4 English Cottage Garden Ideas for Ann Arbor, MI | Peonies, Roses and Zone 6a Borders
Native plants from the Southern Great Lakes forests (Zone 6a) — Humid continental (hot summer) climate
Why Cottage/English Gardens in Ann Arbor?
Ann Arbor already has the houses for a cottage garden. The Old West Side, Burns Park, Water Hill and Northside are lined with 1890s to 1920s gable-front farmhouses, foursquares and Arts and Crafts bungalows on narrow lots with front porches close to the sidewalk, which is exactly the scale this style was made for. A 30 foot frontage planted three layers deep reads as generous, not crowded, and a picket fence or a low stone edge fits the street without looking imported. The city also has one of the best cottage plant references in the country on its doorstep: the Peony Garden at Nichols Arboretum, where heirloom Paeonia lactiflora such as 'Festiva Maxima' and 'Sarah Bernhardt' still carry the whole June show.
The climate is kinder to English plants than most of the Midwest, with one hard edge. Zone 6a means planning for winter lows of -10°F to -5°F, and the University of Michigan weather station averages about 38 inches of precipitation a year, spread fairly evenly through the seasons, with roughly 121 days a year below freezing. July is warm and humid, typically in the low to mid 80s °F, which suits peonies, Phlox paniculata 'Jeana', Nepeta × faassenii 'Walker's Low' and Alcea rosea 'Chater's Double' perfectly. The hard edge is roses: tender hybrid teas die back to the snow line most winters, so the climbers here should be the hardy ones, Rosa 'John Cabot' and Rosa 'William Baffin', with Rosa 'New Dawn' only on a sheltered south wall. Lavender works, but choose Lavandula angustifolia 'Munstead' or Lavandula × intermedia 'Phenomenal' and give it a gravelly raised edge, because it is wet winter clay, not cold, that kills it.
Soil is glacial: heavy till loams and clay loams on most of the city, with sandier, faster-draining ground near the Huron River terraces. The clay holds water through March and cracks in August, so build cottage beds up 6 to 8 inches with compost and keep crowns of lavender, Dianthus and roses above grade. pH on the till tends to sit near neutral, which roses, peonies and clematis like, but get a soil test through MSU Extension before liming or adding sulfur. Michigan law also restricts phosphorus on lawns unless a soil test shows a need, so test first and feed the border, not the turf.
Finally, the city has written rules for the strip between sidewalk and curb. Under Chapter 40 of the City Code, as amended by ordinance ORD-25-34 in December 2025, grass in the lawn extension stays at or under 12 inches and other cultivated plants at or under 36 inches of foliage, with flower tops allowed to 42 inches, and anything within 40 feet of a residential corner must stay under 30 inches. Trees and shrubs in the right-of-way need written city permission. So keep the tall Delphinium and hollyhocks inside the fence and let the curb strip be catmint, Geranium 'Rozanne' and low peonies.
4 Cottage/English Design Ideas for Ann Arbor
AI-generated image
The Old West Side Picket Border
$18–38/sqftA white picket fence runs the front of a narrow 1900s gable-front house, with a straight brick walk to a shallow porch and a border three plants deep on both sides. The south-facing front gets full afternoon sun, so roses and hollyhocks go against the fence where they catch it, with catmint spilling onto the walk. The curb strip outside the fence is kept low enough to meet the city's lawn extension height limit.

The Peony Walk
$20–42/sqftA curving flagstone path crosses a Burns Park front yard, edged on both sides by a long row of heirloom peonies backed by phlox and clematis on a low obelisk. The walk faces east, so morning sun dries the peony foliage quickly and keeps botrytis down after June rain. After the peonies finish, phlox and asters carry the border into October.

The Arbor Gate Back Garden
$24–48/sqftA cedar arbor carrying a hardy climbing rose opens from a side yard into a small rectangular back garden behind a bungalow, with a gravel path looping around a central bed. Tall spires sit at the back where they get the full west sun, and the shaded strip under the neighbor's maple is planted with ferns and hostas instead of fighting for roses. A pair of chairs at the end of the gravel loop is the only furniture.

The Fieldstone Wall Cottage Garden
$22–45/sqftA low dry-laid fieldstone wall holds a raised bed along the front of a 1950s Cape Cod on a slight slope, lifting the planting above wet clay and giving lavender and Dianthus the drainage they need. The bed faces south and west, so it bakes in July, and the plant list leans on cottage plants that also cope with heat and the odd dry spell. Native coneflower and bee balm mix with the English classics so the border feeds pollinators through August.

Limited bloomsDesign Tips for Ann Arbor (Zone 6a)
- Raise every bed 6–8 inches over the glacial clay with compost and a little grit; wet March soil kills more lavender, Dianthus and roses in Ann Arbor than a -10°F night does
- Get a soil test from MSU Extension before you lime or fertilize; the till here often sits near neutral pH already, and Michigan restricts phosphorus on lawns without a test showing a need
- Keep tall plants such as Alcea rosea 'Chater's Double' and Delphinium inside the fence: the lawn extension limit is 36 inches of foliage and 42 inches of flower, and 30 inches near corners
- Set arbor and fence posts on footings to the 42 inch frost depth used in Michigan, or frost heave in the clay will tilt them within two winters
- Plant peonies in September with the eyes no deeper than 2 inches, and give them morning sun so foliage dries fast after June storms
- Choose own-root hardy climbers like Rosa 'John Cabot' and 'William Baffin' for arbors; they leaf out from the base again even after a hard winter
- Leave Echinacea, Monarda and aster seedheads standing until March; they feed finches through the winter and catch snow, which looks better than bare mulch for four months

How much does a cottage garden cost in Ann Arbor?
Landscape installers around Ann Arbor commonly bill roughly $60–90 per hour per crew member, so labor is most of the price. A planted front cottage border of 300–500 sqft with soil prep and mulch usually runs $6,000–16,000 installed; add $25–45 per linear foot for a cedar picket fence and $3,000–8,000 for a built arbor on proper footings. A full back garden with paths, arbor and deep borders often lands between $20,000 and $55,000. Doing the planting yourself with one-gallon Nepeta 'Walker's Low', Geranium 'Rozanne' and bare-root peonies brings a border well under $10 per square foot.
Is a cottage garden high maintenance in Ann Arbor's climate?
Less than people fear, if you choose the plants for this climate. Plan on a spring cutback in late March or April, a June stake for Delphinium and peonies, a shear of catmint after its first flush, and fall cleanup that leaves seedheads for birds. Humid Julys bring powdery mildew on old phlox, so plant mildew-resistant Phlox paniculata 'Jeana' or 'David'. Hardy own-root roses like Rosa 'John Cabot' need little more than dead wood pruning, while hybrid teas need winter mounding and spraying and are best skipped.
When is the best time to plant a cottage garden in Ann Arbor?
Late August through early October is the best window for perennials and shrubs: the soil is warm, rain returns, and roots grow before the ground freezes. Peonies should go in during September, with the eyes no more than 2 inches deep or they will not bloom. Spring planting works from mid-May, after frost risk has passed, through June. Avoid planting into dry, cracked clay in late July without watering every few days.
Are there rules for planting the strip between the sidewalk and the street?
Yes. Chapter 40 of the Ann Arbor City Code, amended by ORD-25-34 in December 2025, says the lawn extension must be grass no taller than 12 inches or cultivated plants with foliage no taller than 36 inches, with flower tops allowed to 42 inches as long as views are not blocked. Within the sight triangle, 40 feet back from a residential corner along each curb, plants stay under 30 inches. Trees and shrubs in the right-of-way need the city's written permission, and branches must leave 8 feet of clearance over the sidewalk. If you live in a historic district such as the Old West Side, ask the city about fences and walls visible from the street before you build.
Which cottage plants survive an Ann Arbor winter, and which do not?
Peonies, catmint, phlox, Siberian iris, Alchemilla, hardy geraniums, Monarda and Echinacea all shrug off -10°F. The weak points are tender roses, true English lavender in wet soil and short-lived Delphinium elatum. Use Rosa 'John Cabot', 'William Baffin' or 'Olivia Rose Austin' instead of hybrid teas, Lavandula angustifolia 'Munstead' or Lavandula × intermedia 'Phenomenal' on a raised gravelly edge, and Delphinium 'Magic Fountains' treated as a three-year plant. Rosemary and English wallflowers are annuals here.
Where can I see cottage plants growing in Ann Arbor before I buy?
The Peony Garden at Nichols Arboretum is the place to start in late May and June, when the heirloom Paeonia lactiflora collection, including old cultivars like 'Festiva Maxima', is in flower. Seeing them in bloom tells you which heights and colors suit your border. Walking the Old West Side and Burns Park in June is the other good reference, because many front gardens there are long-established cottage borders on the same clay you have.
