Medium Water

Mature Size: 24”X 24”
Blooming Season: July-September

Tubular, raspber- ry-pink flowers make Giant Hys- sop a favorite of New Mexico’s gardeners and hummingbirds. The flowers are prolific and con- tinue through the fall. Native to the moun- tainous areas of southern New Mexico and western Texas, Agastache cana does well in average garden conditions, mixing well with other late-blooming perennials. It’s cold hardy to -20˚ F and also remark- ably heat tolerant as long as it gets adequate water.

Greek Yarrow, Achillea ageratifolia

Full Sun, Part Shade
Low Water

Mature Size: 6”X 12” Blooming Season: Late Spring Flower Color: White

This slow-growing little plant is equally at home in the rock garden or perennial border when used as a groundcover or edging plant. Greek Yarrow is a reliably heavy bloomer, covering itself with bright white clusters of tiny flowers for many weeks in late spring. The dense gray-green foliage is tidy and evergreen (particularly in milder climates), which gives the plant season-long interest.

Full Sun, Part Shade
Low Water

Mature Size: 12’X 10’
Blooming Season: Summer
Flower Color: White

Arizona Rosewood is a handsome large shrub at its best in open windy spaces where evergreen wind protection is especially welcome. Extreme exposures seem to increase its density and, unlike most broadleaf evergreens, its foliage stays crisp and attractive through heat and cold. Lacy umbels of small white flowers crown Rosewood in summer, turning a deep cocoa brown and persisting well into winter. This is a useful native rose with no off season.

Full Sun, Part Shade
Low Water

Mature Size: 6’X 6’
Blooming Season: Summer

Known primarily as an evergreen shrub, Rosemary is a bushy plant featuring stiff upright stems and soft blue flowers in summer. Rosemary officinalis “Arp” has proven itself to be a cold hardy selection, extending its use into New Mexico’s higher elevations. A great choice for hot walls and corners and other areas that get intense reflected heat. Plant in combination with other heat-loving plants like Zauschneria californica (Hummingbird Plant), Lavandula and Calylophus (Sundrops).

Cowania Cliffrose, Purshia syn

Full Sun, Part Shade
Low Water

Mature Size: 8’X 6’
Blooming Season: Summer
Flower Color: Yellow

Cliffrose makes an excellent companion for perennials because its open-branched form casts light shade. Its irregular shape lends a native touch to landscapes which is appropriate since this plant is a New Mexico native. Fragrant flowers cover the branches in early summer, a few of which remain virtually all summer long. Feathery plumes form in mid-summer and persist into winter (consequently, Cliffrose is often mistaken for Apache Plume). It can handle the hottest south- and west-facing garden locations.
