I had one like this - Sedum Autumn Joy. I moved mine alright, right out to the trash collection bin. I loathed how they fall apart after blooming like this. It's not your fault. Nothing you can do to fix this. It's just what they do after going to seed. I replaced mine with hydrangea which stays upright. If you wish, however, you may move it now. These plants are tough, but this is the time to move them if you wish. They do OK in shade as well. You can also divide the crown for multiple plants.

Thanks Bathgate I honestly feel like you did as they won't stand up and I thought it was my fault for placing it in the wrong place, I may well dump it and now I won't feel so guilty 😲

LOL I have no regrets. I do enjoy the hydrangea though. The flowers last a long time and the leaves have wonderful fall color.

Its surely just dying down for the winter, when it more or less disappears altogether. In my garden they don't fall down until they have finished flowering, when you can cut off the flowered stems without any problem. I did this about two weks ago.If you want to move it into a sunny spot cut the dead stems off and go for it. Isn't it worth keeping just for the butterflies? You can stick a few spring flowering bulbs close to the roots to fill in the gap until the new leaves start to grow next year.

Mine have new buds at the very bottom, I keep the stems on to protect those but you should be able to trim those and they'll come again. I have mine in pots so you could dig them out and pot them? I'm with Steragram, they're for the butterflies and bees, and do last very well into the winter.

If it won't stand up during the growing season, then it needs a sunnier place, they do best with as much sun as possible. Flopping over as it has during autumn usually only happens when its been hit by frost.. I'm not too keen on these either, but I try to fit one in somewhere purely for the insect population. Especially Red Admiral butterflies, who seem to love it when its planted in sun.

No they don't. That's why I dug it up and trashed it. They flop over and look just awful just like this one. This one obviously had enough sun. Look at it. Not something i want in front of the house. I have lots of other plants for the butterflies. They don't all have to flop.

If you do the Chelsea chop (cut it right down when it is the Chelsea show) then the new growth flowers a little later, but on shorter stems so they do not fall over. OR, as I do you could put in twigs round the base of the plant which the stems then lean on and hide as they flower.

What it comes down to basically is do you like the flowers or not? For me they are attractive all year until the flowers die and the I simply cut them off. End of problem. If you like them most of the year then moving to a sunnier place would help.If you don't like them then give the plant to somebody else???

Transplating will not solve the problem. Once they produce seeds, they begin to collapse. I just got tired of looking at this every year and felt it was time for a change. Sometimes you just want to change things up. That's your decision.

Agree with those who advocate keeping one of these for late butterflies. Mine are covered in bees and butterflies when many other flowers are going over and I wouldn't be without them for that reason. Sometimes I cut the stems off and sometimes I leave them until spring. It just depends on how far I get with the garden before it gets too cold and wet. I'm intrigued by the idea of the Chelsea chop for these plants. Might try that with one of them next year.

LOL It's not your garden. Let him do his own garden and you do you. He's clearly not an idiot and knows full well what this plant is all about.

I've heard of the Chelsea chop with these plants also, keeps the stems shorter & more but smaller flowers. Mine seems to stand up ok all summer & only falls after a hard frost when it can be tidied up.

Yes you can move it now, in a full sun situation they stand sturdy and errect, yours look very leggy and do look like they have grown for the light, this will make them flop as will the clump being too large, I always divide mine in the allotment garden every few years, but like as mentioned already, they look great in a large container and look good with some ophiophogum planted round the base.
