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.

List
Acanthus sennii
A spectacular and unusual plant, originating from the highlands of Ethiopia, Acanthus sennii has incredibly spiky, holly-like leaves with prominent white veining and produces a central spike of bright orange-red flowers from late summer into autumn. Surprisingly hardy, it will die back in autumn and re-emerge in spring, but can also be grown in a large pot in a conservatory where it may produce an evergreen display. Shelter from strong winds and cane the stems to offer extra support. Keep dry in winter to prevent root rot.

Alchemilla mollis
A beautiful perennial which is a must for every garden. It has wonderfully scalloped leaves which catch water droplets and produces a frothy covering of small yellow flowers throughout spring and summer. It can have a habit of self-seeding quite freely, so cut off the seed heads carefully after flowering to minimise any unwanted spreading.
