Posted By High Country Gardens Content Team on Aug 11, 2021 · Revised on Aug 27, 2026

Before and After: A typical kentucky bluegrass lawn is replaced with bright pink penstemon, salvia, groundcovers, and other xeric waterwise plants

When our customers Matthew and Pascale planted their first garden at their home in Boise, Idaho (zone 6b/7a), they went for big impact and major curb appeal! With the goals of saving water and supporting pollinators, Matthew and Pascale removed their entire front yard of traditional Kentucky Bluegrass turf. In its place, they planted bright and colorful flowers, groundcovers, and ornamental grasses, for a new front yard that is filled with personality and interesting details. The results are truly inspiring! Below, Matthew shares their process, three favorite perennials, and his full plant list with us. Read on for details.

What inspired you to plant a waterwise lawn or garden?

M.W.: "When we first moved into our house the front yard was just weedy Kentucky bluegrass and a lone barberry. It's south-facing, sloped, and our irrigation system had failed, so the grass was nearly impossible to keep watered."

"Additionally, we had some work done on the house and the heavy machinery killed a large section of the grass, so it was a good time to make some changes. We wanted to reduce our water consumption, bring in more pollinators, and make better use of the space, since we didn't use the front lawn much at all."

Was this your first time creating a lawn or garden like this, or do you have experience?

M.W.: "Other than vegetables, this was our first time planting a garden. Our soil is heavy clay, and most of the plants we wanted require good drainage, so we brought in landscaping rock and a gritty soil mix and created a series of low berms on top of the clay. It's been a learning experience, finding out what will grow in the native clay and what does better on a berm."

What are your favorite plants?

M.W.: "Mohave Sage (Salvia pachyphylla) has showy flowers, a long blooming season, and the evergreen leaves take on a silvery-blue color in the winter. Creeping Goldenaster (Heterotheca jonesii) is very drought-tolerant, evergreen, blooms for months and months. 'Blonde Ambition' Blue Grama Grass (Bouteloua gracilis) - it's drought-tolerant, clay-tolerant, and seedheads look good through the winter."

Yellow Crocus in sunny garden bed — Underplanting perennials with spring-blooming bulbs, like these Crocus, is a great way to extend the season of color in your garden.

A hummingbird sips nectar from the tubular flowers of Agastache rupestris. — A hummingbird sips nectar from the tubular flowers of Agastache rupestris, also called Licorice Mint Hyssop. This native plant is one of the most durable Agastaches, and highly attractive to pollinators.

Do you have any tips for other waterwise gardeners?

M.W.: "Plan for all seasons, not just summer. The first winter our garden was very bare-looking. Try to anchor your beds with evergreens like agave, yucca, manzanita, or ative salvias, as well as ornamental grasses that have a strong winter presence, like little bluestem or blue grama grass. From there, you can fill in with summer-flowering perennials."

"Additionally, if you have perennials that are later to wake up, like agastache, gaura, and blanketflower, they can be underplanted with early spring-blooming bulbs like crocus, Iris reticulata, or species tulips, since their water needs are similar. For us, this has extended the blooming season from late February through November."

Purple Salvia sylvestris flowers — Spring Garden | The large nectar-rich flower spikes of Salvia sylvestris are highly attractive to bees. We offer several cultivars.
