Cottonwood bottoms along the Upper Missouri are Montana’s classic yellow-morel highway in May and June, with wild mint and milkweed joining the riparian pantry later in summer.
Map pins mark public-land access hubs—not secret patches. Walk in with restraint, know look-alikes, and forage with restraint.
The Yellow Morel

The yellow morel is the first great prize of the foraging year. It emerges in the warming days of May and June, primarily in the rich, loamy soils of river bottoms. Look for them beneath the towering eastern cottonwoods along the Missouri, the Yellowstone, and the Clark Fork rivers. The old local wisdom suggests waiting until the lilac leaves have unfurled to the size of a rabbit's ear. The yellow morel has a honeycomb cap that is attached continuously to the stem, a critical detail that distinguishes it from toxic lookalikes.
Harvest Window: May through June. Habitat: Riparian zones, cottonwood bottoms, and old apple orchards. Access Rules: Abundant on BLM lands along the Missouri River and in National Forest riparian zones. Limit of five gallons per day for personal use on USFS land. State parks and National Parks are strictly off limits.
Cottonwood

The towering cottonwoods that line Montana's rivers offer a powerful medicinal resin. In the late winter and early spring, before the leaves emerge, the leaf buds swell with a sticky, highly aromatic resin known as the Balm of Gilead. This resin is powerfully antimicrobial and anti-inflammatory. It is traditionally infused into oil to create a healing salve for cuts, burns, and sore muscles.
Harvest Window: February through April, while buds are tightly closed and sticky. Habitat: Riparian zones and river bottoms statewide. Access Rules: Abundant on BLM and National Forest lands. Harvest buds selectively, or better yet, gather them from branches that have been freshly downed by winter windstorms.
Stinging Nettle

Despite its formidable defense mechanism, the stinging nettle is one of the most nutrient-dense greens available in the wild. It thrives in moist, disturbed soils, often growing in dense patches along riverbanks and old homesteads. You must wear heavy gloves to harvest the tender top leaves and shoots in the spring. Cooking or drying the leaves completely neutralizes the formic acid that causes the sting, leaving a dark green vegetable that tastes like a richer, earthier spinach.
Harvest Window: May through June, before the plant flowers. Habitat: Moist, rich soils, riparian areas, and disturbed ground statewide. Access Rules: Widely available on public lands. Allowed for personal use.
Wild Onions and Chives

Several species of wild alliums grow across Montana, from the nodding onion (Allium cernuum) on dry, south-facing slopes to wild chives (Allium schoenoprasum) along wet riverbanks. The entire plant is edible and carries a sharp, pungent flavor. The crucial identification rule for any wild allium is the smell. If it looks like an onion but does not smell unmistakably like an onion or garlic, do not eat it. It could be the deadly death camas in its pre-flowering stage.
Harvest Window: Spring through mid-summer. Habitat: Varies by species; dry slopes to wet meadows. Access Rules: Allowed on BLM and National Forest lands. Harvest selectively, taking only a few plants from any given cluster.
The Medicinal Plants
The Broadleaf Cattail

The cattail is the supermarket of the marsh. Almost every part of the plant is edible at some point in its life cycle. In May and June, the tender inner cores of the young shoots can be pulled and eaten like asparagus. In July, the male flower spikes can be shaken into a bag to collect the bright yellow pollen, which is rich in protein and can be mixed into flour for baking. In the late summer and fall, the starchy rhizomes can be dug from the mud and processed into a heavy flour.
Harvest Window: Shoots in May/June; pollen in July; roots in late summer/fall. Habitat: Marshes, pond edges, and slow-moving water statewide. Access Rules: Abundant on BLM and National Forest wetlands. Ensure the water source is clean, as cattails act as biofilters and absorb heavy metals and agricultural runoff.
Look-alike warnings
Never eat a wild plant or mushroom unless you are certain of the identification. Death camas mimics edible camas before flowering; false morels can resemble true morels; death-cap buttons can look like young puffballs; water hemlock and poison hemlock kill. When in doubt, leave it.

- Nearest town: Fort Benton
- Focus: Mushrooms
- Access: BLM personal use is generally allowed within local harvest limits. Private ranch frontage is extensive—respect fences. National Wildlife Refuges along the river usually prohibit foraging.
- Legal reminder: National Parks and Montana State Parks prohibit foraging. Tribal lands require permission. USFS personal use is often capped at five gallons per day—confirm with the local ranger district.
- Safety: Carry bear spray in berry and burn country. This guide is informational, not a substitute for field guides or local expertise.
