Behavior

Crested Wheatgrass is a hardy, cool-season perennial grass that is among the first to "green up" when the snow melts in early spring. It grows in dense clumps or bunches, spreading primarily through seeds rather than underground runners. While it doesn't move like an animal, it exhibits a fascinating seasonal rhythm of rapid spring growth followed by a mid-summer dormancy period to survive heat and drought.

In the backyard ecosystem, this grass serves as a reliable anchor. It provides critical early-season grazing for local wildlife like deer and rabbits, and its dense structure creates a sturdy micro-habitat for ground-nesting insects and small mammals. Because it is highly competitive and drought-tolerant, it often dominates the landscape where it is planted, providing a consistent visual backdrop throughout the year.

Camera Tips

Because Crested Wheatgrass is stationary, your goal is to capture its structural beauty and the wildlife it attracts. Use a camera with a macro or close-up focus setting to document the intricate 'comb-like' structure of the seed heads. Positioning your camera at a low angle, roughly 6 to 12 inches off the ground, will give the grass a majestic, forest-like appearance and make it much easier to catch small visitors like grasshoppers, ladybugs, or ground squirrels that frequent the stalks.

Time-lapse mode is particularly effective for this species. Set your camera to take a photo every few hours during the spring to watch the dramatic 'green-up' or the unfurling of the seed heads. For the best lighting, side-lighting during the early morning or late afternoon (the golden hour) is essential; it highlights the fine textures and tiny 'hairs' on the wheatgrass, making the golden stalks glow against a darker background. Avoid midday sun, which can make the grass look washed out and flat.

To capture animal interactions, place your camera near a dense patch of the grass where you see signs of foraging. Many birds, like Sparrows and Finches, love to land on the sturdy stalks to eat the seeds in late summer. If you are using a motion-activated camera, ensure the sensitivity is adjusted or use 'zone masking' so that the wind blowing the grass doesn't trigger hundreds of empty videos. Aim for a sheltered spot or a thicker clump that moves less in the breeze to minimize false triggers while still catching the heat signature of a passing bird or rabbit.

Similar Species

Species that look similar or are commonly confused with Crested Wheatgrass.

Bluebunch Wheatgrass

Bluebunch has a much slimmer, more upright seed head compared to the wide, comb-like 'crest' of the Crested Wheatgrass.

Intermediate Wheatgrass

This species grows taller and has longer, more widely spaced seed heads without the distinctive 'comb' appearance.

Frequently Asked Questions

As a plant, Crested Wheatgrass is 'active' during daylight hours when it performs photosynthesis. However, for the best visual display on your camera, the 'golden hours' of sunrise and sunset highlight the texture of its seed heads beautifully.

Crested Wheatgrass is very easy to grow from seed in well-drained soil and full sun. It is often sold in 'reclamation' or 'dryland' seed mixes. Once established, it requires very little water and no fertilizer, making it a great low-maintenance option for natural areas.

Crested Wheatgrass doesn't 'eat' in the traditional sense; it is a primary producer that creates its own food from sunlight, carbon dioxide, and water. It draws essential minerals and nitrogen from the soil through its deep, aggressive root system.

Yes, they are very common in suburban areas throughout the Western US and Canada. They are frequently used for erosion control on hillsides, along roadsides, and in low-maintenance 'natural' landscaping projects.

The easiest way is to look at the seed head. Crested Wheatgrass has a flattened, 'crested' spike where the seeds are crowded and spread outward like a comb. Bluebunch Wheatgrass has a much narrower, more elongated spike with seeds that stay close to the stem.
