Phragmites (European Common Reed)
Phragmites australis subsp. australis
A very tall invasive reed that forms dense stands in wet areas and ditches. It has feathery seed plumes and blue-green leaves, and can grow taller than a person, crowding out wetland plants.
Invasive phragmites — a very tall, dense stand of beige reeds.

At a glance
- Key clue
- Very tall reed with feathery plumes in dense stands
- Best months
- August to October, when the feathery plumes are full and the stands are tallest
- Often found
- Wetland / pond edge, Ravine edge, Vacant lot
- Easiest to remove
- Summer, small dry-ground patches
Why it's prohibited
Invasive phragmites forms thick, tall stands — a monoculture that crowds out native wetland plants and offers little habitat value for birds, fish, and other wildlife. It spreads by seeds and creeping roots, and can clog ditches and shorelines.
Main identification features
- Very tall reed, often 2–5 m, growing in dense stands
- Feathery, fluffy seed plumes (tan to purplish) at the top in late summer
- Blue-green leaves during the growing season; tan, rigid stems
- Dense, monoculture stands in ditches, wet ground, and shorelines
- Stems stay standing through winter as a beige thicket
Similar plants & look-alikes
- Native phragmites — The native reed grows in sparser stands, is shorter, with reddish stems and a less dense plume; the invasive type forms tall, dense, tan-stemmed thickets.
- Cattails — Cattails have the familiar brown 'hot dog' seed head and flat strap leaves, not a feathery plume.
Month-by-month identification timeline
August to October, when the feathery plumes are full and the stands are tallest.
April–May (Early spring)
· 0.3–1 mNew green shoots emerge from last year's roots among the standing dead stems.
Green shoots rising among old beige canes.
June–July (Summer)
· 1.5–3 mStems shoot up quickly with blue-green leaves, thickening the stand.
Fast, tall growth; blue-green leaves.
August–September (Late summer)
· 2–5 mTall stems are topped with large feathery plumes.
Feathery tan-to-purple plumes — easiest ID.
September–October (Fall)
Plumes turn fluffy and pale as seeds mature and catch the wind.
Fluffy pale seed plumes.
Winter (Dormant)
Leaves drop; rigid beige stems and faded plumes stand through winter.
Dense standing beige thicket.

How to remove it safely
Safest resident-friendly approach
For small patches on dry ground, cut the stems low and dig out the roots, repeating through the season to weaken the stand. Because phragmites usually grows in wet areas, removal there can be difficult and may require special care or permits — check before working near water.
Tools & protection
- Gloves
- Loppers or a sturdy cutting tool
- Spade for roots (small/dry patches)
Best time of year
Cut in mid-to-late summer and repeat; remove before plumes release seed.
Monitoring
Re-check the stand each year; phragmites resprouts vigorously from roots.
Prevent regrowth
Keep cutting regrowth to drain the roots' energy; monitor and re-treat for several years.
What not to do
- Don't work in or near water without checking permit and protection rules first
- Don't let cut plumes spread seeds; bag them
Disposal
Bag plumes and seed heads for the garbage. Let cut stems dry out away from water; follow City rules for the rest of the material.
Safety cautions
- Wear gloves and long sleeves; cut stems and leaf edges can be sharp
- Take care working near water or soft, wet ground
When to get professional help
Recommended for large stands or any phragmites growing in or near wetlands, ponds, or shorelines, where permits and special methods may apply.
Bag seed plumes for the garbage; dry out cut stems away from water. Avoid spreading seeds or root fragments.
