Hi Alex Achillea is a perennial. I'd get your Buddleia into the ground if it were mine.

I agree on both issues

I've just planted two Buddleia Jazz....one in the ground and one in a pot. Should I give the potted one some protection then, folks...it's only a baby!

I agree as well Alex, mine are all in pots and I have never lost one, even in that last hard winter. You have soil to plant in your Buddleia will be better off and should thrive.
Lovely colour on that Achillea.

Thanks for the advice, it was much appreciated.

The Buddleia is in a pot,a s I have no space in the ground for it, and the best place for it to get Sun is round the front of the block which is concrete.

So, Izzy and I would like to be assured that ours will eb fine lefty outside in pots in the winter without having to fuss over them. Is this correct?

Ok..Alex & Izzy in both your cases I would protect with bubble wrap. My plants are quite well established and get protection of sorts from all the other pots and plants next to them. Also Alex I stand my pots on bark chippings over the winter, concrete can be very cold on the roots.

O.K. Thanks. I take it just general use bubble wrap from Ryman's stationery shop would do, and I can use bark chippings from the back in a pot stand to keep the pot off the concrete.

Would a fleece jacket be needed for harsh weather?

These are very tough plants Alex.

There was a new member that joined just a few days ago who specialised in Buddleia. I can't find them at the mo.

Although achilleas are perennials, they dislike too much wet in the winter so make sure the soil they are planted n is well drained. Also make sure they aren't sitting under wet leaves that have come off trees

Thanks.

Thank you from me too...I'd moved them all under the protection of trees....but there will literally be thousands dropping now, Andrew! Looks like I'll be moving them again tomorrow.LOL.

I definitely wear a fleece when I do the gardening in this weather, LOL.

I only have a B&Q garden centre near me and yes, they do thin fleeces on rolls, but there does not appear to be any bubble wrap. I have looked all over on various occasions. It looks like stationery bubble wrap is the only alternative.

Plus, I think someone was not very happy that I lanted one, as the ot out the front was on its side, and a huge heavy pot doesn't just "blow over."
