Hyacinths are a much loved and very fragrant spring bulb, flowering in March and early April in our area. Clusters of bell-like flowers dangle from a central stem. Native to Asia, hyacinths were one of the early favored flowers by the Persians, Turks and Europeans, in fact, practically everyone who came in contact with them. Easy to grow in full sun to part shade in average garden soil. Hyacinths come in many pastel colors, both single and double flowers.
Remarkable old Bourbon rose dating to 1868. Remarkable for fragrance and bright cerise pink flowers, and best of all, thornless canes -- it's people friendly! Not strictly a climber, but a mannerly climber.
Zephirin Drouhin is planted in a low water-use location.
Utah serviceberry is a quite beautiful shrub extending from the Southwestern states northward throughout the Rocky Mountains and through various ecosystems between 4000 and 8000 ft in elevation. Deep green leaves, large oval shaped and toothed at the margins, many intricately branched, smooth gray to maroon bark. Large white flowers with five widely spaced petals open in May and June. Berries appear in the summer, ripening to pink, then red, then finally dark blue. Leaves turn red and orange in the fall.
Golden sulfur buckwheat is one of those plants you'll come across while hiking in the West and wonder why it isn't in your garden, its so adorable!
The leaves are gray-green, spatula shaped and woolly underneath, to about 2-3 inches. They form a rosette at the base. In early spring, tall, stout stems extend upward up to 2-3 feet. The bright golden flowers are nearly luminescent, appearing first as ball-like umbels (clusters), then each ball opening up to a circle of golden flowers. As the flowers age, then turn orange.
Our native skullcap is one that should be included in every drought tolerant landscape, short lived though it is. This is the kind of garden-worthy plant we all desire, neat, compact and all season blooming with no maintenance to speak of. You just can't go wrong as long as your soil has decent drainage. It reseeds some, but to me, this is just a bonus.

Low growing, drought tolerant evergreen groundcover that becomes covered in tiny sky blue flowers in early spring for about 6 weeks, then sporadically throughout the year. I’ve seen a few twinkling blue blooms in every month of the year. The tiny leaves of V. pectinata are gray-green and tomentose. Allow plenty of room for the spread of this fabulous groundcover; it’ll just keep going and going and going. And you won’t want it to stop.
Mountain mahogany is native to the Texas Panhandle and throughout the Southwest, found in elevations from 3000-9500 ft. Another common name is Alderleaf mountain mahogany, because its leaves resemble that of an alder. Mountain mahogany, whose wood is very hard (Palo Duro) is found in Palo Duro Canyon. Extremely drought tolerant, it will survive on 10 inches of rainfall. An aromatic shrub with shredding reddish bark, but can grow to tree size. Mountain mahogany's flowers are small, rayless and insignificant, as they are in the other species.
Native evergreen shrub that makes an excellent hedge plant and wind break. Its blue-green prickly leaves keep the unwanted out (to a point). Please allow room for its spread.
A habitat plant for shelter and as a food source of food for birds and other wildlife that is an attractive addition to the home landscape, where an evergreen shrub is called for in a sunny spot. Sun yellow flowers in March. Cold hardy to -20°, algerita can be found growing from 4000 to 7000 ft. in elevation in Texas, the southwest and Mexico.
Cliff fendlerbush is another Texas and Southwest native shrub too little used in the xeric landscape. Springtime lifts the cliff fendlerbush above the ordinary into prominence in the landscape. It is said the ravines and arroyos look dotted with snow from a distance, so profuse are the fragrant, creamy white, sometimes with a pink tinge, four petaled flowers in May and June. It's natural element is rocky arroyos (rupicola=rock dweller), cliff ledges and limestone soils with good drainage that average 12-18 inches of moisture with hot sunny days.
Veronica x ‘Blue Reflection’ should be an indispensable evergreen groundcover for you, as it has become for me.
New Mexican privet can be viewed either as a tall shrub or smaller tree. New Mexican privet will flower (tiny yellow) before leafing out with small oval glossy green leaves to be followed with black berries in the fall. Heat and drought tolerant will live in most soils and water-use areas. Attractive taller plant for the home landscape, similar to the yaupon holly in form.
There are many different sedum species and varieties of this delightful spreading groundcover. I took this picture on a garden tour in Angel Fire New Mexico, and have not been able to identify it yet. It is easy to see from the picture how it got its common name, stonecrop. Sedum groundcovers spread nicely in a low to medium water use area of gritty, well drained soil, and will do just fine in afternoon shade.
Yaupon holly is a tall shrub or a small tree growing typically to 8-12 feet in the Texas Panhandle. Cold hardy to Zone 7 (still best to plant in a protected location), it prefers partial shade, especially afternoon shade. Low (once established) to high water use. Small leathery, glossy, evergreen, dark green leaves (to 1.5” long) have toothed margins on dense branching. Insignificant greenish white flowers in springtime followed by red berries in the fall. Female plants require a male plant to pollinate and bear fruit (dioecious). Attractive tall, traditional looking shrub.
