Is my astilbe spreading?

4 years ago

I planted a baby Younique Salmon Astilbe 2 months ago, it was just a twig looking thing. It’s my first time with astilbe. It gets direct western sunlight for at least 8hrs and is in compost/leaf mulch-amended clay. I didn’t expect it to do much as I have seldom watered it, no fertilizer. I wasn’t planning on keeping it there because I thought it was too much sun. There is another YS astilbe from the same supplier 3 ft away in shade that has barely even grown and these things aren’t surrounding it. Are these just weeds growing around that coincidentally look like my astilbe or is this plant spreading already? If so, can I dig the little clumps up and plant them in other beds?

Hard to see but I have never seen astilbe spread like that. It says online that astilbe form a compact mound which is what mine do.

Nothing visible is Astilbe.

What you have there appears to be an aggressive spreading weed rather than an astilbe. :(

Definitely not Astilbe. Compare with Rorippa sp.:

is her original plant even an astilbe??

did you plant flower and drop seed.. if not.. then its not spreading underground in 2 months.. nothing grows that fast .. especially since you didnt pamper it ...

and many of those things dont have leaves that are close to A at all.. you need to look a bit closer ....

Wow. You all are totally right and I am so bummed. I looked at that link, then downloaded a plant identification app…. And yes. It is a weed :( I found my dead astilbe. Thanks everyone! God knows how long I would have let these grow proudly. My husband thinks this is hilarious 🫠

The dead stem doesn’t look like Astilbe either.
