Successional means you can have the feel of a flower bed, filled with varieties of beautiful plants that showcase their best in flower, colour or scent all through the season, which is particularly vital if you have a small space, so you are not left looking out onto a barren space over winter. 

Ecological means I will choose the right plants for the right place.  Matching suitable plants to the growing conditions of your space not only makes it easier for you to maintain, but also ensures they perform for you because they are happy in their home.  This is particularly important on balconies which may be sun-scorched, or shaded from sun and rain on lower floors, whilst roof terraces are often very exposed to the elements.

Sustainable choices are made as much as possible, from buying local, to use of recycled materials and manufacturing methods in planters and troughs, peat-free compost and drought-tolerant perennial plants that come back year after year.
