These plants are an alternative to high maintenance sod when planted in mass in small areas. Think of those hard to mow and water areas like around posts and benches where the mower doesn‘t fit, on slopes and near foundations! The plants we offer compliment each other visually, have the same water needs and soil tolerances—So go a head and mix and match!
'Spicy Orange’ Thyme (Thymus ‘Spicy Orange’)
Massed, small pale pink flowers provide Butterfly food in early summer.Light foot traffic is tolerated and releases strong spicy-orange fragrance from the 2-3”H by 10-12”W evergreen plants with needle-shaped leaves.Plant in Sun.
This dwarf thyme with tiny hairy leaves on tight, mounding mats with tufts of lavender flowers in summer is great for use between steppingstones or as an edging, 2”H by 12”W.
Zone 4 Sun
Persian Stonecress (Aethionema grandiflora Pulchella Group)
Delightful, alkaline soil tolerant dry rock garden plant that blooms in bright, light pink from May to August. Bloom stalks are carried over a 6-8” tall by 12” wide helmet of powdery blue foliage. Full sun, don’t accidentally drown this one by planting in a low spot. Zone 5 but Casper tested.
Plant Select® 2002 Lustrous fuchsia flowers bloom and repeat on this fast spreading South African succulent ground cover. Leaves persisting through winter will remain green and may become tinged with purple. Plants mature to 2” tall by 18” wide.
Zone 4 Full sun

Plant Select® 2009Iridescent lavender flowers with dark eyes bloom on 2-3” tallmats of green foliage that spread from 1-2’wide.This sport of Table Mountain tolerates a wide range of soil conditions.
2009 Plant Select!This Turkish nativeisexcellent in rock gardensas either groundcover or accent plant and useful in other Full Sun dry locations.The evergreen mat of foliage with upturned silvery edges looks like a collection of up-turned horse hooves. This species has been tested for several years on a windy, exposed, west-facing slope in Casper near outer Drive proving its true xeric mature, hardiness and clay tolerance!2-4”H by 24-36”W (at maturity)
A choice, vigorous multi-purpose hardy landscape plant. Whether as a replacement for lawn, as a rock garden accent, or as a garden edging you will like the way this one winters and how it tastes when harvested for culinary use.
Zone 4 Full sun to part sun
Wooly Thyme (Thymus praecox pseudolanuginosus)
Ground hugging cushion of wool-gray foliage, 1 ft diameter, with purple flowers in summer. Tolerates winter exposure better than many thymes. Great for light foot traffic and handles partial shade. A reliable choice for planting rock walls, as it will spill over the edge with the least winter die-back.
Zone 4 Sun to part shade
Veronica x 'Crystal Rivers'
Plant Select® 2003 A wonderful little perennial that has proved itself in Casper through five drought years if you count under its former name before it became Plant Select! One plant forms 4” x 18” mat of glossy dark green foliage with deep blue flowers in summer. This hybrid cross of wooly and Turkish speedwell is better than either parent!
Plant Select® 2007 We’ve used regular culinary winter savory as a hot rock garden accent and groundcover for years. This hardier selection is prostrate growing, evergreen, well covered in purple (vs. white) flowers August to hard freeze and just as useful in the kitchen as the regular culinary herb. While not picky about soil, grow on the dry side in tight clay. Height:4”-6” by 12”-15” wide.
Zone 3b Full sun to partial shade
Sedum Angelina (Sedum rupestre ‘Angelina’)
This Proven Winners’ plant from Croatia really is a winner. Brilliant yellow tipped light green conifer shaped leaves become orange tinged during early and late season growing conditions. The 6-8” tall by up to 12” wide plant is a strong grower and is as tough as nails: successfully over wintering in rock pockets and at the edges of planters left outdoors and ignored. Use this one not only in the traditional sunny dry garden as a groundcover, edging, or accent but also in combination hanging baskets, as planter or barrel edging. Best color develops in full sun.
Zone 3 Full sun
Turkish Veronica (Veronica liwanensis)
Plant Select® 1997 Cobalt blue flowers cover the mat-forming glossy green leaved groundcover in late spring to early summer. Height 1-2” by 12” diameter. Plant this Zone 4 low water groundcover, accent or edging in full to part sun.
Zone 4 Full sun to part sun
Ice plant info: Dryland ground covers, rock garden accents, xeric garden edgings, trough plantings, all are good uses for these. They thrive in low water settings in clay and tolerate more moisture in sharp draining soils. Unlike sedum, they are not a deer or rabbit magnet and can be used on sloping sand for erosion control and around structures as part of a fire resistant landscape. Consider planting these between stepping stones in spots that seem too hot and dry for thymes.
Crystal Rivers and Turkish Veronicas and Hymenoxes scaposa are good companion plants as are the ground covers like Angelina sedum, Silverton Bluemat Penstemon, Purple Winter Savory and Greek Yarrow. Gravel is the preferred mulch around these xeric ground covers for both weed control and decorative interest. Be careful to not apply mulch over or too deeply around plant crowns.
Red Mountain Ice Plant (Delosperma dyeri ‘Psdold’)
Plant Select® 2007 Blazing scarlet flowers form a red carpet atop this 2”tall succulent throughout the growing season. Individual plants will become 15-20” wide making a striking, fire-resistant ground cover for drought tolerant xeric plantings in sand, loam or clay. For best bloom plant in full sun but partial shade is also tolerated.
Plant Select® 2002 Iridescent salmon-pink blooms top this 2” tall succulent that will be an 18” wide groundcover at maturity. Blooms and repeats slightly out of sync with Table Mountain to help extend the season of color on these carpet-like plants.
Plant Select® 1998 This upright clumping succulent produces a dome of bright pink flowers with eye-catching centers on a 4” tall by 10” wide plant. The petals have an almost metallic shimmer. Blooming starts in June and repeats until fall.
Zone 4/5 Full sun
Sedum ewersii var. homophyllum
This 3” Tall 6-8” Wide cultivar blooms in pink for a long part of summer over evergreen diminutive glaucus foliage.The look is delicate and dainty for rockery or border but our experience with another ewersii cultivar is one of tough-as-nails over-winter-in the-pot-outside!
Zone 4 Full sun
Ephedra regeliana
This is a tiny Joint Fir, a prehistoric survivor and rare conifer relative bearing small red cones for rockery, or limited groundcover use.Plant this 3-6” Height by 6” Width blue-green beauty in draining soil in Sun to part Sun.
Zone 4 to Sun to partial sun
Greek Yarrow (Achillea ageratifolia)
Ground hugging 12” diameter circular mats of deeply cut gray-white foliage are topped by 6”-10” tall flower stalks of cheery white blooms in late spring. Makes a good edging in a xeric or well drained garden and an accent in a rock garden. This one will not run!
Zone 3 Full sun

Throughout this site, the following are used as guidelines for watering established plants:
These plants need regular watering somewhat like a bluegrass lawn so that they never dry to depth in the root system during the active growing season and need occasional winter watering to prevent root dessication and resultant plant death.
These plants are adapted to intermittent deep watering with soil drying to a depth of a few inches between waterings. Watering frequency may be every couple of weeks during the active growing season and maybe only one winter watering for optimal care.
These truly xeric plants can live with our 12 inches of natural precipitation and only need a winter watering during a multi-year drought but they will thrive with a monthly watering. Overwatering will kill some of these.
