Athel Tamarisk: A Controversial Desert Survivor

If you’ve ever driven through the southwestern United States and noticed those wispy, blue-green trees dotting the desert landscape, chances are you’ve spotted an Athel tamarisk (Tamarix aphylla). This hardy perennial shrub has quite the reputation – both as a drought-busting survivor and as a plant that stirs up considerable debate among gardeners and land managers alike.

What Exactly Is Athel Tamarisk?

Athel tamarisk goes by the botanical name Tamarix aphylla, and you might also see it listed under its synonym Tamarix articulata. This multi-stemmed woody perennial typically grows as a shrub, usually staying under 13-16 feet tall, though it can sometimes stretch taller or develop a more tree-like form depending on growing conditions.

What makes this plant instantly recognizable is its delicate, feathery foliage that ranges from blue-green to gray-green in color. The tiny, scale-like leaves create an almost ethereal texture that sways gracefully in the breeze. During blooming season, the plant produces clusters of small pink to white flowers that attract bees and other pollinators.

Where Does It Come From and Where Does It Grow Now?

Here’s where things get interesting – and a bit complicated. Athel tamarisk isn’t native to North America at all. Originally from North Africa, the Middle East, and parts of Asia, this plant was introduced to the United States and has since made itself quite at home. It now grows wild across Arizona, California, Nevada, Texas, Utah, and Puerto Rico, reproducing on its own without any human help.

The Wetland Flexibility Factor

One of the most fascinating aspects of Athel tamarisk is its relationship with water. Depending on where you are in the country, this plant shows different preferences:

  • In the Arid West and Western Mountains regions: It can thrive in both wetlands and dry areas
  • In the Atlantic and Gulf Coastal Plain, Caribbean, and Great Plains: It usually prefers wetland areas but can adapt to drier spots
  • In Hawaii: It typically grows in non-wetland areas but can tolerate some moisture

The Gardener’s Dilemma: To Plant or Not to Plant?

This is where Athel tamarisk becomes controversial. While this plant is undeniably tough as nails and can solve certain landscaping challenges, its non-native status and aggressive spreading habits raise important questions.

The Good: If you’re dealing with extremely harsh conditions – think blazing sun, poor soil, salt spray, or drought – Athel tamarisk laughs in the face of adversity. It’s practically indestructible once established and can serve as an effective windbreak, erosion control, or privacy screen.

The Concerning: This plant’s superpower of survival can become problematic. In many areas, particularly in the western United States, Athel tamarisk has earned a reputation for spreading aggressively and potentially displacing native vegetation.

Growing Conditions and Care

If you’re in USDA hardiness zones 7-11 and considering this plant despite the concerns, here’s what you need to know:

  • Sun: Full sun is best, though it can tolerate some shade
  • Soil: Extremely adaptable – from poor, rocky soil to clay
  • Water: Drought tolerant once established, but appreciates deep watering during establishment
  • Salt tolerance: Excellent, making it suitable for coastal areas
  • Maintenance: Minimal pruning needed, but keep an eye on spreading

Better Native Alternatives to Consider

Before planting Athel tamarisk, consider these native alternatives that can provide similar benefits without the ecological concerns:

  • Desert Willow (Chilopsis linearis): Offers similar wispy texture with beautiful orchid-like flowers
  • Fourwing Saltbush (Atriplex canescens): Excellent salt and drought tolerance
  • Jojoba (Simmondsia chinensis): Tough desert shrub with attractive form
  • Brittlebush (Encelia farinosa): Cheerful yellow flowers and silver foliage

The Bottom Line

Athel tamarisk is undeniably a survivor that can thrive where other plants fear to tread. However, its aggressive nature and non-native status make it a questionable choice for responsible gardening. If you’re drawn to its drought tolerance and airy texture, consider exploring native alternatives that can provide similar benefits while supporting local ecosystems.

Remember, gardening isn’t just about what survives – it’s about creating landscapes that work harmoniously with the natural world around us. Sometimes the toughest choice is saying no to the toughest plant!

Tamarix aphylla is also known as...

Often we refer to plants by their common names. When shopping for plants the scientific name is the best way to positively identify the plant species you desire. But some plants have more than one name! While it doesn't happen often, nurseries might display one name while you're searching for another. Tamarix aphylla is also known as:

Tamarix articulata | USDA symbol: TAAR3

Why do some plants have more than one name? Over time plant species may be renamed for a few reasons:

  1. Botanists in different regions named the same plant without knowing it had already been classified.
  2. A species was reclassified after scientific advances in, for example, DNA analysis.
  3. Slight variations within a species are sometimes mistakenly identified as entirely new species.

Wetland Status

The rule of seasoned gardeners and landscapers is to choose the "right plant for the right place" — matching plants to their ideal growing conditions, so they'll thrive with less care and fewer inputs. But the simplicity of this catchphrase conceals how tricky plant selection can be if you don't have the right information. While tags on nursery plants list watering requirements, there's more to the story.

Knowing a plant's wetland status can simplify the process by revealing the interaction between plants, water, and soil. You might be surprised to learn that popular landscape plants are wetland species! And what may be a wetland plant in one area, in another it might thrive in drier conditions. The table below gives insight into the preferred growing conditions of this plant throughout its geographical distribution.
