Getting To Know Tiarella - Spring Blooms Made For The Shade!

Nature Hills Nursery | February 14, 2026

Tiarella cordifolia, more commonly known as Foamflower, Foam Flower, or sometimes called False Miterwort, is an herbaceous perennial from the family Saxifragaceae. The same family as Coral Bells (Heuchera), which these unique Perennials resemble.

Derived from the Latin word "tiara", which refers to the small turban-shaped fruit that can form, you will come to love and appreciate Tiarella for its ability to thrive in the shade! Foam Flowers are also among the rare Perennials that exhibit semi-to-fully evergreen tendencies in warmer, more frost-free climates!

Getting To Know Tiarella

Native to the moist forests and woodlands of the Eastern US, Canada, and eastern Asia!

This clump-forming perennial spreads slowly by stolon's like Strawberries do, forming dense, wide-spreading, low-growing mounds of ornamental foliage over time. Great at blocking weeds and covering the ground like “living mulch”, Foam Flowers happily ramble along and multiply without getting into any trouble.

Native Foamflower has delicate green foliage and foamy spires of white blossoms. But the many cultivars available on the market start with similar lush green tones that can later develop purple to burgundy centers!

The foliage turns a lovely reddish bronze in autumn and winter once frost has touched it! But in warm climates and mild winters, the foliage can remain semi-evergreen or fully evergreen

The charming flowers of Tiarella appear in wispy plumes from early spring until early summer. They are simply enchanting!

Their namesake blossoms come in an array of foamy bottlebrushes, spark-like clusters, and starry wands that are lightly fragrant and very long-lasting! The tiny, white flowers on very long stamens draw in the pollinators and bees!

The erect, wiry, flower stems rise well above the foliage clumps and shine in the shade, but also in your cut flower bouquets indoors for a burst of unique texture and lively color.

From the scalloped leaves of the Running Tapestry Foam Flower, to the pointed-lobed, lustrous leafy mounds and pinkish blooms of the Sugar and Spice. You’ll love the dramatic flowering shoots and two-toned leaves of Pink Skyrocket, and the Cutting Edge Foamflower varieties!

Using Foam Flower In The Landscape

This lush carpet of ornamental foliage is why Foam Flowers make the front edges of any border a stunning focal point!

Spreading throughout the shade or dappled shade garden as living mulch or as a flowering groundcover, Tiarella won’t outgrow their garden beds or interfere with larger shrubs or perennials, Cottage gardens, mingling politely among them beautifully!

The perfect mass planting for shaded slopes, throughout the understory, or for naturalizing in those out-of-the-way areas without the worry that Deer and rabbits leave them alone!! Unless desperate, these beasties leave Foam Flower alone, but the beneficial insects will adore your drifts of blossoms!

Snip a few stems for bouquets and May Day nosegays!

Their smaller, space-saving size means Foam Flowers work in a wide variety of garden situations and can be enjoyed no matter how much room you have to grow them!

Keep them as delicious eye candy, "Fillers" and "Spillers" in container plantings on shaded porches and covered patios for easy potted décor!

Try mixing and matching Foam Flower with their Foamy Bells (Heucherella) and Coral Bells (Heuchera) cousins! Foamy Bells are actually a hybrid plant that originated from a cross between the two Heuchera and Tiarella North American plant species! You can also let them mingle among Bleeding Hearts, spring-flowering ephemerals, Ferns, and Astilbe for a lacy shade garden presentation!

Growing Foam Flower Perennials

This woodland perennial is easy to grow! Tiarella will tolerate light sun with afternoon shade in cold winter climates, but does best in full shade in warmer growing zones. Cold-hardy and adaptable throughout USDA hardiness zones 4 and up, Tiarella foliage color may be less vivid when they are grown in deep shade, and they will have fewer blooms.

These plants are healthier and more colorful when grown in a cool, moist area with acidic soil. Top-dress with compost and/or arborist mulch to maintain moisture levels and keep the roots cool and protected.

However, this Perennial cannot tolerate drought, and does not tolerate wet soil in the winter. Container-planted Foam Flowers will need winter protection.

Prune back the mounds in very early spring to clean away any old foliage for the new spring season, and divide the clumps every 3-5 years. Otherwise, Foam Flowers are easy-going shade garden gems that are so very underutilized in the landscapes of today!

Frequently Asked Questions

How does tiarella spread, and will it take over my garden?

Tiarella spreads slowly via stolons, similar to strawberries, forming dense low-growing mounds that gradually expand over time without becoming invasive. Unlike aggressive groundcovers, Foamflower is well-behaved and stays manageable, making it ideal for filling in shady spots as a weed-suppressing living mulch. To keep clumps tidy and contained, simply divide them every few years in spring or fall and replant the divisions to fill new areas of your shade garden.

Is tiarella a perennial that comes back every year?

Yes, tiarella is a true herbaceous perennial that reliably returns each year. In warmer, frost-free climates it can behave as a semi-evergreen to fully evergreen plant, while in colder regions the foliage dies back but the plant re-emerges in spring. Plant it in a moist, shaded spot and it will slowly spread by stolons to form dense, weed-suppressing mounds that get better and fuller with each passing season.

Does foam flower come back reliably in cold climates?

Yes, Foamflower (Tiarella cordifolia) is a reliable herbaceous perennial that returns each spring in cold climates, as it is native to the moist forests of the Eastern US and Canada where winters can be harsh. The foliage dies back with frost but the plant overwinters well in the ground, sending up its charming foamy flower spires again from early spring through early summer. In warmer climates with mild winters, it can even remain semi-evergreen to fully evergreen. Plant it in a moist, shaded spot and apply a light layer of mulch over the root zone in fall to give it extra protection through the coldest months.

Are foam flowers deer resistant enough for woodland gardens?

Tiarella, or Foam Flower, is generally considered deer resistant, making it a smart choice for woodland gardens where deer pressure is a common concern. These native perennials thrive naturally in moist forest settings across the Eastern US and Canada, meaning they are well adapted to exactly the kind of environment where deer browse. For best results in a woodland garden, plant Foam Flowers in dappled to full shade with consistent moisture, and consider pairing them with other deer-resistant shade perennials like Heuchera to create a dense, low-maintenance groundcover that discourages browsing.

Can you divide and split tiarella to multiply your plants?

Yes, Tiarella can be divided to multiply your plants, and division is best done in early spring just as new growth emerges or in early fall when temperatures cool. Because Foamflower spreads naturally by stolons, much like strawberries, the plant forms distinct clumps that separate easily with a sharp spade or garden fork. Dig up the parent clump, gently tease or cut apart the rooted sections, and replant divisions at the same soil depth in a shaded, consistently moist location. Water new divisions thoroughly and keep the soil evenly moist for several weeks until they establish.

Should you deadhead tiarella after it blooms?

Deadheading tiarella is not strictly necessary, but removing spent flower stems after the blooms fade in early summer helps keep the plant looking tidy and can encourage a second flush of blooms in some cultivars. Use clean garden scissors or shears to snip the wiry flower stems down to the base of the foliage mound once the blossoms have finished. Leave the ornamental foliage intact, as it provides season-long interest and will develop beautiful reddish bronze tones come fall.

How quickly does tiarella spread in shady garden areas?

Tiarella spreads at a slow to moderate pace, gradually expanding outward via stolons much like strawberry plants do, eventually forming dense, wide-spreading, low-growing mounds of foliage over several seasons. The spread is reliable but never aggressive, making it an excellent well-behaved ground cover that blocks weeds without overtaking surrounding plants. To encourage faster coverage in shady areas, plant multiple specimens 12 to 18 inches apart and keep the soil consistently moist, as Foamflower thrives in the moist, woodland conditions that mimic its native Eastern US habitat.

Can tiarella tolerate morning sun or does it need full shade?

Tiarella performs best in partial to full shade, but it can tolerate morning sun as long as it receives protection from harsh afternoon rays. Native to moist woodland environments, it thrives under the dappled light of a tree canopy or on the north or east side of a structure. Planting it where it receives direct sun only in the cooler morning hours will keep the foliage looking its best and prevent scorching, especially in warmer climates. Choose a spot with consistently moist, well-drained soil and you will be rewarded with those signature foamy blooms from early spring through early summer.

What type of soil does tiarella grow best in?

Tiarella thrives in moist, well-drained, humus-rich soil that mimics its native woodland habitat. As a plant native to the moist forests of the Eastern US, Canada, and eastern Asia, it naturally prefers soil with good organic matter content that retains moisture without becoming waterlogged. Amend your planting area with compost before planting to improve both drainage and moisture retention, and apply a layer of organic mulch around the plants to keep roots cool and consistently moist throughout the growing season.

When is the best time to plant tiarella for strong spring blooms?

Plant tiarella in early fall to allow roots to establish before winter, or in early spring once soil temperatures have warmed and frost risk has passed. Fall planting gives the plant a head start so it can channel energy into blooming come spring rather than establishing a root system. Choose a site with moist, well-draining soil in partial to full shade, and water consistently through the first growing season to set your foamflower up for its best display of spring blooms.
