Switchgrass Panicum virgatum 'Heiliger Hain'
ABOUT
Panicum virgatum 'Heiliger Hain', commonly known as switchgrass, is a perennial grass known for its upright, clump-forming growth habit. The leaves of this variety possess a bluish-green hue during the growing season and tend to turn a striking gold or orange in the fall, providing year-round visual interest. The overall form is characterized by its dense, feathery texture, which comes from the small flowers that develop in panicles (loose branching clusters) and can add a soft, airy quality to the plant. As the season progresses, these flower panicles may transform into a light, tan color that persists into winter, offering an aesthetic appeal even in dormancy. The foliage and stems, which maintain an attractive appearance throughout the growing season, can become an appealing beige in the colder months. The plant's ability to maintain structure and interest throughout different seasons makes it a desirable choice for landscapes that seek year-round ornamental value.

WaterFor the Switchgrass 'Heiliger Hain', it requires consistent moisture, especially during its establishment period in the first growing season. After establishment, it is more drought-tolerant and should be watered deeply but infrequently, allowing the soil to dry out slightly between waterings. The ideal approach is to provide about 1 inch of water weekly, which translates to about 0.6 gallons per square foot per week. During particularly hot or dry periods, you may need to water twice a week to maintain soil moisture, but avoid overwatering as well-saturated soil can lead to root rot. In winter, reduce watering significantly, only providing water if there are extended periods of dryness.
LightSwitchgrass 'Heiliger Hain' thrives best in full sun conditions, which means at least 6 hours of direct sunlight daily. It can tolerate partial shade, but for optimal growth and form, a location with full sun exposure is ideal. Avoid deeply shaded areas as this can lead to poor growth and a less robust plant.
TemperatureSwitchgrass 'Heiliger Hain' is fairly adaptable to temperature, typically tolerating a range from about -20 to 90 degrees Fahrenheit. However, for ideal growing conditions, maintaining a temperature range between 70 and 85 degrees Fahrenheit is preferred. It's a hardy plant that can survive winter freezes and in summer, it can withstand high temperatures without faltering.
PruningPruning the Switchgrass 'Heiliger Hain' involves cutting back the dead foliage in late winter or early spring before new growth begins. This helps maintain a tidy appearance and encourages healthy, vigorous growth. It is recommended to prune annually during this time frame. Pruning also allows for better airflow which can reduce the risk of fungal diseases.
CleaningAs needed
SoilSwitchgrass 'Heiliger Hain' thrives in a well-draining soil mix with a pH range of 5.0 to 7.0. A blend of loamy soil, coarse sand, and peat or compost is ideal to support its growth.
RepottingSwitchgrass 'Heiliger Hain' is a perennial grass that typically does not require frequent repotting. It is best to repot or divide the grass every 3-4 years to rejuvenate its growth and manage its size.

Life cyclePanicum virgatum 'Heiliger Hain', commonly known as switchgrass, begins its life cycle as a seed that germinates in spring when soil temperatures get warm enough. After germination, the seedling emerges and starts to develop a complex root system while growing its first shoots above ground. Over the growing season, the switchgrass enters a vigorous growth phase, forming tall, sturdy stems and narrow, lance-shaped leaves, and it thrives in full sun and well-drained soil. By mid-summer to late summer, the plant produces feathery, open-pollinated flower panicles that are wind-pollinated. Following pollination, seeds are produced that mature by autumn and are dispersed by wind or wildlife, allowing for the natural propagation of the species. In winter, the above-ground growth of switchgrass dies back, but the plant's robust rhizomes help it to survive the cold and regenerate the following spring.
PropogationPropogation time
Spring to Summer
Propogation: Panicum virgatum 'Heiliger Hain', more commonly known as 'Holy Grove' switchgrass, is typically propagated through seed or by division. The most popular method is by division, which is best done in the spring. Divide the clumps into sections ensuring that each section has a healthy portion of roots and shoots. These sections should then be replanted immediately at the same soil depth they were previously growing. Water the newly planted divisions well to encourage root establishment. This process not only propagates the plant but also rejuvenates older clumps that may have become woody and less vigorous.
