Shenandoah Switch Grass
Shenandoah Switch Grass
Shenandoah Switch Grass adds warm seasonal color to Minnetonka, Hopkins, and Bloomington landscapes — burgundy-red blade tips emerge in summer and deepen into a full red blaze by fall.
About Shenandoah Switch Grass
| Botanical Name | Panicum virgatum 'Shenandoah' |
| Mature Size | 3-4ft tall × 2-3ft wide |
| Bloom / Foliage | Airy pink-tinged plumes late summer; wine-red fall color |
| Sun Requirements | Full sun (6+ hrs) for most ornamental grasses. A few (Blue Moor Grass) tolerate light shade. |
| Water Needs | Low. Drought-tolerant once established — average MN rainfall is plenty. |
| Soil | Tolerates Minnesota clay-loam. Adapts to most well-drained soils. |
| Hardiness Zones | 3-8 (Twin Cities is zone 4b–5a). Reliable to -40°F for most native grass cultivars. |
| Deer Resistance | Rarely browsed — ornamental grasses are one of the most deer-proof plant categories |
| Foliage | Deciduous — grass blades emerge in spring, mature through summer, hold form (often with golden fall color) into winter |
| Growth Rate | Fast — reaches full size in one or two seasons |
Why You'll Love Shenandoah Switch Grass
Winter structure
Ornamental grasses hold their golden form through Minnesota's five-month winter — one of the few things that look great against snow. Pair with red-twig dogwood for maximum winter impact.
Pollinator + bird habitat
Grass seed heads feed birds through fall and winter. Native bunchgrass clumps are critical nesting habitat for ground-dwelling pollinators.
Low-water plantings
Once established, ornamental grasses thrive on natural rainfall — no supplemental watering needed. Perfect for boulevard strips, dry slopes, and parking-area plantings.
Red-tipped native-type switch grass
Red color intensifies as the season progresses. That's why Shenandoah Switch Grass has earned a spot in our Minnesota launch catalog — it's a grass we're confident will thrive in your Twin Cities landscape.
Planting Shenandoah Switch Grass in the Twin Cities
Best planting window: Spring (mid-April through early June) or early fall (late August through late September). Avoid planting during peak summer heat — Twin Cities heat waves can stress newly installed root balls.
Site selection: Full sun (6+ hrs) for most ornamental grasses. A few (Blue Moor Grass) tolerate light shade. Choose a location with the mature size of 3-4ft tall × 2-3ft wide in mind — give Shenandoah Switch Grass room to fill out without crowding fences, sidewalks, or neighboring plants.
Soil prep: Tolerates Minnesota clay-loam. Adapts to most well-drained soils. If your Twin Cities yard has heavy clay (common in Plymouth, Eden Prairie, and Wayzata), amend the planting hole with 25-30% compost to improve drainage. For sandy soils in parts of Anoka and Washington counties, mix in compost to improve water retention.
How to plant:
- Dig a hole 2× the width of the root ball and the same depth.
- Loosen the sides of the hole — slick clay walls block root expansion.
- Set Shenandoah Switch Grass so the top of the root ball is 1-2" above grade.
- Backfill with native soil mixed 25% with compost. Tamp gently.
- Water deeply (5+ gallons) immediately after planting.
- Mulch 2-3" deep, keeping mulch 2" away from the stem.
Watering & Care
First year (establishment): Water deeply 1-2× per week from April through October. Shenandoah Switch Grass needs consistent moisture to develop a strong root system for its first Minnesota winter. Check soil moisture 4-6" deep — water when the top 2-3" feels dry.
Established (year 2+): Low. Drought-tolerant once established — average MN rainfall is plenty. During typical Twin Cities summers, supplemental water during 2+ week dry spells is enough.
Winter prep: Water deeply in late October before ground freeze — this protects Shenandoah Switch Grass through dry winter winds. Apply a fresh 2-3" layer of mulch in November to insulate the root zone through deep freezes.
Pruning: Cut back to 4–6 inches in late winter or early spring before new growth emerges. Do NOT cut back in fall — the foliage provides winter interest and wildlife habitat.
Frequently Asked Questions
Is Shenandoah Switch Grass hardy in Minnesota?
Yes. Shenandoah Switch Grass is rated for zones 3-8 (Twin Cities is zone 4b–5a) — the Twin Cities metro is zone 4b–5a, well within its hardiness range. Red color intensifies as the season progresses.
How fast does Shenandoah Switch Grass grow?
Fast — reaches full size in one or two seasons. Expect mature size (3-4ft tall × 2-3ft wide) within 5-8 years depending on site conditions and care.
Will deer eat Shenandoah Switch Grass?
Rarely browsed — ornamental grasses are one of the most deer-proof plant categories. In high-deer-pressure suburbs (Wayzata, Stillwater, Hudson), supplemental fencing or repellents may help young plants establish.
Can I plant Shenandoah Switch Grass in part shade?
Full sun (6+ hrs) for most ornamental grasses. A few (Blue Moor Grass) tolerate light shade.
What size gallon should I buy?
We typically offer Shenandoah Switch Grass in #2, #5, #10, and sometimes larger gallon sizes. Smaller sizes establish faster and cost less; larger sizes give instant impact. For most Twin Cities residential landscapes, #5 or #10 gallon is the sweet spot.
Where We Deliver
Three Timbers Minnesota delivers and installs Shenandoah Switch Grass across the Twin Cities metro — Minneapolis, St. Paul, Plymouth, Maple Grove, Edina, Eden Prairie, Minnetonka, Wayzata, Bloomington, Apple Valley, Burnsville, Lakeville, Eagan, Roseville, Shoreview, Stillwater, Woodbury, Hudson, Hopkins, St. Louis Park, Chanhassen, Excelsior, Victoria, Chaska, and surrounding communities. Live Shenandoah Switch Grass grown for our climate and delivered fresh from our Waconia, MN nursery.
How Many Shenandoah Switch Grass Do I Need?
At 2–3 ft wide, space plants about 30 in apart for a screen or mass:
| Bed run | Plants needed (30 in apart) |
|---|---|
| 5 ft | 3 plants |
| 10 ft | 5 plants |
| 15 ft | 7 plants |
| 20 ft | 9 plants |
For a bold drift, plant in groups of 3 or more; a single clump also reads well as a specimen.
Shenandoah Switch Grass Season-by-Season in Minnesota
- Spring: Upright green blades emerge, often showing early red tips.
- Summer: Blade tips deepen to burgundy-red; airy pink-tinged plumes float above by late summer.
- Fall: Foliage blazes wine-red and the plumes catch low autumn light.
- Winter: Tan blades and seed heads stand through snow for structure and bird food; cut back in late winter.
At a Glance

Plant It With
- Shining Star Bluestem — a native bunchgrass with steel-blue verticals for a layered prairie look
- Prairie Dropseed — a fine-textured native grass for the front of the planting
- Magnus Coneflower — a prairie pollinator partner that pops against the blades
- Autumn Fire Sedum — a companion whose seed heads share the winter interest
Is Shenandoah Switch Grass Right for Your Yard?
It takes full sun and almost any well-drained soil, including clay, and is tough, drought-tolerant, deer-proof, and built for boulevards and dry slopes. Not a fit if the spot is shady or boggy — it flops in shade and dislikes constantly wet ground.
