Found on the side of my house where the garden is unused. I know previous owners had bamboo in their garden, though I’m not sure if they had planted any. I stumbled upon these guys, and was in wonder by their purple leaves…though I don’t know if bamboo sprouts quite like that. It’s coming up in a bunch of weeds, so maybe this is a weed I’ve never seen? Both pictures are individual bunches; just two groups altogether, around 4 feet apart.

    Rule out bamboo. Leaves not correct for bamboo. Have forgotten much of what I worked with in landscape industry so cannot id plant yet. Still looking. Anybody have any other guesses? Stem looks fleshy.

    Not bamboo…
    Japanese Japanese knotweed (Polygonum cuspidatum)
    You’re going to want to start digging those out… they are bad news.

    You can eat those, too. Might be a good way to control them? They might also be an attractant for Japanese Beetles. “Japanese beetles, caterpillars and “rust” fungi . . . control the weed in its native habitat.”

    It looks very much like a peony sprouting for spring. They rise up in a shade of rusty-purple only to have their leaves unfurl to a lovely green. If this is indeed what it is, look forward to a treat of beautiful blossoms!
