Complete Plant Information
Overview
Tiarella ‘Pacific Crest’, commonly known as Foam flower, presents a wonderful solution for gardeners seeking texture and reliable performance in deep shade. This rhizomatous hybrid forms dense, attractive mats of foliage complemented by delicate, frothy white flower spikes in late spring. Its patterned leaves, featuring significant maroon striping along the primary veins, provide excellent visual interest even when not in bloom.
The adaptability and low maintenance requirements make Tiarella ‘Pacific Crest’ an invaluable asset for woodland settings and tricky shady borders. It thrives best when provided consistent moisture and rich, humusy soil, mirroring its native environment. Gardeners appreciate this plant for its ability to colonize areas where sun-loving plants fail, offering robust groundcover capabilities.
As a classic woodland perennial, the Foam flower offers seasonal beauty, transitioning gracefully from spring flowering to a semi-evergreen foliage mound that brightens the winter garden structure, depending on local temperature severity. Utilizing Tiarella ‘Pacific Crest’ ensures you keep a lush, controlled presence in shaded landscapes.

How to Grow
Planting Tiarella ‘Pacific Crest’ is best achieved in the spring or early fall when temperatures are moderate. Ensure the location offers protection from intense afternoon sunlight, favoring part shade to full shade conditions. This Foam flower demands humusy, organically rich, and moisture-retentive soils that drain adequately. Avoid poorly draining sites, as wet soils, especially during winter dormancy, can prove fatal to the root system.
Maintain a consistent watering schedule, as the medium water needs mean the soil should never be allowed to dry out completely. While fertilizer is not strictly necessary if the soil is rich, occasional additions of compost will help sustain the vigor of the foliage mound. No heavy feeding is required for this low-maintenance selection.
After the initial flush of white flowers fades in May, deadheading (removal of spent flower spikes) is recommended purely for aesthetic reasons to maintain a cleaner appearance of the foliage mound. In regions with severe winters, the foliage may retain less color or density, so be prepared for this variability in winter groundcover effect.
Landscape Uses
Tiarella ‘Pacific Crest’ excels as a textural groundcover, rapidly establishing a lush carpet of patterned green and maroon leaves ideal for mass planting. It shines in woodland gardens, softening the base of deciduous trees where filtered sunlight prevails throughout the growing season. Its moderate spread of 1 to 3 feet makes it perfect for filling in spaces along the front of borders that receive limited light.
Consider using this Foam flower variety in shaded rock gardens or along the edge of naturalized areas where moisture retention is generally higher, such as near streams or ponds. The height of Tiarella ‘Pacific Crest’—under half a foot—makes it an excellent choice for edging pathways or showcasing against a contrasting, taller shade perennial like Hosta or Astilbe.
Furthermore, its compact habit and trailing form lend themselves well to container arrangements intended for shaded patios or porches. In these settings, allow it to cascade over the edges alongside shade-loving annuals or ferns for a layered design effect.

Potential Problems
This plant generally experiences very few serious insect or disease issues, contributing significantly to its low-maintenance profile. Gardeners should remain vigilant, however, for signs of powdery mildew, especially if air circulation is poor in dense plantings. Additionally, slugs and root weevils may occasionally pose a threat; early detection and routine checks beneath the foliage are the best management strategies for these common garden pests.

Companion Planting
When planning a shade garden around Tiarella ‘Pacific Crest’, select companions that share similar requirements for rich, moist, well-drained soil. Hostas of various sizes provide excellent structural contrast against the finer texture of the Foam flower leaves. Brunnera macrophylla is a superb partner, offering heart-shaped, often silver-splashed foliage that complements the striping found on Tiarella ‘Pacific Crest’.
Consider incorporating shade-tolerant ferns, such as Japanese Painted Ferns (Athyrium niponicum), to enhance the woodland aesthetic established by the Foam flower. These companions will thrive in the same part shade to full shade environment, creating layered interest throughout the season.
Design Ideas for Shady Borders
Leverage the creeping, rhizomatous nature of Tiarella ‘Pacific Crest’ to effectively manage slopes or uneven terrain in the woodland garden. Its ability to form a dense ground cover means it suppresses opportunistic weeds while providing consistent seasonal color. Use it as an edging plant where the ground slopes away from a walkway, allowing the foliage to gently spill over the edge.
For high-impact display, mass plantings of Tiarella ‘Pacific Crest’ create broad swaths of textural beauty. Plant them in groups of five or more, staggered slightly wider than their mature spread of 3 feet to encourage quick coverage. This massing technique highlights the uniformity of the spring bloom display.
Conclusion
Tiarella ‘Pacific Crest’ delivers exceptional value through its durable, patterned foliage and charming white spring flowers, all wrapped up in a low-maintenance package ideal for shaded spots. Integrating this Foam flower into your landscape ensures beautiful groundcover performance. Before planting, confirm that your location falls within USDA Zones 4-9 and that you can provide the consistent moisture this perennial prefers.
