This cultivar is mid-sized (10 to 16 inches tall and about 18 inches wide) and has magenta-purple blooms.
Bergenia vs. Leopard Plant
Except for its yellow flowers, the leopard plant (Ligularia dentata) bears a strong resemblance to bergenia plants. Both plants thrive in shade and feature similar large, rounded leaves with a glossy finish. However, to be healthy, leopard plants need more moisture and shade than bergenia plants, so if you have a place in the garden that transitions between sun and shade, place your leopard plants in the location with more shade.
Pruning
In general, bergenia plants need little in the way of pruning. You can cut back spent flower stalks to keep plants looking tidy in the summer. In areas where the foliage is marginally evergreen, trimming back tattered foliage will also increase plant tidiness.
Propagating Bergenia
Making new bergenia plants is as simple as the process of dividing them. Divide plants in the fall to prevent any disruption to the blooming cycle. Here’s how:
- Dig up the root ball, and tease apart a clump of foliage and roots with your fingers, as shown in the photo.
- Create big divisions with at least five to seven leaves to make an impact in the garden.
- Replant the divisions in a suitable location and water until moist.
How to Grow Bergenia From Seed
If you have patience and want to grow many bergenia plants for the landscape, you can start from seed. Seeds need light to germinate, so press them lightly into sterile potting soil. Keep the soil moist and warm while waiting for germination, which can take four to six weeks.
Potting and Repotting Bergenia
Bergenia makes an attractive container specimen. Combine bergenia with other pretty foliage choices, like coral bells and Japanese painted fern.
Bergenia plants will grow in any commercial potting soil in a pot with a diameter of at least 12 inches. Repot your plants in the spring after flowering, and divide as needed to keep plants from becoming overcrowded.
Overwintering
Bergenia will survive the winter in an outdoor container in USDA Hardiness Zone 7 and warmer. Dress bergenia with a layer of compost in early winter. Cover clumps of bergenia with straw or chopped leaves to protect them against freezing winter temperatures. This barrier protects the foliage and roots from the freezing and thawing cycle.
Common Pests and Plant Diseases
Like many plants that grow well in shady areas, bergenia plants can suffer from slug and snail damage to the foliage and are susceptible to black vine weevils. There are several ways to deal with these pests, including beer bait traps, cardboard traps, and diatomaceous earth.
Bergenia, while resistant to many plant diseases, can get fungal leaf spot and anthracnose, which is another type of looks similar to fungal leaf spot. If you notice any spots on the leaves of your plant, treat them as soon as you can. Remove any infected leaves on the plant and the surrounding ground, and treat with a fungicide. Proper watering techniques can help prevent these types of fungus.
Crown rot is another disease that can affect this plant, so be careful when planting or mulching, and leave the crown of the plant uncovered to avoid the problem
How to Get Bergenia to Bloom
Bergenia blooms during the months of April and May, showcasing small clusters of flowers that come in pink, white, or red. To keep these plants blooming, plant them in a partial to full shade location in moist, rich soil, which will help stimulate its growth and produce more blooms. If you cut down the spent flower stalks, a new stalk might grow and produce more flowers.
Plant bergenia, in the ground or a container, just to the top of the root ball. Space multiple plants about 12 to 18 inches apart.
Pollinators including bees, butterflies, and hummingbirds are attracted to bergenia flowers.
Other flowering plants that are good companion plants with bergenia include hardy geranium (cranesbill), lungwort, and brunnera.
