The plants have grown from seeds "contaminating" some multipurpose
compost I
bought and I'm curious to know what they are.
I posted a link for these three as seedlings a few weeks ago.
They have grown a lot since then - any ideas anyone?
The stalks are quite fleshy and not woody so I don't think they are tree
seedlings.
Suggestions?

Hemp Agrimony


I think you may be right - Hemp Agrimony (eupatorium cannabinum). I've just
Googled for images and while mine aren't in flower yet the foliage looks
right. Google says it is a wildflower attractive to butterflies and can even
be bought from a number of plant nurseries, which would perhaps imply it
isn't a pernicious weed?

Anyone know if it invasive? Presumably it has a habit of seeding itself
everywhere - which I how I got it "free" in my multi-purpose compost.

It looks like the plants are for keeping rather than composting, so the
question now is whether to set them out in a flower border or give them a
little border to themselves.

Anyone growing this?

David.


There's a clump 3 or 4 miles down the canal. As British wild flowers go
it's one of the bulkier ones. Stace says that it grows to 1.5m, and I
observe it to form considerable clumps - I guess that is spreads by
rhizomes. (Not as bad as the 20 yard clump of goldenrod that's colonised
one roadside verge.)
