Umbrella plant (Darmera peltata)
Darmera peltata, the Umbrella Plant, is a striking herbaceous perennial known for its large, peltate leaves and early spring pink-white blooms.
Complete Plant Information
Overview
Darmera peltata, often recognized by its common name, the Umbrella plant, is a substantial, spreading perennial native to the damp woodlands of Northwestern California and Southwestern Oregon. Its most captivating feature is the large, rounded, medium green leaves, up to 18 inches wide, which are peltate—meaning the petiole attaches near the center of the leaf plate, resembling a miniature, upward-facing umbrella poised to catch rainwater. Before these impressive leaves fully emerge, the Umbrella plant displays cheerful clusters of small, pink to white flowers atop stout stems in early spring. This robust Darmera peltata brings architectural interest and reliable ground coverage to consistently moist shaded environments.
This thick-rhizomed perennial offers low maintenance once established, provided its essential moisture needs are met throughout the season. Because it thrives in stream banks and moist woodland understories, gardeners must successfully replicate these conditions for optimum performance. While it is valued for its bold texture, gardeners should note that the large foliage of the Umbrella plant is prone to scorching if the required wet soil conditions are allowed to dry out, especially in warmer climates.
The visual impact of the Darmera peltata, transitioning from early floral display to dense, uniform foliage, makes it an excellent specimen for creating structure in large-scale shade gardens. Its rhizomes also provide functional stability along water features, making it a versatile choice for specialized landscape applications where moisture is abundant.

How to Grow
Planting should occur when soil is workable, favoring areas that receive consistent moisture year-round. The Darmera peltata fundamentally requires average, medium to wet soils; poor drainage or extended dryness is detrimental. While it prefers the dappled light of part shade to full shade, the Umbrella plant can tolerate full sun only if the soil remains consistently moist, bordering on wet. Avoid planting in settings prone to drought, as leaf scorch is a direct result of inadequate water.
Routine care focuses entirely on moisture management. Keep the soil consistently hydrated, especially during hot summer months, which is critical for preventing foliage damage. Fertilization is rarely necessary if the soil quality is decent, as this native perennial is self-sufficient in its preferred habitat. No routine deadheading or shaping is required; allow the foliage mound to develop naturally after flowering concludes.
For cool summer climates, Darmera peltata is exceptionally reliable. Gardeners in regions with hot and humid summers—the deep South, for instance—will find this plant struggles significantly and should seek alternatives or provide intensive cooling measures. In late winter or very early spring, trim away any dead or damaged foliage before new growth emerges, although the plant is largely self-cleaning.
Landscape Uses
The large scale and dense habit of the Umbrella plant make it ideal for substantial landscape roles rather than small borders. It excels as an anchor plant in Rain Gardens due to its high water tolerance and ability to handle saturated conditions. Furthermore, this substantial plant is extremely effective planted along the margins of streams, ponds, or bog gardens where its rhizomes help naturally stabilize moist banks against erosion.
When designing shaded areas, combine the bold texture of Darmera peltata with finer-leafed companions that share similar moisture needs, such as ferns or large Hostas. It performs wonderfully in moist woodland garden settings where it can mimic its native habitat between larger trees. Because it spreads via rhizomes, ensure it has ample room—3 to 5 feet of spread—to develop its impressive colony structure without encroaching on manicured pathways.

Noteworthy Characteristics
Darmera peltata, commonly called umbrella plant, is thick-rhizomed perennial which typically grows 3-5’ tall and is native to mountain stream banks and woodlands from southwestern Oregon to northern California. Features small pink to white flowers (to 1/2”) in terminal, rounded clusters (corymbs) which appear atop thick hairy stems in early spring before the foliage. Large, rounded, medium green, toothed and lobed leaves (to 18” across) emerge after bloom to form a foliage mound which remains attractive throughout the growing season as long as consistent moisture is supplied. Leaves are peltate (as the species name suggests)… Meaning that each leaf arises from the rhizome on a long petiole which attaches to the center of the leaf, thus creating a large leaf cup. Upward facing leaves typically collect and hold small pools of rain water.

- Erosion
- Wet Soil
Potential Problems
The primary challenge when cultivating the Umbrella plant is maintaining consistent soil moisture. Leaf scorch is a common visual sign that the soil has dried out beyond the plant’s tolerance, leading to browning and wilting of the large leaves. Ensure deep, regular watering, especially during dry spells or heat waves.
Fortunately, Darmera peltata generally suffers from no serious insect or widespread disease problems when grown outside of its optimal environment. By providing the cool, moist, shady conditions it evolved in, cultural stress is minimized, thereby reducing susceptibility to any secondary pest issues.
Frequently Asked Questions
What hardiness zones is Umbrella plant suitable for?
Darmera peltata is suitable for USDA Zones 5 through 7, requiring protection if planted in areas colder than Zone 5.
How large does Darmera peltata grow?
The Umbrella plant typically matures to a height between 3 and 5 feet tall, with a spread ranging from 3 to 5 feet wide.
What sun exposure does Umbrella plant need?
This species prefers part shade to full shade. It can tolerate more sun only if the soil moisture level is kept consistently medium to wet.
When does Darmera peltata bloom?
The Umbrella plant blooms in April, producing clusters of small pink to white flowers before the main foliage fully develops.
Conclusion
The Darmera peltata offers gardeners a robust, architectural element perfect for transforming difficult wet, shady corners of the landscape. Its unique peltate leaves and minimal maintenance requirements make the Umbrella plant a standout choice for moisture-rich naturalistic designs. Before planting, confirm that your site falls within USDA Zones 5-7 and can absolutely guarantee consistent soil wetness for this magnificent perennial.
Companion Planting
Given the high moisture demands and shady preference of Darmera peltata, companion plants should ideally share similar cultural needs. Consider pairing the Umbrella plant with moisture-loving ferns, such as Large-leaved Japanese Iris (Iris ensata), or moisture-tolerant astilbes for complementary flower textures throughout the season. These companions thrive in the damp edge conditions that the Darmera peltata prefers.
For areas near water margins where rhizomes are needed for stabilization, Water Forget-Me-Nots (Myosotis scorpioides) or various sedges (Carex species) offer excellent textural contrast while benefiting from the saturated soil environment required by the Umbrella plant. Always position plants so that the large leaves of the Darmera peltata do not completely smother smaller companions seeking light.
Design Ideas for Shade Gardens
The bold scale of the Umbrella plant shines when used as a background structural element in a woodland garden composition. Plant it behind shorter groundcovers to allow its large leaves to create an impressive backdrop, especially where the terrain slopes toward a pond or stream. Its uniform height (3–5 ft) allows for sweeping drifts that provide excellent visual mass.
Utilize the peltate leaves to their fullest potential by planting near subtle uplighting in the evening; the way the broad leaves catch and reflect light, sometimes holding small pools of mist or dew, creates a magical effect reminiscent of its native environment. Think of the Umbrella plant not just as a foliage plant, but as a living sculpture for deep shade areas lacking other bold forms.
