Native plants from the Western shortgrass prairie (Zone 6a) — Humid continental (hot summer) climate
Why Cottage/English Gardens in Arvada?
Arvada has the houses for a cottage garden even if it does not have the English rain. The older streets around Olde Town Arvada and Grandview Avenue are full of small early 1900s homes, bungalows and narrow frontages, exactly the scale where a picket fence, a gate arbor and a deep flowering border look intended rather than overgrown. East of Wadsworth the post-war brick ranches have long, low fronts that a three-layer border softens completely, and out in Ralston Valley and the newer Candelas and Leyden Rock subdivisions the two-story houses sit on lots where a cottage-style front bed is the quickest way to make a builder home look like it belongs to someone.
The look survives here; the English plant list does not. Arvada sits at about 5,300 feet in USDA Zone 6a, which means winter lows of -10 to -5°F, intense high-altitude sun, drying chinook winds and wet spring snow that lands after bud break. Denver's official normal is 14.48 inches of precipitation a year, roughly a third of what a Kent garden gets, so the soft, thirsty regulars need swapping for Front Range equivalents. Instead of tender ramblers, put Rosa 'William Baffin' or Rosa 'John Cabot' on the arbor; instead of Lavandula angustifolia 'Hidcote' in heavy clay, use Lavandula × intermedia 'Phenomenal' in a raised, gritty bed. Nepeta × faassenii 'Walker's Low', Salvia nemorosa 'May Night', Penstemon × mexicali 'Red Rocks' and Agastache 'Blue Fortune' give the same blue and pink haze as an English border on a fraction of the water, and true Delphinium elatum should be treated as a short-lived treat rather than the backbone.
The soil needs work too. Most Arvada yards sit on alkaline clay loam with a pH around 7.5 to 8.2 and very little organic matter, and builders often left only a skim of topsoil over compacted fill. That pH suits lilac, Paeonia, Alcea rosea, Achillea and Nepeta perfectly, but it yellows hydrangeas and acid lovers with iron chlorosis, so leave those out. Work three to four inches of plant-based compost into the top six to eight inches of every border, or better, raise the rose and lavender beds four to six inches behind a stone or steel edge so the crowns never sit in March meltwater.
Water rules shape the layout. Arvada declared Stage 1 drought restrictions effective April 15, 2026: lawns get two assigned days a week, and no outdoor watering is allowed between 10 a.m. and 6 p.m., while trees, shrubs, gardens and flowers may still be watered any day by hand or by drip outside those hours. That favors the cottage style over a big lawn: put the borders on drip, shrink the turf to a tidy panel, and let the flowers carry the picture. Arvada water customers can also buy discounted Garden In A Box kits through Resource Central in the spring and late-summer ordering windows, an easy way to fill the outer border with Colorado-tested perennials.
4 Cottage/English Design Ideas for Arvada

The Olde Town Picket Fence Border
$18–38/sqftA white picket fence runs the frontage of a narrow early 1900s house near Grandview Avenue, with a cedar arbor over the gate carrying a red Canadian Explorer climber. Behind the fence a raised border, edged in Lyons sandstone, steps from tall hollyhocks at the porch down to catmint spilling onto a brick walk. The bed faces south to the street, so it takes full sun all day and the climber gets the morning light that keeps its leaves clean.

The Ranch House Lavender Ribbon
$16–32/sqftA 1960s brick ranch east of Wadsworth gets a curving flagstone path from the driveway to the front door, with the old foundation shrubs pulled out and replaced by a three-layer border. Lavender and catmint form a continuous ribbon along the path, shrub roses and lilac fill the middle, and a crabapple at the corner throws afternoon shade over the west end. The lawn shrinks to a single oval, which keeps the house inside the two-day lawn schedule while the border runs on its own drip zone.

The Rose Arch Back Garden
$22–45/sqftBehind a two-story Ralston Valley house, a painted steel rose arch frames a brick path that runs from the patio to a small round seating circle at the back fence. The borders on either side are deep enough for three layers: tall Agastache and penstemon at the back, roses and peonies in the middle, and lady's mantle and cranesbill at the front edge. The patio faces west, so a honeylocust planted at the corner shades the table through the hottest summer evenings.

The Covenant-Friendly Cottage Front
$14–30/sqftA newer Candelas or Leyden Rock home gets a cottage front that still reads neat enough for an architectural review committee: a low stone wall, a crisp gravel strip along the sidewalk, and a deep planted bed filled with long-blooming, water-wise perennials. Pink and blue drifts repeat in groups of five so the bed looks designed from the street, and a single serviceberry gives spring flowers and a bit of height near the entry. The bed faces east, so morning sun reaches it early and the hottest afternoon light falls on the house instead.

Limited bloomsDesign Tips for Arvada (Zone 6a)
- Raise the rose and lavender beds four to six inches behind a stone or steel edge: Arvada's alkaline clay holds March meltwater around the crowns, and wet crowns kill more Lavandula and roses here than -10°F ever does
- Pick cottage plants that like pH 7.5 to 8.2: lilac, peony, hollyhock, Nepeta and Achillea thrive, while Hydrangea macrophylla and other acid lovers yellow with iron chlorosis and never look right
- Put every border on its own drip zone so it can run any day outside 10 a.m. to 6 p.m., while the lawn sticks to its two assigned days under Arvada's Stage 1 rules
- Use Canadian Explorer climbers such as Rosa 'William Baffin' on arbors, and keep brittle wood off structures: wet April and May snow lands after bud break and snaps tender canes
- Order discounted Garden In A Box kits through Resource Central in the March or June window if you are an Arvada water customer, and use them to fill the outer border with Colorado-tested perennials
- Shade the west side of any seating area with a honeylocust or crabapple: high-altitude sun and a west-facing patio make July evenings hot, and soft cottage foliage scorches without it
- Mulch three inches deep with shredded cedar and top it up each spring, but use pea gravel around lavender and penstemon so their crowns stay dry

Native ecoregionFrequently Asked Questions
How much does a cottage garden cost in Arvada, CO?
As a rough Denver metro guide, landscape crews commonly bill about $60–90 per hour per worker, and a planted front cottage border on a 400–700 sqft Arvada frontage runs about $8,000–24,000 installed, including sod removal, compost, drip and plants. A cedar picket fence with a gate arbor adds $3,500–9,000, and a clay brick or flagstone walk usually lands at $25–45 per square foot. A full back garden with a brick path, rose arch, seating circle and deep borders is commonly $30,000–75,000. Buying Nepeta 'Walker's Low' and Lavandula × intermedia 'Phenomenal' in one-gallon pots and planting them yourself can bring a border under $10 per square foot.
Which roses survive an Arvada winter?
Own-root, cold-hardy shrub and climbing roses. Zone 6a lows of -10 to -5°F are not the main problem; the dry chinook wind, strong sun and late wet snow are. Rosa 'William Baffin' and Rosa 'John Cabot' from the Canadian Explorer series are the reliable arbor climbers, while Rosa 'Therese Bugnet', Rosa 'Morden Blush' and Rosa 'Hope for Humanity' carry the shrub layer. Grafted hybrid teas often die back to the graft. Plant the graft or crown two inches below the soil, water deeply in dry winter months when the ground is not frozen, and leave pruning until the forsythia blooms in spring.
Is a cottage garden low maintenance in Arvada's climate?
Lower than a lawn, if you choose the right plants. Nepeta 'Walker's Low', Salvia 'May Night', Penstemon 'Red Rocks' and Achillea 'Moonshine' need a shear after their first bloom and one cutback in early spring, and that is most of the work. Leave last year's stems standing until late March, because they catch snow and protect the crowns. Budget for checking the drip lines each April, topping up three inches of mulch, and staking hollyhocks and peonies before the hail season.
When is the best time to plant a cottage garden in Arvada?
Late April through early June, and again from late August through September. The median last spring freeze at Denver International Airport is around May 5 and the median first fall freeze around October 9, so tender annuals wait until after Mother's Day. Roses, lilacs and shrubs establish best in September, when the soil is still warm and the plant is not fighting July heat. Keep frost cloth ready: wet May snow is common on the Front Range.
What are Arvada's watering rules for gardens?
Under the Stage 1 drought restrictions that took effect April 15, 2026, single-family homes water lawns on two assigned days: even-numbered addresses on Sunday and Thursday, odd-numbered addresses on Wednesday and Saturday. Nobody waters outdoors between 10 a.m. and 6 p.m. Trees, shrubs, gardens and flowers can be watered any day with a hand-held hose or drip, outside those hours. The city may keep the restrictions in place for a full year and adjust them, so check the City of Arvada water restrictions page before planning a new lawn.
Do I need HOA approval or a permit for a cottage garden?
In covenant neighborhoods such as Candelas and Leyden Rock, assume yes for the HOA: submit a simple plan with the bed shapes, fence style, edging and plant list before work starts. Colorado law does not let an HOA ban drought-tolerant landscaping outright, but it can set reasonable design standards. For fences, arbors and pergolas, check height limits and whether footings need a permit and inspection with Arvada Building Services, which can also confirm the required frost depth for posts.
How do I protect a cottage border from Arvada hail?
Hail season on the Front Range usually runs from mid-May into August, and the soft, tall cottage plants are the first casualties. Plant Alcea rosea, Paeonia and Delphinium in groups so they hold each other up, stake them early, and site them where the house eave or a tree canopy takes the first hit. Most perennials recover if you cut shredded stems back hard; roses usually push new growth within three weeks.
