Thickspike Wheatgrass: A Hardy Native Grass for Tough Garden Spots

If you’re looking for a no-fuss native grass that can handle whatever Mother Nature throws at it, let me introduce you to thickspike wheatgrass (Elymus lanceolatus). This perennial bunch grass might not have the flashiest name in the plant kingdom, but what it lacks in marketing appeal, it more than makes up for in reliability and toughness.

What Makes Thickspike Wheatgrass Special?

Thickspike wheatgrass is a true North American native, naturally occurring across an impressive range from Alaska down through Canada and into the lower 48 states. You’ll find this adaptable grass growing wild in places like Alberta, British Columbia, Montana, Colorado, and many other western and northern regions. It’s the kind of plant that says I belong here – because it literally does!

This perennial grass forms attractive clumps with blue-green foliage that adds a lovely textural element to any landscape. The distinctive seed heads that give it the thickspike part of its name appear in summer, creating visual interest and providing food for wildlife.

Why Gardeners Love (and Should Love) This Grass

Here’s where thickspike wheatgrass really shines – it’s practically bulletproof once established. This hardy native thrives in USDA zones 3-8, making it suitable for a wide range of climates. Whether you’re dealing with scorching summers or frigid winters, this grass has likely seen worse in its natural habitat.

The real magic happens when you consider its water needs – or rather, lack thereof. Thickspike wheatgrass is exceptionally drought-tolerant, making it perfect for:

  • Xeriscaping and water-wise gardens
  • Slopes and erosion-prone areas
  • Prairie restoration projects
  • Low-maintenance naturalized areas
  • Those challenging spots where other plants give up

Growing Conditions and Care

The beauty of thickspike wheatgrass lies in its adaptability. This grass prefers full sun but can tolerate some shade, and it’s not particularly picky about soil type. Whether you have clay, sand, or something in between, this grass will likely make do.

Regarding moisture, the wetland status varies by region. In places like Alaska and the Arid West, it’s classified as Obligate Upland, meaning it almost never occurs in wetlands. However, in regions like the Great Plains and Midwest, it’s considered Facultative Upland, meaning it usually prefers non-wetland conditions but can tolerate some moisture.

Planting and Establishment Tips

Getting thickspike wheatgrass established is refreshingly straightforward:

  • Plant in spring or fall when temperatures are moderate
  • Ensure good soil contact when seeding
  • Water regularly during the establishment period (first growing season)
  • Once established, reduce watering significantly – this grass prefers to tough it out
  • Minimal fertilization needed; too much can actually make it less hardy

Wildlife and Ecological Benefits

While thickspike wheatgrass may not be a pollinator magnet (it’s wind-pollinated, after all), it provides valuable habitat and food for various wildlife species. Birds appreciate the seeds, and the grass structure offers nesting sites and cover for small animals. As a native species, it supports the local ecosystem in ways that non-native alternatives simply can’t match.

Is Thickspike Wheatgrass Right for Your Garden?

This grass is perfect if you want a low-maintenance, drought-tolerant native that can handle challenging conditions. It’s ideal for naturalized areas, prairie gardens, and anywhere you need reliable ground cover that won’t demand constant attention.

However, if you’re looking for a showstopper with flashy flowers or dramatic seasonal color changes, you might want to pair it with more ornamental natives. Think of thickspike wheatgrass as the dependable friend in your garden – not necessarily the life of the party, but always there when you need it.

For gardeners committed to supporting native ecosystems while creating beautiful, sustainable landscapes, thickspike wheatgrass deserves serious consideration. It’s proof that sometimes the best plants are the ones that simply do their job well, year after year, without any drama or fuss.

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 work and fewer inputs. But the simplicity of this catchphrase conceals how tricky plant selection is. While tags 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. Surprisingly, many popular landscape plants are wetland species! And what may be a wetland plant in one area, in another it might thrive in drier conditions. Also, it helps you make smarter gardening choices and grow healthy plants with less care and feeding, saving you time, frustration, and money while producing an attractive garden with greater ecological benefits.
