Growing Aruncus (Goatsbeard)

Latin Name Pronunciation: uh-run' kus 

Aruncus is a small genus of hardy, herbaceous perennials from damp, mountainous woodlands throughout the temperate Northern Hemisphere. They require moist, fertile soils and part shade, but tolerate deep shade and, in cooler areas, full sun if given steady moisture; they struggle with hot, humid summers. Plants mature slowly but are long-lived, unbothered by deer or rabbits, and rarely require dividing.

Light: Part to full shade. Give your Aruncus plants more shade in hotter climates. They can tolerate full sun in cool regions with sufficient moisture.

Soil: Moisture-retentive, humus-rich soil, as found in rich deciduous woodlands. Aruncus prefer slightly acidic to neutral soils. Apply an organic bark or leaf mulch that will increase tilth and fertility as it decomposes.

Watering: Moderate to high watering needs. Consistent moisture is a must, especially in hot or dry weather or when planted in a sunny location.

Fertilizing: Compost is all that is needed when soil is rich with organic matter. Decomposed leaves, as would naturally nourish these plants in their native forest habitat, are ideal. Apply a balanced, slow-release, granular fertilizer in early spring if needed.

Continuing Care: Aruncus requires very little care other than ensuring adequate moisture. Compost and mulch applied in spring and touched up before winter is beneficial. Tall, flowering stems may be removed once flowers have faded, or left to dry on the plant for textural interest. After foliage is killed by frost, plants can be cut down to the ground in fall or spring.

Pests/Diseases: Generally unbothered by pests or diseases. Ensure good air circulation to prevent powdery mildew or other fungal diseases in especially hot, humid weather.
