Here at Kelways, we offer an extensive selection of perennials all year round, not simply when the plants are "doing their thing". This means that you can take advantage of the opportunity to plant some of them out-of-season in the autumn and early spring, when they will root quickly and give you stunning displays the following season, so whilst they may not look "the bee's knees" immediately if you are ordering outside of the normal flowering time, you can be assured of an amazing result.
Please note that depending on the season, some perennials may be cut-back in their dormancy period as well as when the plant is simply too tall for us to be able to safely pack it. This in no way will detract from it's performance in the garden.
