    If you fail to plant at the correct time, could you prevent the perennial from flowering on time?

    Hi there, the flowering time of mature pot-grown plants should not be affected. Plants will need a bit of extra care e.g. if you plant in the summer, it’s important to keep an eye on the watering but new plants do require some extra attention in the first year anyway. Hope that helps!
