Tiarella Varieties
Tiarella cordifolia
Tiarella cordifolia is a straight species plant native to the woodlands of North America. This beautiful perennial features heart-shaped leaves with intricate veining that creates a rich green carpet in shaded areas.
In spring, this unique shade perennial explodes with delicate spikes of starry white or pale pink flowers, giving it the common name "Foamflower" due to its frothy appearance. Tiarella cordifolia is a reliable and low-maintenance groundcover that attracts pollinators while resisting deer browsing—perfect for naturalizing areas of the garden.
Tiarella 'Oakleaf'
Tiarella 'Oakleaf' is a popular cultivar known for its striking, oak-like foliage that features deep green leaves with prominent burgundy veining. The veining intensifies during cooler months, adding a touch of drama to your shade garden.
This variety of Tiarella produces elegant white flower spikes in spring, attracting bees and butterflies to your garden. Its deer-resistant nature, combined with its beautiful foliage, makes Tiarella 'Oakleaf' a versatile choice for shaded borders, underplanting trees, or mixed containers.
Tiarella 'Timbuktu'
Tiarella 'Timbuktu' boasts deeply lobed, almost maple-like leaves that add a unique texture to shaded spaces. The foliage has dramatic burgundy veining that creates visual interest throughout the year, and in spring, it produces airy white to pale pink flowers.
This clumping perennial's compact size makes it an excellent choice for smaller gardens, mixed containers, or accent plantings. The deer resistance of Tiarella 'Timbuktu' ensures that its beauty remains unspoiled even in gardens where deer are frequently seen.
Tiarella 'Running Tapestry'
Tiarella 'Running Tapestry' is a vigorous, spreading variety perfect for creating lush ground cover in shaded areas. Its deeply lobed foliage is adorned with striking burgundy veining, which forms a tapestry-like effect across the ground.
'Running Tapestry' produces charming spikes of delicate white or pink flowers in spring. This deer-resistant perennial spreads quickly to create dense coverage, making it ideal for stabilizing slopes, filling in under trees, or covering large, shaded areas where weeds are a concern.
Growing Conditions for Tiarella Plants
Tiarella plants thrive in shaded to partially shaded areas, making them ideal for woodland gardens, under trees, or any spot that receives dappled sunlight. They prefer well-drained, humus-rich soil that retains moisture but does not become waterlogged. Consistent moisture is key to their success, especially during the establishment period. Adding a layer of organic mulch around the base of Tiarella helps keep the soil cool, retain moisture, and reduce weed growth.
The ideal pH for Tiarella is slightly acidic to neutral, similar to the natural soil conditions found in woodlands. They benefit from a moderate application of slow-release fertilizer in early spring to support lush foliage and abundant flower production. Tiarella plants are hardy and can withstand winter conditions in USDA zones 4-9, with their semi-evergreen foliage adding interest in milder climates even during the colder months.
Using Tiarella in the Landscape
Tiarella plants have numerous landscape uses, especially for creating interest in shaded areas. Their unique foliage and delicate flowers make them a wonderful choice for naturalizing under trees, filling in shaded garden beds, or creating a charming woodland garden.
Due to their ability to spread, both Tiarella cordifolia and 'Running Tapestry' make ideal groundcovers, providing a dense, weed-suppressing carpet in low-light areas. Planting Tiarella along shaded pathways or as a border plant can add softness and visual appeal, drawing attention to areas of the garden that might otherwise be overlooked.
Tiarella 'Oakleaf' and 'Timbuktu' are excellent for accent plantings where their unique foliage can be appreciated up close. Use them as specimen plants in small shaded beds or incorporate them into mixed perennial borders.
Tiarella's deer-resistant qualities make it a dependable addition to gardens that face browsing challenges. By planting Tiarella alongside other deer-resistant perennials, such as ferns and Heuchera, you can create a robust, visually appealing landscape that stands up to deer pressure.
Incorporating Tiarella into Mixed Decorative Containers
Tiarella plants are perfect candidates for mixed decorative containers, especially in shaded or partially shaded outdoor areas. Their compact growth habit, combined with their unique foliage, adds texture and interest to container plantings.
Tiarella 'Timbuktu' and Tiarella 'Oakleaf,' in particular, work well in mixed containers where their vibrant leaves and delicate spring blooms can shine. Plant them with other shade-loving companions such as Heuchera (Coral Bells), Hostas, Lamium, or ferns to create a layered and visually dynamic container arrangement.
When planting Tiarella in containers, be sure to use a high-quality potting mix that retains moisture while providing good drainage. Place the container in a location with filtered or dappled sunlight, such as a covered patio or deck.
Tiarella thrives when the soil is kept consistently moist, so water regularly, especially during hot weather. The delicate flower spikes of Tiarella will add seasonal color to the container display, while the evergreen or semi-evergreen foliage continues to provide visual interest throughout the year.
Ideal Planting Companions for Tiarella
Tiarella pairs beautifully with a wide range of shade-loving plants, making it a versatile choice for a variety of garden settings. Consider planting Tiarella alongside Heuchera, which offers an incredible diversity of foliage colors that contrast beautifully with Tiarella’s green and burgundy leaves. The mix of colors and textures creates a dynamic visual effect in shaded beds or containers.
Ferns are also excellent companions for Tiarella. Their delicate, arching fronds complement the lobed leaves of Tiarella, enhancing the woodland feel. Hostas bring bold, broad foliage that contrasts well with the fine texture of Tiarella, while Astilbes add height with their feathery plumes and contribute to the layered appearance of the planting area. By combining Tiarella with these shade-tolerant plants, you can create a cohesive and varied garden that provides continuous interest throughout the growing season.
