Switchgrass Panicum virgatum Purple Breeze = 'Joz276' (PBR)
ABOUT
Panicum virgatum Purple Breeze, commonly known as switchgrass, is a perennial grass that is noted for its striking appearance. The 'Purple Breeze' variety exhibits a blend of green and purple foliage that adds a unique color to its display. The leaves of this plant are elongated and slender, with a linear shape that tapers to a pointed tip. The switchgrass stands upright, with a strong, vertical growth habit that contributes to its architectural presence in the landscape. The stems are sturdy and can hold the foliage aloft, which generates a sense of lightness despite its robust structure. The plant's texture is fine, with the thin leaves contributing to a dense tufted look. In terms of its color palette, 'Purple Breeze' provides a dynamic visual interest. The green of the leaves is typically deep and lush, creating a vibrant background over which the purple hues assert themselves. The purple coloration can vary in intensity depending on various factors but tends to be more pronounced in the latter part of the growing season and under certain environmental conditions. As the seasons change, switchgrass can also display a range of colors that signal the shift from the active growing season to dormancy. In the fall, the foliage may transition to shades of gold or bronze, and in some conditions, reddish-pink hues might become more obvious, giving the plant an altogether different aspect. Beyond the foliage, the plant generates airy panicles of flowers that may catch the light and animate the plant with a subtle shimmer. These flower panicles typically contrast with the foliage and can add to the texture and complexity of the plant's appearance. Overall, Panicum virgatum Purple Breeze presents a combination of upright growth, fine texture, and a compelling color shift from green to purple, with seasonal variations that keep it interesting throughout the year.

- Water
Switchgrass 'Purple Breeze' prefers consistent moisture but is also drought-tolerant once established. Water young plants regularly, about once a week, providing 1-1.5 inches of water each time to encourage deep rooting. Decrease frequency as the plant matures, watering only when the top inch of soil feels dry. During prolonged dry spells, a deep watering every two to three weeks may be necessary. If rainfall is adequate, additional watering might not be required. Adjust watering frequency based on weather conditions, always aiming to avoid waterlogged soil which can harm the plant.
- Light
Switchgrass 'Purple Breeze' thrives in full sun to achieve its best growth and form. Plant it in a location where it can receive at least six hours of direct sunlight daily. While it can tolerate some light shade, too much shade can make this grass leggy and less vigorous, potentially affecting its attractive purple coloring and overall health.
- Temperature
Switchgrass 'Purple Breeze' is hardy and can withstand a range of temperatures. It grows well in areas where winter temperatures don't drop below -20°F and can survive summer highs up to 100°F or more. The ideal growing range for this grass is between 40°F and 90°F, which promotes optimal growth and flowering without causing stress to the plant.
- Pruning
Switchgrass 'Purple Breeze' should be pruned to remove old growth and encourage a tidy appearance. Cut back the plant to about 4 inches high in late winter or early spring before new growth begins. This annual pruning helps promote healthy new growth and maintains the plant's attractive shape. Pruning at this time also minimizes the chance of damaging new shoots and gives a clean start for the growing season.
- Cleaning
As needed
- Soil
Switchgrass 'Purple Breeze' prefers a soil mix that is well-draining with a good amount of organic matter. A mix of loam, compost, and coarse sand or perlite would work well to provide the necessary drainage and nutrients. The ideal pH for 'Purple Breeze' should range between 5.8 and 7.0, which is slightly acidic to neutral.
- Repotting
Switchgrass 'Purple Breeze' is a perennial grass and typically does not require frequent repotting. It is best to repot this grass only when it has outgrown its current container or when the soil has become compacted, which is typically every 2 to 3 years.
- Humidity & Misting
Switchgrass 'Purple Breeze' is adaptable to a wide range of humidity levels and does not require a specific humidity range to thrive. Average room humidity should be adequate for this plant.
- Suitable locations
Indoor
Place 'Purple Breeze' by a sunny window; water it deeply, less frequently.
Outdoor
Plant in sun, well-draining soil; water moderately.
Hardiness zone
4-9 USDA.
- Life cycle
Panicum virgatum 'Purple Breeze', commonly known as switchgrass, begins its life as a seed, which upon germinating in the spring, develops into a small seedling. It quickly establishes a strong root system and starts producing blades of grass. Throughout the growing season, the grass matures and reaches its full height, with distinctive purple inflorescences appearing by mid-summer. The plant then flowers, and following pollination, seeds are produced by late summer or early fall, which are then dispersed to give rise to new plants. As a perennial, switchgrass dies back to the ground in winter but retains its root system, which enables it to regrow in the following spring. Over several years, switchgrass will form dense clumps and may require division to maintain vigor and control its spread.
- Propogation
Propogation time
Spring to Summer
Propogation: Panicum virgatum, commonly known as switchgrass, particularly the 'Purple Breeze' cultivar, is typically propagated by division, which is a popular method for this plant. This process is ideally carried out in the spring as the plant emerges from dormancy. To propagate by division, one must carefully dig up an established clump of switchgrass and gently separate it into smaller sections, each with a part of the root system intact. These individual divisions can then be replanted at the same soil depth as the original plant, spaced about 24 to 36 inches (approximately 60 to 90 cm) apart to allow for adequate air circulation and growth space. It's crucial to water the new plants thoroughly after planting to help establish them. This method of propagation allows for the rapid expansion of the garden with new plants that will share the desirable characteristics of the 'Purple Breeze' cultivar.
