Well, you don't have much to lose at this point. I would stick them in a well-drained mix, use rooting hormone, keep a clear tent on the top to hold in humidity (but vent enough that the don't rot), and provide bottom heat. See what happens, it might work.

Thanks for encoragment and tips. I have never tried heat. christmas cati , jade and viollets just jump up and grow.hard woods I haven't tried yet.

Not really off topic if you consider you can make jelly from rowan berries. I think that counts as 'fruit'.

If you have enough cuttings I'd also try a few outdoors without the heat and plastic bag. Just ensure they don't dry out and leave them alone until next year. Rowan is a totally hardy tree so it might work. What made the parks people kill it???

Just a thought - any chance there are a few stray berries still around on the ground where it was growing? They would be worth a try. You might even find a seedling or two.
