Timber Posts with rope swags

Am looking for some advice.  Having 3 Timber posts with rope swags to grow roses and hang feeders.  Bit worried that if I use pressure treated normal posts will they rot much quicker than green oak. Due to their light colour I was going to stain them.  Ive read on the net that that PT posts are not good for a wildlife garden and could be toxic for the birds.  I need 9 250cm posts.  Was originally going for green oak but my landscaper has suggested normal PT posts to save me money.  Also worried that PT posts will not last as long as green oak.  Any advice would be appreciated.

    I'm not sure why anyone would say pressure treated posts are bad for wildlife. Very odd. They may not be as long lived as the oak, but if they're put in properly, they'll last for years and years. I've never used anything else.

    My pergola is made of pressure treated wood.
    I built it about 25 years ago and there's no rotting yet of anything and it's hosts all sorts of wildlife amongst the roses that grow over it.

    Many years ago I visited Hyde Hall and the rose garden there also had posts and rope swags for the climbers and ramblers - looked great.
    Go for it

    If there is a PVC fencing company near you (I have one) they must have timber looking plastic posts to use as uprights?  I was lucky earlier this year to find my yard had some end of stock ones in a corner that he let me have for €5 each per 8ft length.  They'll never rot.
