Plant of the Month – July

Butterfly Bush

Buddleja davidii 
  • Violet-purple flower spikes provide spectacular summer color and attract butterflies and hummingbirds into the garden.

    Violet-purple flower spikes provide spectacular summer color and attract butterflies and hummingbirds into the garden.

    Plant Form: Deciduous shrub

  • Water Use: Low, Moderate
  • Mature Size: 6-8 ft. tall x 4-6 ft. wide
  • Exposure: Full Sun, Part Sun
  • Bloom Time: Summer (June – August), Fall (September – November)
  • Native to: Asia
  • Hardiness: Cold hardy to -20°F


Butterfly Bush is valued for its showy flowers in summer and fall, when most other shrubs are done blooming. Fragrant purple flowers grow in spikes from July to October on long, arching stems of this tough, bushy, fast-growing shrub. This prolific nectar plant attracts hordes of adult butterflies, but gardeners hoping to provide habitat for these winged jewels also need to install host plants that their larvae rely on to grow into new butterflies, such as milkweeds (butterfly larvae cannot survive on Butterfly Bush). While Butterfly Bush can be invasive in wetter parts of North America, it does not appear to spread in desert areas. Prune back hard in late winter or spring to stimulate vigorous new growth, maintain better shape, and produce superior flowering. Use as a background planting, specimen, or in containers in butterfly and hummingbird gardens, and in cottage or Mediterranean gardens. New compact cultivars are available for smaller gardens and borders.

Plant of the Month – June

For a dramatic statement in your landscape that takes very little water or maintenance, Desert Spoon offers a reliable option…either as a single accent or as a stunning mass planting.

Desert Spoon

Dasylirion wheeleri
  • Plant Form: Cactus/Succulent
  • Water Use: Low
  • Mature Size: 4-6 ft. tall & wide
  • Exposure: Full Sun
  • Bloom Time: Late Spring (May) – Summer (June – August)
  • Native to: Arizona, New Mexico, Texas, northern Mexico
  • Hardiness: Cold hardy to 0°F


Desert Spoon is beloved as an architectural workhorse in desert landscapes. This yucca-like plant has hundreds of long, narrow leaves edged with small, sharp teeth (so plant away from walkways and patios), each leaf starting from a spoon-shaped base, hence its name. Rosettes of younger plants are stemless, but older plants may develop a trunk up to 6 feet tall. Desert Spoon has both male and female plants, with flowering stalks up to 12 feet tall producing thousands of either male or female flowers. Both attract crowds of eager pollinators, including native bees, flies, wasps, and butterflies. Desert Spoons don’t flower every year, but happily, they do not die after flowering like many of their relatives. Dead leaves can be removed for a look reminiscent of pineapple, or left for a more natural-looking trunk. Dramatic as an accent in rock gardens or in large containers. Stunning if mass planted in larger landscapes.

Plant of the Month – May

Large, eye-catching flowers adorn this carefree shrub that performs impressively in extreme conditions with almost no maintenance, taking drought, poor soil, wind, and heat in stride.

Bicolor Rock Rose

Cistus x cyprius var. ellipticus f. bicolor
  • Plant Form: Evergreen shrub
  • Water Use: Low
  • Mature Size: 3-4 ft. tall x 4-7 ft. wide
  • Exposure: Full Sun, Part Sun
  • Bloom Time: Late Spring (April-May), Summer (June – August)
  • Native to: Mediterranean region
  • Hardiness: Cold hardy to 15°F


Bicolor Rock Rose looks so elegant in bloom that it may fool you with its sturdy, easy-care nature. This rock rose tolerates drought, poor soil, drying winds, and desert heat. Clusters of large, white, crepe-like flowers with golden “eyes” and five burgundy spots cover this evergreen shrub from late spring to summer. Although each flower lasts only one day, buds are so abundant that bushes produce an endless procession of color for two or three months. This low-maintenance plant is best pruned in late winter after threat of frost has passed. Its growth habit of being both upright and widely sprawling make it ideal for use on dry slopes as a groundcover, as well as for borders and low hedges. Charming in both Mediterranean-style gardens and cottage gardens. Adds evergreen beauty to rock gardens, and performs great in containers.

Golden Barrel Cactus

Echinocactus grusonii 

Everything about this plant makes it a desert gardener’s delight: extreme drought-tolerance, very low maintenance, suitability for both formal and casual landscapes, attractive clumping habit, and glowing spines for added interest.

  • Plant Form: Cactus/succulent
  • Water Use: Very Low
  • Mature Size: 1.5 ft. tall & 2 ft. wide (3 ft. tall and wide in very old plants)
  • Exposure: Full Sun, Part Sun
  • Bloom Time: Spring (Mar-May), Summer (June – August)
  • Native to: Central Mexico
  • Hardiness: Cold hardy to 18°F


Golden Barrel Cactus is one of the most popular cacti in cultivation today—one look, and you’ll know why. Bright golden spines line the ribs of this spherical cactus, which lights up in the sun. Older specimens produce offsets around their base, eventually forming large clusters with dozens of individual heads. Yellow flowers form late spring to summer in a ring at the top of the plant on larger, mature plants only, peeking out of the dense patch of white woolly hair that protects the top of the barrel. Planted in mass, these whimsical plants create a dramatic effect, even giving the illusion of rolling hills in a flat landscape. Golden Barrels keep getting more beautiful as they grow, needing very little care or water, and usually only suffer if they get not enough sun or too much irrigation. Plant groups close together among large rocks for impact. Wonderful in containers on sunny porches and in atriums.

Spanish Lavender

Lavandula stoechas

Spanish Lavender offers a trio of qualities that gardeners seek: beautiful blossoms, drought tolerance, and fragrant foliage. Add to that rabbit resistance and tolerant of heat, cold, and poor soils, and you have a real winner!

  • Plant Form: Evergreen perennial
  • Water Use: Low
  • Mature Size: 24 – 30 in. tall & wide
  • Exposure: Full Sun
  • Bloom Time: Spring (Feb-May), Summer (June – August)
  • Native to: Mediterranean region and North Africa
  • Hardiness: Cold hardy to 15°F


Spanish Lavender can fulfill your desire for a durable evergreen plant with bright flowers, enchanting fragrance, drought resistance, and heat tolerance. Both flowers and foliage are wonderfully fragrant. Purple bracts on flower heads appear like rabbit ears, and lend a whimsical look. Spanish Lavender is probably the same plant that the ancient Greeks and Romans used to scent their bath water, and is still popular today for dried aromatics and cut stems in homes. Prune lightly after flowering to stimulate next season’s growth. This water-wise, easy-care plant is perfect in both formal and casual Mediterranean-style gardens, as well as in cottage and wild gardens. It also performs superbly on dry slopes and rocky outcrops. Spanish Lavender attracts butterflies and pollinators, but luckily repels rabbits. Beautiful in large artistic pots, mixed borders, mass plantings, and rock gardens.

Trailing Indigo Bush

Dalea greggii

Trailing Indigo Bush is one of the toughest groundcovers available, resisting drought, heat, and rabbits, while offering soil stabilization on slopes and a durable cover in rock gardens and medians.

  • Plant Form: Evergreen groundcover
  • Water Use: Low
  • Mature Size: 1-2 ft. tall & 3-9 ft. wide
  • Exposure: Full Sun
  • Bloom Time: Spring (Feb-May), Summer (June – August)
  • Native to: New Mexico, Texas, Mexico
  • Hardiness: Cold hardy to 10°F


Trailing Indigo Bush creates a mounding, low-maintenance, easily established groundcover for any arid location. Silvery blue-green foliage adorns this spreading plant that roots at the nodes of long, trailing stems, covering everything in its path and making it especially useful to stabilize slopes. Its tiny, purple, pea-like flowers are not showy from a distance, but butterflies, native pollinators, and humans appreciate their beauty close-up. This durable groundcover shuns fertilizer and overwatering, but some watering in summer helps keep the foliage full. In the late winter or early spring, cut off the stems of last season’s growth to stimulate new growth in spring. Besides being tolerant of drought and reflected sun, Trailing Indigo Bush is happily rabbit resistant. One of the toughest groundcovers available, it is valued on slopes, medians, in rock gardens, and wherever soil stabilization is needed.
