New clematis when to plant out

I have just bought a young clematis plant Hagley Hybrid in a pot. It has about 12 inches of new growth. Looking ahead at the weather forecast would it be best to leave it in its pot either in a sheltered place or in cold greenhouse rather than plant out?

    I'd plant it now. Group 3 Clems are pretty tough.

    For me it rather depends on how big it is ... I often find it best to grow clematis on in a pot for a year before planting out.

    Yes, plant it. It would need to be several degrees below to cause any significant damage. 
    Besides, you'd want to prune it a bit anyway so nature would be doing it for you!

    Could we see a photo of your clematis please @Grajean … then we can give firmer advice. 😊

    The weather isn't a problem for  Group 3s, as they're very tough in that sense, the size of the plant, and your climate and conditions are the factors.
    Many plants sold, especially in supermarkets etc, are very young -little more than last year's cuttings,  and benefit from being grown on for a while to ensure they're strong enough to withstand slugs and other problems. A plant with a good root system will do better.  :)

    No need for them to be indoors though @pandakoalagirl49lS9c8QR_ Outside in a sheltered spot is all they need, if you've bought them from an outlet where they've been kept inside long term.  :)

    It also rather depends on whether it's come from a cosy greenhouse or polytunnel or has been hardened off.   Personally, I like to grow them on in pots for their first year so I can nurture them and let them develop a strong root system before I plant them out.

    I would keep it in a sheltered spot and feed and water it then, the minute I see a root at the bottom, pot it on in to a deeper pot with good JI3 type compost.  Keep an eye on it and plant it out next autumn or spring.

    I was stupidly assuming 12" growth on a gc sized plant, not a £2 supermarket special! If it's the latter then I'd be a lot more careful with it - I've got clematis I bought from Morrisons in 2019 still in pots!

    It's why several of us have suggested caution, and a photo @mikeymustard ;)
    I've had some from Morrisons in the past too- good healthy plants, but they were all grown on for a good while, until the planting areas were prepped [nothing here at the time] and then they were nice and sturdy, and well developed, and ready to go.

    Thanks everyone for your comments. I have decided to pot it on and keep in sheltered place until cold spell over. Sorry no photo.
