there is a very active perennial forum..

where are you.. big city name.. is you plant cold affected?? .. id like to confirm the ID .... your picture is out of focus.. so its hard to tell ... straight down pix are usually wonky for us...

i might let it grow this year.. and divide it next year ... give the root mass an extra season to mature.. before you cut it into pieces ...

regardless ...if you want to 'divide' your plant.. dig it up.. divide it.. and replant it ...

i find it hard to understand.. that you dont want a larger plant.. but rather.. a single plant.. as most of us would want bigger.. that said.. its your plant. in your yard.. so do whatever makes you happy ..

Swamp milkweed is a natural clump former. Generally, multiple stems originate from the fat, fleshy root (not a rhizome) and they are considered a single plant. You can divide it if you like but they are not long lived in the garden and rarely last more than 3-5 seasons.

I’m in Dayton, OH ZONE 6.

To ken_adrian I don’t have much space. just room for 3 or 4 plants. I think I’ll just wait and see how it looks when it’s all up. thx.
