The plants that look best in Arizona yards year-round get their appeal from foliage color and form. Agave, desert spoon, red yucca, cenizo, purple prickly pear and blue palo verde hold up through 110°F summers and light winter frost.
Key takeaways
- Choose plants for leaf color and shape. Agave, desert spoon, cenizo and red yucca keep both through summer highs above 110°F.
- Space every plant at its mature width, from about 2 to 4 feet for Parry’s agave to 20 to 30 feet for blue palo verde.
- Plant in October and November so roots establish before summer. March and April planting works with extra watering.
- Once established, water deeply and rarely, roughly every 2 to 4 weeks in summer and less in winter.
- Limit each bed to two or three foliage colors and mix coarse, medium and fine textures.
What makes a plant look good in every season in the low desert?
A plant looks good year-round when it keeps its leaves, holds a clear shape and has a color or texture you can pick out from the street. Flowers add a few weeks of color at best, so the plants below earn their place with foliage, bark and form.
Conditions in Queen Creek narrow the field. Soil is alkaline and often sits on caliche, irrigation water is hard, and summer highs pass 110°F. Plants that handle all three without leaf scorch or yellowing still look good in August, when little else is blooming. You can browse our plants department for more options that suit these conditions.
Which plants look best year-round in Arizona yards?
Six plants stand out for foliage, form or bark that stays attractive in every season. These are varieties we commonly carry, and availability changes week to week and season to season, so check with us before planning a bed around one. Each has a drawback.
Agave parryi (Parry’s agave)
Parry’s agave forms a tight rosette of silver-blue leaves tipped with dark spines, and it looks the same in January as in July. Mature size is roughly 2 to 3 feet tall and 2 to 4 feet wide. It wants full sun and well-drained soil, and once established it needs a deep soak about every 2 to 4 weeks in summer and much less in winter.
The drawback is the sharp spine on every leaf tip. For a bigger statement, Agave americana reaches about 6 feet tall and 8 to 10 feet wide, so it needs a large, open bed well away from walkways.
Dasylirion wheeleri (desert spoon)
Desert spoon makes a rounded fountain of narrow, blue-green to gray-green leaves, and old plants build a short trunk over many years. It reaches about 3 to 5 feet tall and wide in full sun, and it handles heat reflected off block walls and driveways. Established plants do well with a deep watering every 3 to 4 weeks in summer.
The drawback is the row of small hooked teeth along each leaf edge, which snag skin and clothing.
Opuntia santa-rita (purple prickly pear)
Purple prickly pear has flat, rounded pads that turn violet-purple, deepest in cool, dry weather. Expect 4 to 6 feet tall and wide in full sun, with yellow blooms in spring. Established plants need little water beyond rain, perhaps a deep soak about once a month in summer.
The drawback is the fine, hair-like glochids around each spine cluster, which irritate skin, and the purple fades toward green in shade or with frequent watering.
Hesperaloe parviflora (red yucca)
Red yucca grows as an arching clump of narrow, dark green leaves with thin white threads curling along the edges. The clump reaches about 3 to 4 feet tall and wide. Flower stalks rise to 4 to 5 feet in spring and early summer, carrying coral-pink blooms that hummingbirds visit.
Full sun to light afternoon shade suits it, with a deep watering every 2 to 4 weeks in summer once established. The drawback is the dried flower stalks, which look untidy until you cut them to the base.
Leucophyllum frutescens (cenizo, or Texas sage)
Cenizo is a rounded evergreen shrub with soft silver-gray leaves that brighten in full sun. Most reach about 5 to 8 feet tall and wide, and named selections stay smaller. It needs fast-draining soil and a deep soak every 2 to 4 weeks in summer once established. Purple flowers often follow summer humidity or rain.
The drawback is its dislike of wet soil and heavy shearing. Overwatering causes decline, and clipping it into a ball removes the natural shape.
Parkinsonia florida (blue palo verde)
Blue palo verde is a desert tree with blue-green bark that photosynthesizes, so the branching stays green even when the tree drops its small leaves. It grows about 20 to 30 feet tall and wide in full sun and covers itself in yellow flowers in spring, usually April. Established trees need a deep soak about once a month in summer.
The drawback is litter. Petals, leaflets and twigs fall onto pavers and pools, and young trees can be damaged by hard frost. See our desert trees for other shade options.
How do I combine these plants so the yard looks layered?
Pair one coarse, sculptural plant with medium and fine textures around it. Agave, desert spoon and purple prickly pear are coarse, cenizo is medium, and the narrow leaves of red yucca read as fine. A single agave surrounded by red yucca and cenizo gives you three textures and two or three foliage colors in one bed.
Limit each bed to two or three foliage colors, such as blue-gray, silver and dark green, and repeat them. Repetition matters. Leave open space of decomposed granite or flagstone between plants so each shape reads clearly, and space every plant at its full mature width, because a crowded bed loses the shapes that make it work.
When is the best time to plant them?
October and November are the best months, because roots establish through the mild winter before summer heat arrives. Spring planting in March and April also works if you water through the first summer. Avoid June through August, when 110°F air and hot soil stress new roots.
Our gardening calendars show month-by-month planting windows for the East Valley. Young palo verde and agave planted in fall can show frost damage in their first winter, so keep frost cloth on hand.
How much water do these plants need once established?
Established plants need deep, infrequent watering, roughly every 2 to 4 weeks in summer and every 4 to 8 weeks in winter, depending on soil and exposure. Soak the whole root zone, then let the soil dry before the next watering. Frequent shallow watering keeps roots near the surface and encourages rot in agave, prickly pear and cenizo.
New plants need more. Expect to water about weekly for the first few months, then stretch the interval gradually through the first year. Hard water leaves salts near the surface, and a deep soak pushes them below the roots. Before planting, fill the hole with water. If it is still standing after 24 hours, plant on a mound or pick another spot, since caliche can hold water like a bowl.
What mistakes make desert plants look rough?
Overwatering causes most of the trouble, showing up as yellow leaves, soft pads or a collapsed rosette. Shearing is next. Clipping cenizo or palo verde into balls and boxes removes the natural shape you planted them for, so cut dead material at the base and thin crowded branches instead.
Planting too close is the third. A small agave in a nursery pot looks manageable, but it will fill its full width within a few years. Plant by mature size and fill the gaps with annual flowers and foliage while the permanent plants grow. Choosing a plant for its flowers alone is the fourth, because a plant with weak form belongs in a container, not an anchor bed.
Frequently asked questions
Can any of these plants handle partial shade?
Only red yucca tolerates light afternoon shade well. Agave, desert spoon, purple prickly pear and cenizo need full sun for the best color and shape. Too little light stretches cenizo into a loose shrub and turns prickly pear pads greener and thinner. A spot with morning sun and afternoon shade suits red yucca.
Can I grow these plants in containers?
Parry’s agave, desert spoon and red yucca can live in large pots for years if the pot has drainage holes and a gritty, fast-draining mix. Pots dry faster than ground soil, so water more often than the ranges above. Cenizo and blue palo verde do better in the ground. Browse our pottery and planters for wide, heavy containers.
Will winter frost damage these plants?
Established plants here usually come through East Valley winters without damage, but young ones can show frost injury on nights near or below 32°F. Cover them with frost cloth in the evening and remove it in the morning. Wait until spring to prune damaged growth, because the dead tissue shields the healthy tissue below.
How far back should spiny plants sit from a walkway?
Set spiny plants back from a walkway by at least half their mature width plus a foot or two, so leaves never reach a passerby. A desert spoon that grows 4 feet wide, for example, wants roughly 3 to 4 feet of clearance. Check the plant’s full size, not the nursery pot, before choosing the spot.
When should I cut back red yucca flower stalks?
Cut red yucca flower stalks to the base once the blooms fade and the stalks dry and turn brown, usually by late summer or fall. Use sharp loppers and gloves. Leave the leaf fountain untouched, because it gives the plant its winter shape.
Is a foliage-first yard right for you?
A yard built on these plants suits gardeners who want low maintenance, deep-soak watering and a look that holds through August. It will disappoint anyone who wants a lawn, constant flower color or a play area where bare feet and small hands wander near spines. If that describes you, use softer plants near the house and keep these as accents. Stop by our nursery in Queen Creek to see how these plants look in person.
