I often get asked to recommend Xeriscape plants for Colorado landscapes. This is a difficult task because there are so many to chose from, and I would hate to limit anyone’s pallette to a limited number. After all, it is the variety in color, textures, and form that makes Xeriscaping so attractive.
That being said, I do think a small list can be helpful to people who are new to the area, or are not familiar with the available plant choices and may be overwhelmed by a catalog of thousands of plants. Although this is a Colorado list, most of these plants can be used in many places throughout the world depending on the local climate.
- Fernbush – Chamaebatiaria millefolium Fernbush is a medium sized shrub with interesting fern-like leaves that persist throughout the winter. This shrub requires little water or maintenance, and produces clusters of small white flowers in the late spring through early summer.
- Agastache – Agastache ssp. Agastache, or hummingbird mint, is a fragrant group of colorful perennial herbs that is available in many colors mostly ranging from orange to pink. The plants are covered with beautiful tubular flowers from mid-summer to fall. Hummingbirds absolutely love these plants. (more…)

Panchito Manzanita is one of my favorite plants- and not just because the name is so fun to say. What sets this plant apart is that it’s: 1) low-growing, 2) evergreen , and 3) it can handle full sun and minimal watering. That combination can be difficult to find outside of the standard limited options like the low-growing junipers.
As we convert more lawn areas into Xeriscape to save water, I think the use of evergreen plants is a vital design element to help replace some of the green color of the replaced lawn that is lost. Panchito Manzanita is an excellent choice because it looks great year-round, stays fairly compact, and requires little maintenance.
PLANT STATS
Scientific Name: Arctostaphylos x coloradoensis
Plant Type: Evergreen Shrub
Mature Height: 12-24″
Mature Spread: 18″-48″ (quite variable, depending on conditions)
Water Requirement: Low- may need more water the first growing season, but requires little water once established.
Exposure: Full Sun to very light shade
Best Features: Unique evergreen foliage consisting of leathery 1″ long leaves. This plant really looks great year-round.
Flowers: Small urn-shaped pink to white flowers from February to April
Winter Interest: Very attractive evergreen foliage, reddish colored stems and bark
Disadvantages: Slow grower the first season or two
Availability and Sizes: I have been told that this plant is quite difficult to propagate- therefor It can be a little hard to find. As it gains more popularity and demand for it goes up, it should be available in larger quantities. Usually it is sold in 1 gallon size containers. Since it is slow-growing, a 5 gallon size shrub would be even better.
Maintenance Tip: A low maintenance plant. You may want to prune a branch or two here or there.
Other: Named to Plant Select in 2006. Do not confuse with Arctostaphylos uva-ursi, which prefers much more moisture and shade.

Vermilion Bluffs Mexican Sage is a large-sized flowering perennial that is a real attention-grabber. I have found this plant to be an excellent choice for dry, southern exposures and Xeriscapes. It is fairly easy to grow, and produces bright-red flowers throughout the summer. Hummingbirds love this plant- it is not uncommon to see 4 or 5 of them at a time on a single plant.
PLANT STATS
Scientific Name: Salvia darcyi ‘Pscarl’
Plant Type: Perennial
Mature Height: 36-48″
Mature Spread: 30-42″
Water Requirement: Low
Exposure: Full Sun to partial shade- best in full sun.
Best Features: Intense cardinal red flowers that hummingbirds love.
Flowers: Bright cardinal red tubular flowers from July through October.
Winter Interest: Minimal
Disadvantages: Does not perform well in poorly drained soils. Late to emerge in spring.
Availability and Sizes: This plant was introduced in 2007, but is already available through most retail and wholesale nurseries. Commonly available in 1 gallon size, or in flats of smaller pots. I would recommend the 1 gallon size.
Maintenance Tip: Mulch heavily over the winter to protect from hard freezes.
Other: Leaves and stems are very aromatic. Salvia darcyi was originally collected in the Sierra Madre Oriental in Mexico. Named to Plant Select in 2007.

Diabolo Ninebark is a large, drought tolerant deciduous shrub with intense reddish-purple color. Ninebark has been around for a while but I had not used it before in any of my designs or in my own garden. Thanks to Stefan at Arbor Valley Nursery for recommending this versatile plant!
I was looking for a large shrub that would provide screening along the inside of an open-rail fence. I wanted something that could handle the full sun and dry conditions, and that would get large enough to provide the screening that the client desired. Mountain Mahogany (Cercocarpus ledifolius) was my first choice, but in a 5 gallon size it was very small and spindly, and it is a slow grower- my client wanted some impact right way (note the size in the photo). Diabolo Ninebark provided the perfect solution.
PLANT STATS
Scientific Name: Physocarpus opulifolius ‘Diabolo’
Plant Type: Deciduous Shrub
Mature Height: 6-8′
Mature Spread: 6-8′
Water Requirement: Low
Exposure: Sun (will handle part shade, but is said to have the best color in full sun).
Best Features: Intense foliage color.
Flowers: Clusters of creamy white flowers in mid summer.
Winter Interest: Limited. Bark tends to peel, which can be interesting.
Disadvantages: None known to me.
Availability and Sizes: Readily available for retail and wholesale purchase. Typically found in a 5 gallon container size.
Other: I think this plant would be a great replacement for Purple Leaf Plum, which requires more water, is susceptible to disease problems, and (in my opinion) is somewhat overused.
