I made an impulsive purchase of a whisteria about a month ago.  The flowers were coming in to bloom and looks really lovely.  I’ve repotted it and now the flowers are dying off.  Will the plant flower again this year, or is that it for the season?  

I’ve always wanted a whisteria, but now I’m worried that it won’t survive up here in Scotland.  Does any have any advice or success stories about whisteria in Scotland?

Kind regards,

    What's the temp?

    Afaik, Wisteria blooms only once. Kinda didn't pay much attention because where I lived wisteria was considered sort of invasive weed.

    The temperature here is about 18 - 20c in summer, but not every day.  Winter it can get to -10c, but not for a very long time.  It’s normally 2c to -5c over the winter.

    I’ve heard it can be invasive.  Maybe I’ll leave it in the pot.

    Huh, the temp is a tad higher than ideal. Not sure if it will survive. Give it shade.

    Rootbound potted wisterias do well, so no problems. Don't give it much water during flowering season, helps it to flower. It sounds harsh but flowering is the plants' way to trying to pass on its genes. They think the process is necessary when they think they are dying and break into blooms.

    Wisteria is not only invasisve, but toxic to pets and sometimes to humans.

    I had,wisteria in my last garden in Belgium with a temperature range of -20C and sometimes worse in winter and then 38C possible in summer heatwaves.   My wisteria sometimes flowered twice in a good summer.

    In this new garden I have inherited two mature wisterias which produce a healthy second flush in summer, probably enjoying the heat which is steadier and usually not humid.   Pruning is key to good flower production. 

    Wisteria is not invasive except in the sense that when happy it can grow very long stems.  There's one up the road form us that has escaped from its arch at the entrance to the garden and sent a stem about 30 or 40 metres along the hedge.   Looks fab.  I keep the trunks of ours bare and rub or cut off any shoots that form up it as I am now planting shade lovers in the bed below.  I also trim off any long stem heading in the wrong direction up top.  Don't want it creeping under gutters and roofs.
