I found this tiny 'fragment' of VLM on my beach, looking like it had been freshly washed up. I slowly pulled it out, to reveal an established plant, well rooted!
It's amazing how tall these plants can grow. I placed this dried piece next to my rake for comparison. It begins at the acorn cap in the bottom of the pic, all the way up to the plastic attachment of the rake. They can create an impenetrable jungle in deeper water.
When they're all dried out, they remind me of shed snakeskins!
This plant is tenacious, resilient, super-adaptive and versatile, with some good-looking parts too. Kudos, variable milfoil, you are a very successful plant - ... but just look - this is the floating mass of sheared off plants we retrieved in the small area of our beach after a weekend of boating! It's about 90% milfoil.
